1.0 Executive Summary 1.1 The assessment has considered the effects of the Plaistow Hub development at London

Road and Valetta Grove on the levels of daylight and sunlight received by nearby residential properties. The analysis also considers the levels of natural light within the proposed units and the effects of the development in terms of overshadowing. The effects of the two component developments have been considered together.

1.2 Overall, the assessment has considered the effects of the development on daylight levels experienced by 191 windows serving neighbouring properties. Of these windows 105 have been assessed in terms of sunlight availability. Within the development, the assessment has considered the daylight levels that will be experienced by 323 windows and 171 main rooms and bedrooms, and the sunlight levels that will be received by 196 south facing windows. Proposed areas of open space within the development and the Valetta Grove Open Space have been assessed in terms of the BRE two-hour sunlight contour analysis (overshadowing assessment).

1.3 The daylight assessment demonstrates that the development will not cause unacceptable effects in terms of neighbouring properties’ daylight conditions. The majority of the neighbouring windows assessed will either comply with the BRE guide levels for ambient daylight (VSC) or will experience only marginal effects as a result of the development.

1.4 The results of the daylight analysis for the proposed residential units within the development show that c. 76% and 96.5% of the proposed habitable rooms assessed will comply with the BRE guide levels for ADF and DD respectively. Good levels of interior daylight are experienced within each of the component developments.

1.5 The sunlight analysis demonstrates that all but five of the windows serving neighbouring properties that require assessment will comply with the BRE guide levels for annual and winter sunlight availability. These are isolated and marginal effects and relate to bedrooms or rooms with other windows. The of neighbouring properties will retain good levels of sunlight with the scheme in place. The sunlight analysis for the proposed residential units within the scheme demonstrates that c. 50% of the windows requiring assessment will achieve the BRE guide levels for annual sunlight. This is a typical level of compliance for an urban development project. Where lower levels of annual sunlight are experienced this is frequently attributable to the effects of generous balconies set above the windows and the rooms served by those windows experience good levels of interior daylight.

1.6 The overshadowing analysis demonstrates that all but one of the proposed areas of open/amenity space within the scheme will experience high levels of sunlight. The Valetta Grove Open Space will also continue to comply with the BRE guide level with the scheme in place. The development is considered acceptable in terms of overshadowing.

1.7 Overall, the results of the daylight, sunlight and shadow analyses for neighbouring properties and the proposed accommodation are good for an urban environment taking account of the flexible, suburban basis of the BRE guidance. It is, therefore, concluded that the London Road and Valetta Grove developments will not result in materially unacceptable impacts on the daylight levels of neighbouring residential properties. The Plaistow Hub proposal will not give rise to materially unacceptable daylight and sunlight effects in the context of the BRE guidelines and relevant planning policy.

2.0 Introduction 2.1 This report considers the effects of the proposed Plaistow Hub development at London

Road and Valetta Grove in Plaistow, London, E13 on the levels of daylight and sunlight received by nearby residential properties and open spaces. It also considers the levels of natural light that will be experienced within the new residential accommodation at the sites and the proposed areas of amenity space within the scheme. The assessment has been prepared on behalf of Red Door Ventures. The proposal comprises the construction of two groups of higher density mixed use buildings at the component sites accommodating a neighbourhood centre, commercial space and residential accommodation.

2.2 The daylight and sunlight assessment considers the effects of the London Road and Valetta Grove buildings on neighbouring residential properties on Upper Road, London Road Juliette Road, Plaistow Road, Valetta Grove, Greenwood Road, Beardsfield, Settle Point, Opus Studios and Willow Lodge. It also considers the levels of daylight and sunlight that will be received within the new accommodation in the lower floors of the development itself.

2.3 The quantitative assessment has been undertaken in accordance with the guidelines set out in the revised Building Research Establishment (BRE) report “Site Layout Planning for Daylight and Sunlight: A Guide to Good Practice” (October 2011). The Guide is intended to be advisory and does not contain mandatory standards. The introduction states:

“The guide is intended for building designers and their clients, consultants and planning officials. The advice given here is not an instrument of planning policy; its aim is to help rather than constrain the designer. Although it gives numerical guidelines, these should be interpreted flexibly since natural lighting is only one of many factors in site layout design. In special circumstances the developer or planning authority may wish to use different target values. For example in a historic city centre, or in an area with modern high rise buildings, a higher degree of obstruction may be unavoidable if new developments are to match the height and proportions of existing buildings.”

2.4 This assessment has been carried out using the following information:

Measured site survey drawings;

Photogrammetric survey of the site and surroundings;

The planning application drawings (December 2016);

Ordnance Survey Superplan digital mapping of the area;

Aerial photography;

A photographic survey of the site and surroundings.

2.5 The report is divided into the following subsequent sections:

Section 2.0 provides a brief description of the site and surroundings and the nature of the proposed development, highlighting features of relevance to the assessment of daylight and sunlight levels;

Section 3.0 outlines the scope of the assessment;

Section 4.0 provides an assessment of the impacts of the proposal on levels of daylight;


13600635v1 P3

Section 5.0 considers the proposal’s impacts in terms of sunlighting;

Section 6.0 considers the levels of sunlight and shadow within the proposed gardens.

Section 7.0 provides a summary of the assessment and our conclusions are drawn.

2.6 The assessment is supported by a series of reference plans and results tables at Appendices 1-6.

3.0 Site, Surroundings and the Proposal

Site and Surroundings

3.1 The Plaistow Hub development is composed of two component application sites on London Road and Valetta Grove in Plaistow.

3.2 The London Road site is bounded by Plaistow Station and the culverted London Underground lines to the north west, Plaistow High Street to the northeast, buildings fronting Upper Road to the south east and by Settle Point tower and adjacent residential blocks to the to the south west. The site is currently occupied a temporary single-storey building used by Plaistow and Upton Park Early Intervention Centre. Land on the western part of the site is occupied by a pay-and-display car park. There is also an existing set of steps which runs adjacent to Plaistow Station.

3.3 The Valetta Grove site is situated to the north west of the London Road site across the High Street/ Plaistow Road. The site fronts the northern side of Plaistow Road and is bounded to the north west by the Valetta Grove open space. The open space is surrounded by existing residential properties on Valetta Grove, Greenwood Road, Libra Road and Beardsfield,

3.4 The sites are in a mixed area. Plaistow Road forms a commercial road running east-west between the sites and forming a High Street west of Plaistow Station fronted by buildings in retail/commercial use. The remaining areas to the north, east and south of the sites are predominantly residential in use and contain a mix of terraced housing, low and medium rise post war estates and Settle Point, which forms an 18 storey system-built residential tower.

3.5 On the basis of this review, the assessment of neighbouring properties has focused on the daylight and sunlight levels experienced by Nos. 1-39, 41, and 55-59 Upper Road, Nos. 2-4 High Street, No. 24 Juliette Road, Nos. 4-10 London Road, Nos. 1-13A Greenwood Road, No. 210 Plaistow Road, No. 2 Valetta Grove, No. 31 Beardsfield, Settle Point, Opus Studios and Willow Lodge.

3.6 A complete description of the site and surroundings is provided in the submitted Design and Access Statement.

The Proposal

3.7 The proposed development comprises the redevelopment of the component sites to provide residential-led mixed use developments. The proposed buildings at the London Road site will rise to part 21 storeys and part 23 storeys. The development is composed of a three storey retail/commercial building within the eastern part of the site, a two storey café building in the centre of the site and a residential building of part 21 and part 23 storeys adjacent to Plaistow Station at the western end of the site.

3.8 To the north, the Valetta Grove site will accommodate new buildings of between six and 15 storeys providing a neighbourhood centre and residential units.

3.9 The layout and massing of the development is illustrated at Appendix 1.

4.0 Scope of Assessment 4.1 This section of the assessment provides an overview of the scope of the daylight and

sunlight assessment in terms of the neighbouring properties, proposed units and existing/proposed open spaces assessed.

4.2 The scale and layout of the development and the locations of the window reference points and habitable rooms assessed are illustrated at Appendices 1 and 2.

Neighbouring Properties Assessed

4.3 The assessment has provided an analysis of the impacts of the development on natural light levels within neighbouring residential properties.

4.4 As outlined in the preceding section, the assessment has considered the effects of the development on the closest windows serving neighbouring residential accommodation within Nos. 1-39, 41, and 55-59 Upper Road, Nos. 2-4 High Street, No. 24 Juliette Road, Nos. 4-10 London Road, Nos. 1-13A Greenwood Road, No. 210 Plaistow Road, No. 2 Valetta Grove, No. 31 Beardsfield, Settle Point, Opus Studios and Willow Lodge. This comprises the following windows:

4.5 All of these windows serving neighbouring properties have been assessed in terms of Vertical Sky Component (VSC). The south facing windows have also been assessed in terms of annual and winter sunlight availability.

Proposed Units Assessed

4.6 The assessment has considered the levels of light that will be received within all of the habitable rooms within the lower floors of the proposed development. The assessment has focused on the residential units between upper ground and fifth floor levels within the London Road buildings and between first and fifth floor levels at Valetta Grove.

4.8 The windows within the proposed units have been assessed in terms of ambient daylight (VSC) levels. The rooms they serve have been assessed in terms of internal daylighting (Average Daylight Factor; ADF and Daylight Distribution; DD). The south facing windows have been assessed in terms of annual and winter sunlight availability.

Overshadowing

4.9 The shadow analysis has considered the effects of the Valetta Grove development on the levels of sunlight and overshadowing within the Valetta Grove Open Space adjacent to the site. There are no other neighbouring open spaces in the vicinity of the site which require assessment in terms of overshadowing.

4.10 The proposed areas of public realm and amenity spaces within the developments have also been assessed in terms of sunlight and shadow. This includes the following areas:

London Road

Open space A1: southern landscaped strip

Open space A2: Station Square public space

- Open space A3: Roof level space above single storey café.

Valetta Grove

Open space A1: Northern amenity space

Open space A2: Park plaza public space

13600635v1 P7

5.0 Daylight 5.1 This section of the assessment assesses the impact of the proposed development on the

level of daylight received at the aforementioned window reference points and rooms.

Methodology

5.2 The daylight assessment is based on the analysis of Vertical Sky Component (VSC) and Average Daylight Factor (ADF). Neighbouring properties have been considered in terms of VSC as the room layouts, room types and other parameters required for interior daylight analyses are frequently unknown. The rooms assessed within the proposed development have been assessed in terms of VSC, ADF and DD.

5.3 The following sets out the methodology for calculating VSC, ADF and DD.

Vertical Sky Component

5.4 The level of ambient daylight received by a window is quantified in terms of its Vertical Sky Component (VSC), which represents the amount of vertical skylight falling on a vertical window. The daylight assessment has been based on three dimensional AutoCAD models constructed for the site and surroundings as existing and with the proposed development in place. The heights and locations of the surrounding buildings and the proposed development have been taken from measured site survey information, Ordnance Survey digital plan data, site observations, aerial photography of the site and surroundings and the application drawings.

5.5 The VSC level at each of the windows requiring assessment has been quantified using Waldram Tools daylight and sunlight software (MBS Software Ltd).

5.6 The BRE good practice guide outlines numerical guidelines that represent flexible targets for new developments in relation to the vertical sky component at nearby reference points. The document states that:

“If the vertical sky component, with the new development in place, is both less than 27% and less than 0.8 times its former value, then the loss of light is likely to be noticeable.” (our emphasis)

5.7 The guidelines therefore require that either the VSC target or the degree of change in daylighting are met (i.e. if the 27% target is adhered to, there is no requirement under the BRE guidelines for the resultant VSC level to remain at 0.8 times the former VSC level).

Average Daylight Factor

5.8 The BRE guide advises that the calculation of Average Daylight Factor (ADF) provides an alternative means of assessing the level of daylight received by the interior of the room served by a window. It is an appropriate means of assessment for proposed accommodation where the parameters required for the ADF calculations are known.

5.9 The calculation of ADF provides a more sophisticated method of calculating the daylight level experienced within a room than VSC as it takes into account the size and reflectance of room’s surfaces and the number, size and transmittance of its window(s), as well as the ambient daylight level (VSC) received at the window(s).


P8 13600635v1

5.10 The Average Daylight Factor (df) is defined as the average internal illuminance as a percentage of the unobstructed external illuminance under standard overcast conditions.

5.11 ADF can be calculated using the following formula (amended in the updated BRE guide, 2011):

df = TAW %

A(1-R2)

Where:

T is the diffuse visible transmittance of the glazing (a value of 0.65 is typical for double glazed clear glass; a value of 0.18 is used for obscured glazing);

Aw is the net glazed area of the window (m2);

is the angle of visible sky in degrees;

A is the total area of the room surfaces: ceiling, floor, walls and windows (m2);

R is the average reflectance (a value of 0.7 is applicable for new/proposed accommodation with light internal surface treatments1).

5.12 The BRE guide (2011) contains a separate procedure for floor to ceiling windows and glazed doors. It states that areas of glazing below the working plane should be treated as a separate window and an extra factor is applied to it to take account of the reduced effectiveness of low level glazing in lighting the room. The BRE states that a value equivalent to the floor reflectance can be taken for this factor. An adjustment factor of 0.3 is appropriate for medium timber floors and has been used in this case.

5.13 The approach to assessing internal daylighting using the ADF method is set out at Appendix C of the BRE guide. The BRE guide and British Standard BS8206 set the following minimum recommended ADF levels for different room types:

Kitchens: 2%;

Living rooms: 1. 5%;

Bedrooms: 1%.

Daylight Distribution

5.14 Finally, the analysis of daylight distribution considers the area of a room which can receive an unobstructed view of the sky. It is quantified at working plane height (+0.85m).

5.15 The BRE (2011) guide states:

“If, following construction of a new development, a no-sky line moves so that the area of the existing room which does not receive direct skylight is reduced to less than 0.8 times its former value, this will be noticeable to the occupants.”

1 A 0.7 reflectance value assumes white painted walls and ceiling (0.85) and a medium wooden floor (0.3).


13600635v1 P9

5.16 Again, the analysis of daylight distribution provides a more sophisticated method of assessing daylight than VSC as it takes into account the size of a room and the size and number of its windows. DD has again been utilised in the analysis of the proposed units and neighbouring buildings/developments where internal layouts are known.

Total 191 windows 119 (62.3%) 72 (37.7%) [45 marginal]

Table 4.1: Summary of VSC Results for Neighbouring Properties [*Marginal Impact: Within 20% of BRE Guide Level]

5.18 The results of the daylight analysis demonstrate that the majority of the neighbouring windows requiring assessment will achieve the BRE guide levels for VSC. Overall, 62.3% of the neighbouring windows assessed will comply with the guide levels. The majority of the remaining windows will experience only marginal effects.

5.19 The neighbouring properties at 41 Upper Road, 55-59 Upper Road, 2-4 High Street, 24 Juliette Road, 1-13A Greenwood Road, 31 Beardsfield and Opus Studios will all comply fully with the guide levels. The properties at 4-10 London Road, 2 Valetta Grove and Willow Lodge will all either comply with the guide levels or will experience only marginal departures from the guide levels with the two component developments in place. The effects on 4-10 London Road are attributable to the London Road part of the development, whereas the effects on 2 Valetta Grove and Willow Lodge are caused by the proposed Valetta Grove buildings.

5.20 A relatively small number of windows serving Settle Point, 1-39 Upper Road and 210 Plaistow Road will experience a greater reduction in ambient daylight. The effects on these properties are caused primarily by the London Road component development. These are isolated effects and the reduction in these windows daylight is exacerbated by the buildings’ own architecture and/or their windows’ existing outlook towards low rise buildings and open spaces at the site.


P10 13600635v1

5.21 Nos 1-39 Upper Road will experience a number of windows with levels of VSC below the guide levels with the London Road buildings in place. This is in part a function of the balconies/walkways which extend above the windows and create an obstruction and restrict daylight to the windows below. The amenity benefits associated with the balconies are generally considered to offset the associated reduction in natural light.

5.22 The BRE guide recognises the constraints to development imposed by balconies serving neighbouring properties and suggests in such instances that additional daylight calculations can also be carried out omitting the balconies. This approach serves to isolate the limiting influence of balconies on the levels of natural light received from the separate effects arising from the new development.

5.23 We have re-run the VSC analysis for Nos. 1-39 Upper Road on this basis as a secondary analysis. The results for this additional analysis are summarised below and are contained in full at Appendix 3.

Table 4.2: Summary of VSC Results for No. 1-39 Upper Road (omitting balconies) [*Marginal Effects: Within 20% of the guide levels]

5.24 This exercise demonstrates that the accommodation within the adjacent building will experience good levels of daylight if the constraints imposed by its own balcony design did not restrict the natural light levels received. All of the windows assessed will comply with the BRE guide levels or will experience only marginal impacts.

5.25 Internal daylight analyses have been run for the accommodation served by the windows assessed within 210 Plaistow Road and Settle Point (Appendices 5 and 6). The internal analyses show that the majority of the rooms assessed will in these respective buildings will achieve the guide levels for ADF and DD (92.3% and 87.2% compliance under both analyses for the respective buildings). This corroborates the results of the VSC analysis.

5.26 In summary, the daylight assessment demonstrates that the proposed development will not cause materially unacceptable effects in terms of neighbouring properties’ ambient daylight conditions. On this basis, and having regard to the urban character of the site and surroundings and the flexible suburban basis of the BRE guidance, the development’s effects on neighbouring properties are considered acceptable.

Daylight Results: Proposed Units

5.27 The development has been designed to ensure that daylight levels within the proposed units are maximised. The following table summarises the VSC, ADF and DD results obtained for the proposed residential accommodation within the development. The results are contained in full at Appendices 4, 6 and 8.

Table 4.3: Proposed Units – Summary of Daylight Results

5.28 The results of the daylight analyses for the proposed units show that c. 51% of the windows serving the proposed units will achieve the BRE guide levels for VSC. This is a typical level of compliance for a higher density urban development. Many of the windows with lower levels of VSC are set beneath balconies which reduce their access to daylight. The amenity benefits associated with the scheme’s generous balconies offset the associated reduction in natural light.

5.29 As discussed above, VSC merely provides a measure of the obstructions to skylight taken at the midpoint of each window. It does not take into account the size of each window aperture, the size, layout and nature of the room served by the window, or the number of windows serving a room. In contrast, the calculation of ADF and DD provide more sophisticated methods of calculating the daylight conditions experienced within a room. ADF takes into account the size and reflectance of room’s surfaces and the number, size and transmittance of its window(s), as well as the ambient daylight level (VSC) received at the window(s). DD reflects the size and layout of a rooms and the size and number of its windows. On this basis, the interior daylight analyses provide a better indication of the daylight conditions that will be experienced in the proposed units.

5.30 In this context, the ADF and DD results for the proposed accommodation demonstrate that c. 76% and 96.5% of the habitable rooms within the development will achieve the BS/BRE guide levels for their respective room types. When the component developments are considered separately, 82.3% and 90.3% of the habitable rooms assessed within London Road buildings achieve the ADF and DD guide levels. The levels of c0mpliance


P12 13600635v1

for Valetta Grove are 72.5% in terms of ADF and 100% in terms of DD. These are good levels of compliance with the guide levels for interior daylighting for an urban development project, particularly in the case of the DD results.

5.31 Overall, it is considered that the proposed residential units within the development will experience good levels of interior daylight for an urban development project in the context of the BRE guidance.


13600635v1 P13

6.0 Sunlight 6.1 This section of the report assesses the effects of the proposed development on levels of

sunlight at the window reference points. As noted at Section 3.0, only windows orientated within 90 degrees of due south require analysis in terms of sunlight availability. The methodology and results are discussed below.

Methodology

6.2 The levels of sunlight availability at the window reference points assessed have been calculated based on the three dimensional AutoCAD models of the site and surroundings with the development in place, using the Waldram Tools daylight and sunlight software. The calculations provide the percentage year round sunlight availability and the percentage of sunlight availability received during the winter months.

6.3 The BRE good practice guide states that the sunlighting experienced by a south facing window should receive more than 25% of annual probable sunlight hours and more than 5% of annual probable sunlight hours during the winter months.

Sunlight Results: Neighbouring Properties

6.4 The following table summarises the sunlight results for neighbouring properties. The results are contained in full at Appendix 3.

Table 5.1: Summary of Sunlight Results for Neighbouring Properties

6.5 The results of the sunlight analysis demonstrate that 95.2% of the windows requiring assessment will achieve the BRE guide levels for sunlight availability. All of the neighbouring windows serving Nos. 1-39, 41, and 55-59 Upper Road, Nos. 2-4 High Street, No. 24 Juliette Road, Nos. 4-10 London Road, Nos. 1-13A Greenwood Road, No. 2 Valetta Grove, No. 31 Beardsfield, Settle Point, Opus Studios and Willow Lodge will achieve the BRE guide levels for annual and winter sunlight with the development in place. None of these windows will experience a materially noticeable effect in terms of sunlight availability.


P14 13600635v1

6.6 Five isolated windows serving No. 210 Plaistow Road will experience marginal breaches of the guide levels as a result of the London Road development. These windows either serve bedrooms which are secondary rooms for the purposes of sunlight analysis or are served by other windows.

6.7 On this basis, the effects of the development on the sunlight levels experienced by neighbouring properties are acceptable in the context of the BRE guidance and relevant policy.

Sunlight Results: Proposed Units

6.8 The following table summarises the sunlight results obtained for the proposed residential accommodation within the development. The results are again contained in full at Appendix 4.

No. windows assessed



London Road 64 windows 32 (50%) 32 (50%)

Total 196 windows 111 (56.6%) 85 (43.4%)

Table 5.2: Proposed Units – Summary of Sunlight Results

6.9 The results of the sunlight analyses for the proposed units show that half of the windows assessed will achieve the BRE guide levels for annual sunlight and 57% will comply in terms of winter sunlight. These are typical levels of compliance for the lower floors of a higher density development in Inner London.

6.10 In most cases, the windows experiencing lower levels of annual sunlight are set beneath balconies. The balconies’ amenity benefits are considered to offset the associated reduction in sunlight. The rooms experiencing lower levels of annual sunlight will also receive good levels of internal daylight, as discussed at Section 4.0. Taking account of the proposed units’ generous balconies and good internal daylight levels, their natural light conditions and amenity standards as a whole will be appropriate.

6.11 The proposed units will therefore experience acceptable levels of sunlight both during the winter months and throughout the year.

7.0 Overshadowing 7.1 The effects of the development on the levels of sunlight experienced within the

neighbouring Valetta Grove Open Space and proposed areas of amenity space have been assessed. The following outlines the methodology and results of this overshadowing assessment.

Methodology

7.2 The BRE ‘test’ for a development’s overshadowing impacts relates to the area of an amenity space that receives more than two hours of sunlight on 21 March (the Spring Equinox). The guide states:

“…for it to appear adequately sunlit throughout the year, at least half of a garden or amenity area should receive at least two hours of sunlight on 21 March. If, as a result of new development, an existing garden or amenity area does not meet the above, and the area which can receive two hours of sun on 21 march is less than 0.8 times its former value, then the loss of sunlight is likely to be noticeable”.

7.3 The assessment has, therefore, considered the areas of amenity space that can receive more than two hours of direct sunlight on this date.

Results: Proposed Gardens/ Amenity Space

7.4 The results of the shadow analysis are summarised in the table below. The results are set out in full at Appendix 6.

Amenity space Area Lit area (%) Above/ Below BRE Guide Levels

Valetta Grove Open Space 5,906sqm 96% Above Open space A1: southern landscaped strip

303sqm 96% Above

Open space A2: Station Square public space

733sqm 63% Above

Open space A3: Roof level space above single storey café.

131sqm 68% Above

Open space A1: Northern amenity space

727sqm 27% Below

Open space A2: Park plaza public space

218sqm 93% Above

Open space A3: Fifth floor amenity space

514sqm 93% Above

Table 6.1: Summary of Shadow Results

7.5 The shadow analysis demonstrates that with the developments in place, the residual lit area within the Valetta Grove Open Space will remain at 96%. This is significantly above the BRE guide level of 50%. As such, the neighbouring park achieves the guide level. No other areas of neighbouring open space require assessment in terms of overshadowing.

7.6 Within the proposed development, five of the six areas of open/amenity space assessed will achieve the BRE guide level. This includes all of the spaces within the London Road site and the Park Plaza and roof terrace within the Valetta Grove site. The northern area


P16 13600635v1

of public realm within the Valletta Grove site will experience a lower level of sunlight owing to its location to the north of the development.

7.7 Overall, the results show that the development will contain a good range of well-lit amenity space and public realm.


13600635v1 P17

8.0 Summary and Conclusions 8.1 The assessment has considered the effects of the Plaistow Hub development at London

Road and Valetta Grove on the levels of daylight and sunlight received by nearby residential properties on Upper Road, London Road Juliette Road, Plaistow Road, Valetta Grove, Greenwood Road, Beardsfield, Opus Studios and Willow Lodge. Other buildings in the vicinity of the site are non-residential in use or are situated a sufficient distance from the site to be unaffected in daylight and sunlight terms.

8.2 The analysis also considers the levels of natural light that will be experienced within the proposed units and the effects of the development in terms of overshadowing.

8.3 Overall, the assessment has considered the effects of the development on daylight levels experienced by 191 windows serving neighbouring properties. 105 of these windows also require analysis in terms of sunlight availability.

8.4 Within the development, the assessment has considered the daylight levels that will be experienced by 323 windows and 171 main rooms and bedrooms, and the sunlight levels that will be received by 196 south facing windows.

8.5 Proposed areas of open space within the development and the Valetta Grove Open Space have been assessed in terms of the BRE two-hour sunlight contour analysis (overshadowing assessment).

8.6 The following summarises the development’s daylight, sunlight and shadow effects.

Daylight

8.7 The daylight assessment demonstrates that the development will not cause unacceptable effects in terms of neighbouring properties’ daylight conditions. The majority of the neighbouring windows assessed will either comply with the BRE guide levels for ambient daylight (VSC) or will experience only marginal effects as a result of the development. The results of the daylight analyses for neighbouring properties are good for an urban environment taking account of the flexible, suburban basis of the BRE guidance. It is, therefore, concluded that the development will not result in materially unacceptable impacts on the daylight levels of neighbouring residential properties.

8.8 The results of the daylight analysis for the proposed residential units within the development show that c. 76% and 96.5% of the proposed habitable rooms assessed will comply with the BRE guide levels for ADF and DD respectively. These are good levels of compliance with the guide levels for interior daylighting for an urban development project, particularly in terms of DD. The proposed accommodation will, therefore, experience acceptable levels of interior daylight.

Sunlight

8.9 The sunlight analysis demonstrates that all but five of the windows serving neighbouring properties that require assessment will comply with the BRE guide levels for annual and winter sunlight availability. These are isolated and marginal effects and the majority of neighbouring properties will retain good levels of sunlight with the scheme in place. It is therefore concluded that the development will not give rise to unacceptable effects in terms of the sunlight availability experienced by all neighbouring properties.

8.10 The sunlight analysis for the proposed residential units within the scheme demonstrates that c. 50% of the windows requiring assessment will achieve the BRE guide levels for


P18 13600635v1

annual sunlight. This is a typical level of compliance for an urban development project. Where lower levels of annual sunlight are experienced this is frequently attributable to the effects of generous balconies set above the windows and the rooms served by those windows experience good levels of interior daylight. Overall, the proposed accommodation will experience acceptable levels of sunlighting.

Overshadowing

8.11 The overshadowing analysis demonstrates that all but one of the proposed areas of open/amenity space within the scheme will experience high levels of sunlight. The Valetta Grove Open Space will also continue to comply with the BRE guide level with the scheme in place. The development is considered acceptable in terms of overshadowing.

Overall Conclusions

8.12 The results of the assessment demonstrate that the neighbouring residential properties and the proposed accommodation will receive good levels of daylight and sunlight following construction of the proposed development. While the assessment has shown that the development will result in some deviation from the BRE daylight and sunlight guidelines in relation to neighbouring properties and the proposed units and their gardens, these effects are mostly minor and are typical of urban development projects, having regard to the flexible, suburban basis of the BRE guide levels.

8.13 In conclusion, the proposed development will not give rise to materially unacceptable daylight and sunlight effects in the context of the BRE guidelines and relevant planning policy.
