Introduction

1

The aim of this report is to address

the Design and Detail of the project.

The project being a market built behind a

listed facade. The works to the facade and

the construction of the market building

will run in tandem with one contractor

(Paye) winning both tenders. The market

is separate building and is wrapped by the

facade.

The report will address the authors attitude

towards the site and the principle design

strategy.

The report will give an introduction to

the projects site context and the factors

that were taking into consideration during

the design process.

The report will be divided into 3 sections.

An introduction to the project consisting

oda brief introduction to what is being

proposed.

Section 2 will deal with the Design and

construction of the project it will give

a detail investigation to the principlebuilding fabric and material choices and

the process involved through manufacture.

This will be describe through annotated

diagrams describing the advantages and

disadvantages of the choices made.

Section 3 will outline the Design and

performance of the building fabric. It

will give a detailed analysis of how the

building performs in terms of the internal

environment. It will also address the

strategy for accustics, re, and daylight.

This will al be conveyed using annotated

diagrams to demonstrate the proposed

strategies. Any diagrams including the

forzen set of GA Drawings, and important

material not enclosed in the text will beinclude in the appendix.

The project from inception is set in 2009.

This is when the High street 2012 scheme

was initiated. Under the high street 2012

scheme it was set about to create a high

street that London could be proud of during

the Olympics as the this ribbon of road

from the city of London to Stratford was

high lighted as the returning leg of the

marathon to the Olympic stadium.

Although the decision in may 2010 that the

marathon was now not returning via this

link work still continued to enhance the

high street as it will still be used a the

major route for ofcials and spectators to

the Olympic site.

These Group of building were selected in

march 2009 for rejuvenation of the facade.

But due to the monumental disrepair of the

building itself it was proposed that and

building tting of this new regenerated

area would be commissioned, to work with

the restored facade.

With high street 2012 as the client for

the project and working closely with them

after appointment in July 2009 a building

tting to the area and paying close

attention the community plan for the area

was proposed. Taking the form of a market

an extension of the high street if you

like set about a designing challenge with

a tight construction period with denitive

end date in mind.

building have been selected for restoration

under the high street 2012 scheme. The

building are of historical interest and have

fallen into state of disrepair due to years

Site Orientation

The orientation of the building is facing

north and as shown is shadowed by the

surrounding building to the south of the

site. This will have to be addressed in

the design as gaining light from the roof

will be paramount to give the space as

much natural light as possible.

Design and Detail

The Listed Facade

As the work taking place on 64-68 Whitechapel

High Street is within the Whitechapel High

street Conservation area implemented in

1997 to preserve what is left of the old

building stock in the area.

When High Street 2012 announced its plans

for 64-68 Whitechapel High Street, Tower

Hamlets and English heritage Awarded

a grade II Listing to the facade when

restoration works are complete.

Due to the listing on the facade works

being carried out will have to pay

particular interest as clauses with in the

listing state that the facade cannot be

penetrated.

This will create a serious design

constraints when design the structure

and for M&E Services. Close attention to

these elements and an alternative will

have to be sought. Due to the building

behind being independent of the facade.

Careful attention to detail to protecting

the facade and how it is propped and

structurally reinforced will have a strong

inuence on the design. Strong detail

design will take place in order to achievea method of facade retention.

Legal Issues

Site Boundary

High Street 2012 in February 2009 imposed

a compulsory purchase order on 64-68

whitechapel High Street as it was deemed

the owner had allowed the building to

degenerate due to years of neglect.

The legal boundaries obtained from the

Land Registry shown below outline the

legal boundaries of each of the buildings

within the block.

The new proposal seeks to amalgamate allthese boundaries into one complete site

generating one building within the new

site boundary.

As shown in the diagram the site is like

a peninsula accessed on three sides. The

fourth edge is the party wall with 69

Whitechapel High street and this will

conjure up legal terms to be adhered to.

The architect will have to issue a 3 metre

notice to the owner/occupier of this plot.

Other consideration will be the rights of

way and safety to pedestrians. The close

proximity to the High street will call for

TFl to be notied. Demolition works will

also call for TFL to be notied due tothe proximity of the underground railway

network.

Design and Detail

Party Wall

64-68 Whitechapel High Street has a legal

boundary with no.69, This in turn will

engage The Party Wall etc. Act 1996. A 3

metre notice (see Appendix)of works will

have to be issued before construction.

As the works to be carried out will involve

new foundation and the raising of the

mass to match the existing mass of the

front elevation it is deemed necessary to

construct a new Party wall.

To over come this a notice will be issued

under the service Work to Existing Party

Wall. The time frame for service of notice

for such works will mean a notice issued

2 months prior to work commencing on site.

The contents of the notice will entail:

Name and address of Building owner Proposed works, including the foundation

requirements and will be accompanied

with a full set of planning drawings

to convey the works to be carried out.

The Notice will also outline the proposed

start date for work to commence.

Problems may arise if the Adjacent owner

serves a counter notice within 1 month

requesting work to be carried out. The

building owner must comply. But if the BO

does not consent within 14 days a period

of dispute will be entered. Due to the

denitive end date for works this will at

all cost avoided unless the counter notice

has unreasonable demands.

7/31/2019 D&D Final

12/45

Due to the proximity of The Site to adjacent

building provisions under section 6 of the

Party Wall Act etc. 1996 will have to be

enforced.

As the existing building is to be demolished

and site works including excavation to the

basement will take place a 3 metre notice

will have to be issued, not just to no.69

but also to no.s 5 - 9 Whitechurch Lane and

to London Metropolitan university Central

House as these all fall within 3 metres of

the site. Also TFL will have to be issued

with this notice due to the proximity of

the Access to Aldgate underground station.

This notice will have to be issued in

relation to building adjacent to the site

with a 3 and 6 metre radius.

The service time for such notice will be1 month.

The notice will have to contain all

details regarding excavation and include

the Depth and position of the excavation

to take place. This notice will have to

be accompanied by a full set of planning

drawings outlining all the issues.

They will also have to show a set of

setting out drawings in relation to the

proposed structure.

The excavation works and demolition works

will all have to adhere to Tower Hamlets

COCP.

Programme:

After the completion of the Compulsory

Purchase order High Street 2012 engaged

with the Architect to address the notion

of programme. Speed is of the essence as

there is a denitive end date that of the

London 2012 Olympics.

Client through tender appointed the

architect and the design team consultant

and each then set about adopting the

programme.

The Programme for the proposed building

behind the facade is to create multiuse

retail spaces with competitive rental

rates with that of the newly refurbished

Whitechapel market. The programme also

working closely with London metropolitan

university will seek to set aside retail

pitches for design students to utilise

as a start up space for entrepreneurial

pursuits.

The basement of the building will house

an exhibition space with associated Audio

visual equipment giving the building

another purpose and allowing it to be

utilized by different community groups for

specic venue requirements.

As one of the existing tenants of the

building is a cafe, provisions will be

made to accommodate this business within

the design with consultation with the cafe

owner in relation to layouts and specic

kitchen and storage requirements.

Proposed Scheme Concept

Vertical Circulation

Plug in Units

Plug in Units

The concept is to have a range of plug in

units arranged around a ramp that climbs

through the building.

The Ramp and the external new shell have

structural implications. They help without

the need for buttressing the front facade

in keeping it upright.

The Restored facade acts merely as a

wrap for the building the public face

the internal spaces will be in complete

contrast to the external appearance.

The concept Behind the design is to create

a form with multiple functions.

Taking inspiration from Cedric Prices Fun

Palace the building I want to achieve is a

multi- function community hub.

that visitors can gain information about

the building and where security will be

present. It is from the ground oor where

the visitors can nd the circulator ramp .

The ramp lets the customer ascend through

the building to the multiple retail units

through out the building and the bar/

restaurant on the third oor.

Located in the basement is the back of

house spaces consisting of the Kitchen

that services the cafe and the Restaurant

via a dumb waiter that is situated nest the

riser.The administrative ofce are alsolocated in the basement oriented again

light through light wells located in the

pavement above.

The ramp is a concrete self supportive

structure that spreads the load to the

slab. Its is precast and lowered into

place on site.

The remaining Structure is steel, with astructural frame in place to prop up the

front facade.

Structure

The Structure of the market building is a

mixture of in-situ concrete and structural

steel frame. The Steel frame was chosen

due the site constraints and it can be

easily manufactured of site and craned

into position and bolted together.

The steel frame then enables the oor

slabs to be lowered into place.

The ramp is an independent structuremanufactured of site as one reinforced

concrete element. It is design to be self

supporting and spreading the load to the

slabs at its connection point.

The structure rest on reinforced concrete

piling this method of foundation was chosen

due to the soil quality of London.

Rear Facade Construction

Litra Con

Litracon is a combination of Optical Fibres

and ne concrete. it can be produced as a

prefabricated building blocks and panels.

Due to the small size of the bres,

they blend into the concrete becoming a

component of the material like a small

piece of aggregate.

Thousands of optical glass bres form a

matrix and run parallel to each other

between the two main surfaces of eachblock.

As load bearing structures can be built

using these blocks, as the glass bres

do not effect the comprehensive strength

value of the concrete.

So as to continue on the movement them

within the design the use of these block

on the facade on to whitechurch passage

will be utilised.

Because the block become translucent the

movement behind the facade will be evident

along the passage it will also act as

beacon lighting up the dark passage way.

This material was chosen as its quite cheapand an alternative to a mass of concrete

and will give the rear facade a nished

feel at the same time allowing the public

to see what is going on in the building.

Litra Con Prototype

A prototype was constructed to test weather

this method works. From the model made

it clearly demonstrates the translucent

quality of the concrete.

Using foam board as form work bre threads

were stitched trough forming a tight weave

then the ne aggregate mixed concretes was

pored in and let go of and set. the result

with a light behind it makes the concrete

seem translucent.

Heating

The building is heated via a ground source

heat source pump that is constructed when

with the pile foundation.

The restoration works to facade has created

a cold bridging problem as the facade is

only being glazed using single pane sash

windows.

Taking this into consideration and this

being market the space will be left to

rely on the ground source heat pump. theregulation of temperature is not really an

issue as the building faces north so no

much heat gain in summer via the glazing.

Fire Strategy

As the building is an open volume the re strategy is an

important.

The occupancy load factor which is measured by the number

of people per square metre states that in a commercial

building the number of people is 6.

Taking this into consideration and examining travel

distance.

In a commercial building for stage 1 evacuation it is set

at 40 meters in the market a no point with the building areyou more than 20 metres from the escape route this also

takes care of stage 2.

The escape stairs provided are to a size conducive the

O.L.F and distance.

A down turn in the slab creates a curtain to help prevent

the spread of smoke up through the building.
