Peckham, London

£180,000

A private house on a brown field site between existing domestic properties presented us with some unique buildability issues. Due to

acess limitations, all elements had to be brought through a narrow 2.4m wide access from the main road.

The selected structural scheme maximised the width of the site by tying in the existing boundarys without disturbing their Victorian

footings. The structure was then constructed using two steel frames for stability and then simple loadbearing walls. The large floor spans

were achieved by using lightweight timber ’I’ joists which could be handballed onto the site

This project presented a number of challenges for the team. As with any refurbishment project we worked hard to discover how the

existing building was working before we presented solutions to modify it. Along with the existing building investigations, we completed

a comprehensive site investigation to assess the ground conditions on this sloped site. Both the building and site revealed a number of

surprises once analysed fully which went on to heavily influence the final solutions.

We worked to produce a number of schemes at an early stage and illustrated these in sketch form to discuss with the Client. This allowed

both the Client and the Architect to be fully engaged in the structural process and to provide a well coordinated and coherent scheme.

Midway down a single track lane, this woodland retreat presented us with both access and buildabilty issues. Our structural solution had

to allow for small elements to create a larger whole. With a 15m clear span and the inability to get a significant crane to site we looked

hard at the buildability and sequence of construction to inform our solution.

The site constraints lead us to a standardised element with a standardised connection detail which allowed us to create a storey high

Vierendeel truss which sat comfortably within the zones created by the architecture. With all the structure exposed, understanding the

construction tolerances and the sequence meant we were able to develop a series of simple yet effective details to ensure crispness of

finish whilst maintaining ease of build.

We worked closely with our Architect here to produce a fully integrated structure with the lighting. We proposed a structural scheme

which allowed LED lighting strips to be inserted within the structural support fins. We were able to minimise the weight of the structure by

creating a hybrid form which uses the glass for stability. The frame was pre erected off site to ensure build quality and speed of erection on

site.

Cantilevered rear structure Steel portal frame redistributing the loads

This project required some integrated temporary works and clear understanding of the building process. The rear two storey structure

in the rear elevation was required to hover above the glass rear extension. We achieved this by using the mass of the main structure

and cantilevering two steel beams out to pick it up. By inserting a new raft below the building, we were able to redistribute loads evenly

eliminating any differential movement.

Cross Laminated Timber Construction


Situated on a narrow site with both width and height restrictions keeping the structural elements to a minimum was paramount. We

decided to proceed with a cross laminated timber construction which allowed us to maximise space and minimise construction depth. The

structure will be built in 3 days providing a platform and watertight environment from an early stage.

Curved Roof Overhang

As part of Kingston’s Primary Capital Programme we have worked with the design team to provide the school with 9 new classrooms and a

new dining hall structure. The site is surrounded by a number of mature trees and bounded on one side by the railway. These constraints

meant understanding the build sequence was an important part of the design process and a combination of minipiles and regular piles

allowed us to negate the issue of both the trees and the railway whilst retaining a quick and economical build. The conical roof of the

classrooms was created using a series of simple radial timbers in Kertolam timber which allowed the beams to be installed in one complete

length. The dining hall is constructed using an exposed glulam timber frame which provides a column free and attractive double height

space.

Vibro Stone Column Concrete Pads To Support Modules

This project combines a new dining facility for the school and a new children’s centre. Due to the need for the children’s centre to be at

ground floor level, the larger dining area overhangs, creating an interesting structural form. We have used pre-fabricated modules to ensure

a swift build whilst minimising costs. In addition to the modular build, we have used simple ground improvement techniques to reduce

foundation costs.

We are currently working on the scheme for a new sports and entertainment complex at the Harrodian School in Barnes. The school is on

the site of the Former Harrods Sports Club and the original premises have been extended and converted for educational purposes. The

scheme involves sinking the building into the ground to allow the facility to present a minimal elevation to the surrounding properties as the

site is situated on Metropolitan open land. We have completed an extensive desk top study in conjunction with our Geotechnical consultant

to attempt understand the ground conditions as the site is close to a former reservoir and the banks of the Thames. The project is currently

in planning and we hope to begin work on the final scheme in 2012.

The Client came to the design team with a tight site and a need to expand whilst mantaining operations. The Client also had a very hands

on approach to the works but little experience with building.

The existing portal frame shed was erected in the 1970’s on the site of a V1 rocket strike. We came up with a scheme which punctured

the existing structure whilst leaving it mainly unaltered. This gave us the ability to extend the existing footprint within the site boundary

whilst the structure remained 80% occupied. In puncturing the existing structure, we were also able to reuse the existing envelope further

reducing costs.

We worked hard to communicate the structural decisions and processes to enable the Client to engage in the process. This allowed the

structure to influence the design of the building providing a balanced and integrated end product.

The screen is formed of 11 frames that come to site prefabricated with the Microcables already attached. Each frame has 2 rows of 2.5mm diameter Microcables supported top and bottom that are arranged in a rhythm of colour. The top member is bolted to steel channel that is already fixed in place prior to frames coming to site. The bottom member of the frame is bolted to the existing balustrade which is cut down in height and the cables are tensioned in sequence to the correct tension. The wires can easily be replaced if required.

Located in Shoreditch, this mixed use development posed some interesting buildability issues within the fabric of this Victorian industrial

unit. After providing a condition survey of the existing building, we worked on producing a structural scheme for a 2 storey roof extension

which respected the existing structure. Small elements were used to create a larger whole ensuring all elements could be brought through

existing doorways. This provided an economical and traditional build which suited its setting and the type of contractor who would carry

out this scale of work.

Conversion of an existing basement and ground floor office space of a 4 main storey building into a restaurant. The works involved the

removal of various internal load bearing masonry piers at each level, replaced with an arrangement of steel beams spanning onto the

existing party walls in order to provide a column free interior space. The new steels were either kept short or spliced to aid delivery of

these to site, undertaken through a standard doorway.

One of the main internal piers removed at ground floor level was heavily loaded - support to this load was provided using a double height

steel goalpost frame, bearing on a new mini reinforced concrete raft founded at basement level.

A Thames Water trunk sewer runs directly below the buildings at the southern end of the site and a Victoria Line underground tunnel runs parallel to the western boundary of the site and partially under the north end of the site.

Given the constraints around the site, the largest part of the structural work was in designing substructures that would carry the building loads, provide the required areas of basement parking and were affordable for the client and acceptable to the three principle statutory authorities.

The substructure proposals used a combination of sheetpiling, bored piling, reinforced concrete rafts and transfer beams to ensure that the optimum design solution was used. In analysing and designing the superstructures, Packman

Beechmore Road Perspective

Site Overview

We are currently involved in producing a structural feasibility report for this new mixed use residential and retail development. In working

closely with the other consultants at this early stage, we are able to offer the client an added value building which represents the integrated

design approach.

Our main input is to consider basement construction techniques which maximise space whilst moderating cost. This issue will be the

difference between a single or double storey basement carpark which will dramatically effect cost.

Part of the Masterplan to redevelop the Bridge House and Marion Court estate off Hommerton High Street, Hackney. This project has all

the classic constraints of an East End site along with the additional problem of being located over the new Chelsea to Hackney Crossrail

line. Lyons O’Neill are currently developing the foundation options to give the Client the ability to understand the technical issues and to

make informed decisions on how best to progress the scheme. Along with the detailed design Lyons O’Neill worked on the desk study for

the site including a historical and UXB search.

The scheme is due on site in late October 2010.

This project involved us working in partnership with a local developer to maximise the usable space on the site of a disused public house.

We looked at various methods of construction to both reduce time on site and the amount of spoil removed. Consideration of heave issues

at an early stage allowed us to programme works permitting heave pressures to relieve during the Christmas break. This allowed us to

remove the anti heave piles below the basement raft reducing both costs and programme time.

Drayton Park








An existing brownfield site situated between Drayton Park road to the east and railway lines and the Emirates stadium to the west was

redeveloped to provide 225 residential units. The reinforced concrete framed residential blocks are up to six-storeys in height, with the

majority underlain by a single level basement car park.

A Thames Water trunk sewer runs directly below the buildings at the southern end of the site and a Victoria Line underground tunnel runs

parallel to the western boundary of the site and partially under the north end of the site.

Given the constraints around the site, the largest part of the structural work was in designing substructures that would carry the building

loads, provide the required areas of basement parking and were affordable for the client and acceptable to the three principle statutory

authorities.

The substructure proposals used a combination of sheetpiling, bored piling, reinforced concrete rafts and transfer beams to ensure that the

optimum design solution was used.Kevin Lyons engineered the structure whilst a Director at Packman Lucas

Simple cable tensioning springs

7m high carbon fibre gullwing doors The gallery space

Viewed from both within the gallery and from the balcony above, the structure has the opportunity to present two faces. The structure is

essentially all external allowing the internal space to be free of obstruction and ultimately flexible to the curator.

The lightweight box is achieved by suspending the roof members with a series of 1.5mm diameter cables from a simple frame hidden

within the roof lantern. This allowed us to maximise the structural capacity of the sections creating a simple but elegant roof. The cables

were individually positioned through holes in the roof level frame and tied together before constructing the box. Once installed the cables

were draped and pushed through individual clutches to support the roof. Small springs were introduced to the cables to ensure tension was

always present even with variation of loading and construction tolerances. The installation process was prototyped to develop a sequence

of working which allowed the structure to be delivered within programme and budget.

The entrance to the space creates a transitional lobby where a perceptual shift from the V&A proper to the Contemporary program is

allowed to occur. It has been designed to offer different forms of access to the gallery through five seven-metre high rotating screens.

The screens can be reconfigured to the curatorial needs of each exhibition and are clad in reflective black carbon fibre sheeting, a very

lightweight skin more commonly found in aircraft manufacture.

Lyons O’Neill have been shortlisted along with 4 other practices for a new installation in the heart of the City. The sculpture marks a part of

London’s High Street 2012 initiative and will remain in place for the duration of the 2012 Olympic Games. It will stand on a site historically

known as ‘Ale-Gate’, so called because it was the only City gateway open to all. It is hoped the new landmark will underscore the fact that

the City now welcomes, rather than drives away, its neighbours.

We responded to both the temporary nature of the installation and the congested nature of the site by introducing a light touch structure

which can be installed using the minimum of plant and without closing the road. This fully interactive installation can be simply demounted

leaving the site exactly as it was and can easily be reinstalled in another location as a more permanent piece.

This was a winning scheme for the RIBA competition for a set of Kiosks at the entrance to Stratford Station. This Olympic project required

the kiosks not only to perform as a functioning retail unit but also provide a sense of space and for a portal for approaching spectators.

We used a combination of Reinforced concrete and CLT Panels to form this panalised building. The concrete base was extended up to

form a robust skirt and which also acted as a security barrier to the station and the buses which entered the adjacent station. The CLT

panels allowed the structure to be quickly assembled in the space as well as providing a self finishing structure. The use of screw piles for

foundations meant the structure is completely demountable if required.

Basement

Ground Floor Construction

This two storey basement in an in fill site between a number of properties presented a number of challenges. Understanding the context

of the building in relation to the boundaries was key on this project. Having around 20 party wall awards a robust and consistent approach

was required as well as clear and informative drawings. A combination of traditional and innovative grouting techniques were used to

stabilise the ground and retain water during the works. Monitoring stations with trigger levels were agreed with the boundary Engineers to

ensure works progressed safely and without disruption.

Lyons O’Neill - Boundary Wall Section Details


Many local authorities now require pre planning structural reports when considering basements. We have produced a number of these

reports and developed a report style which focuses on the process as much as the solution. This is to inform both professionals and lay

Clients our key decisions and to inform the planners of the viability of the scheme.

Site Construction - RC Capping Beam

Architect’s Section

This basement was located on a sloped site with some unique geotechnical issues. Being almost at the natural slip angle for London Clay,

stabilisation of the slope during the works was a key element of the works. Being able to illustrate the issue to the team and Client meant

that the position of the of the swimming pool was altered to provide a much cheaper retaining structure. This process of illustrating possible

solutions meant the Client had an understanding of his building and was able to make informed decisions on the structure. We looked

closely at the build process to help drive out key cost items and to enable party wall awards and planning to be easily achieved.

Temporary Propping Of Existing Ground Structure While Excavation Occurs Steel Frames In, Basement Slab Under Construction

This project required us to tunnel under an existing building whilst the Client was still in occupation. We investigated the build process

through drawing to come up with a permanent structure which also was used as the temporary works. We came up with a series of frames

which were introduced at 1.2m centres on mass concrete bases and underpins. Once these were installed and the slab supported, the

beams were spliced allowing a number of temporary columns to be removed and the spec opened up.

A more straight forward single basement construction and typical of a number of residential conversions. We looked at the build sequence

here and established it would be cheaper to rebuild the rear extension rather than retaining the structure which was proposed by a previous

Engineer. The savings on temporary works allowed the Client to extend the basement providing greater value a much more usable space.

Again this project required a pre-planning report and construction method statement which we provided at an early stage allowing for a

Lyons O’Neill Drawing - Section

We continued our work with the Big Basement Company on this 2-Storey basement on a constricted site in Chelsea. The scheme called

for demolition of the structure whilst only retaining the facade which presented a difficult set of temporary stability scenarios. We worked

closely with the Big Basement Company to come up with a sequence of construction which allowed the permanent floor structure to act as

both temporary and permanent works. This created a saving not only in cost of temporary works but also in time on site. The construction

sequence was illustrated to both investigate and explain the process and was used as part of the party wall submission accelerating the

process.

The high water level in the area meant we adopted a hybrid foundation solution to maximise the space available to the client whilst

maintaining stability of the surrounding structures. The solution involved a traditional underpin to the upper basement level which allowed

a full width basement and then progressing to a secant mini-piled wall solution below the water table. This secant piled retaining wall

structure penetrated into the clay strata below the site which allowed us to excavate below the water table in dry conditions.

Our challenge on this project was to create a complex 3 dimensional form with simple 2 dimensional elements. The centrepiece of the

scheme is the ‘Boiler Suit’, a facade surrounding the boilers that power the hospital. The final facade is formed of 108 tiles made of 40km

of woven stainless-steel braid.

At night the Boiler Suit is illuminated ‘to provide a distinctive welcoming beacon for staff and visitors arriving at the hospital’.

The scheme also includes widened pavements, a one-way traffic system with designated drop-off points, new signage, CCTV, lighting and

a new build shop.

The project has been funded by the Pool of London Partnership, Guy’s and St Thomas’ Charity and the Friends of Guy’s Hospital.

We are currently working on the scheme for a new sports and entertainment complex at the Harrodian School in Barnes. The school is

on the site of the Former Harrods Sports Club and the original premises has been extended and converted for educational purposes. The

scheme involves sinking the building into the ground to allow the facility to present a minimal elevation to the surrounding properties as the

site is situated on Metropolitan open land. We have completed an extensive desk top study in conjunction with our Geotechnical consultant

to attempt understand the ground conditions as the site is close to a former reservoir and the banks of the Thames. The project is currently

in planning and we hope to begin work on the final scheme late in 2011.

It should feel slightly daring to be in this space; not dangerous but a definite shift from normality, a juxtaposition of the familiar pushed into

a new context. Uninitiated onlookers will wonder what it is at first: purely a sculpture or something more? On their daily commute they can

see how it changes in the light: reflecting conditions and giving new perspectives. They will become aware it is occupied which can only

add to the intrigue. Guests will become more comfortable over time as they absorb their new surroundings. Initial concerns about exposure

give way to the possibilities offered by their temporary home. How often will you get to lie in bed as the sun rises over the London skyline

all around you? Or lie in darkness and observe the city at night?

Hansom Cab, London

The Hanson Cab

Lyons O’Neill were commissioned to produce a condition report on this grade II public house constructed in the early 19th century. Our

study soon revealed that the structure, which appeared to be uneconomical to refurbish, could be made robust by some simple yet

effective remedial measures. This allowed our client to purchase the building with the confidence he could redevelop the residential space

above.

As part of the refurbishment work we developed a structural scheme which allowed a new access to the flats and toilet facility to be

created for the pub whilst it still operated. This was achieved by forming a lightweight structure which spanned across the roof of the

kitchens to the pub sitting purely on the external walls. The link between the pub and their new facilities will be switched over during a

fortnight of light refurbishment works to the pub allowing maximum trading time.

Architects Plan


This was a winning scheme for the RIBA competition for a set of Kiosks at the entrance to Stratford Station. This Olympic project required

the kiosks not only to perform as a functioning retail unit but also provide a sense of space and for a portal for approaching spectators.

We used a combination of Reinforced concrete and CLT Panels to form this panalised building. The concrete base was extended up to

form a robust skirt and which also acted as a security barrier to the station and the buses which entered the adjacent station. The CLT

panels allowed the structure to be quickly assembled in the space as well as providing a self finishing structure. The use of screw piles for

foundations meant the structure is completely demountable if required.

Lyons O’Neill sequence of construction sketch



Our aim was to provide a simple form which respected the low lying setting and did not dominate the horizon. The site’s geology means

that the West bank has better founding conditions than the East pushing us towards a solution supported from one side only. After drawing

up various options it became clear that completely supporting from one side would provide too dominant a form which was something

we were working against. As a result we looked at a simply supported solution and tried to refine them to provide a slender elevation. We

settled on a simple parallel chord truss form and worked to reduce its elevation. To improve its depth we introduced a column on the West

Bank to balance the bridge’s forces and allow us to present a slimmer elevation. The form is tried and tested and is made up from simple

elements requiring low levels of fabrication. To reduce the dominance of the structural members we further refined the truss by using the

longitudinal cladding to laterally restrain the main members against buckling. This will allow us to further reduce their cross section and

therefore the bridge’s weight and cost.

Competition

Aldgate, London

Not Disclosed


Lyons O’Neill have been shortlisted along with 4 other practices for a new installation in the heart of the City. The sculpture marks a part of

London’s High Street 2012 initiative and will remain in place for the duration of the 2012 Olympic Games. It will stand on a site historically

known as ‘Ale-Gate’, so called because it was the only City gateway open to all. It is hoped the new landmark will underscore the fact that

the City now welcomes, rather than drives away, its neighbours.

We responded to both the temporary nature of the installation and the congested nature of the site by introducing a light touch structure

which can be installed using the minimum of plant and without closing the road. This fully interactive installation can be simply demounted

leaving the site exactly as it was and can easily be reinstalled in another location as a more permanent piece.

Construction Site With Perimeter Temporary Works


Phoenix Community Housing is a not-for-profit resident-led Housing Association in the Bellingham, Whitefoot and Downham area of

Lewisham, London. Properties were transferred from Lewisham Council in a large-scale voluntary transfer on 3rd December 2007 following

a positive ballot of all tenants. It is a new organisation, developed for this area, and has no connection with any other Housing Association.

On winning the framework bid Lyons O’Neill met with PCHA to discuss their brief and to determine whether there were any items we could

expand on which we could add value too. We quickly establish a need to take a global view of PCHA’s properties and database of issues.

Little information regarding the properties was transferred with the sale from Lewisham so PCHA were essentially starting with a clean slate.

Most of the properties sent through were suffering from movement and damage as a result. On receiving the first batch of properties to

review we undertook a desktop search on the properties to see if there were any environmental or historical land issues that may have been

an issue. It was quickly established that the majority of the properties were situated on Clay which instantly pointed to shrinkage and heave

issue. In addition to this our historical research showed that the properties in the main were constructed as part of the ‘Homes for Heroes’

programme after the first world war.
