Tonkin Liu wins RIBA Stephen Lawrence Prize 2018

  • Comment

The practice’s ‘breathtaking’ conversion of a disused farm shed in North Yorkshire into a sustainable house has been announced as the winner of this year’s RIBA Stephen Lawrence Prize 

Old Shed New House was revealed as the winner of the £5,000 award, which recognises the UK’s best projects built for less than £1 million, at the RIBA Stirling Prize party held at the Roundhouse in Camden tonight (10 October).

The 210m² project was built for the parents of project architect Greg Storrar, who had been searching for several years for a quiet rural site to build a home for them retire to.

The three-bedroomed property includes a vast library at its heart – housing a lifetime’s collection of books – and uses traditional construction techniques and low-cost materials throughout.

Judge and founder of the Stephen Lawrence Prize founder Marco Goldschmied said: ’This impressive project has brought life back into a redundant agricultural building to create a breath-taking new home.

’Using sustainable, low-cost materials, Old Shed New House illustrates perfectly what a talented architect can do with a fairly modest budget.’

Tonkin Liu saw off shortlist competition from seven projects including Belvue School’s Woodland Classrooms by Studio Weave, SKArchitects’ hostel for vulnerable homeless women and 31/44 Architects’ precast concrete-clad Red House.

The judges also gave a special mention to and an award of £1,000 to the Bethnal Green Memorial  by Arboreal Architecture, built in tribute to a little-known World War Two tragedy. 

Last year the accolade was taken home by The Houseboat in Dorset, designed by Mole Architects in collaboration with Rebecca Granger (see AJ 31.10.17).

In addition to Goldschmied, the judges for the 2018 Stephen Lawrence Prize were Baroness Lawrence of Clarendon, Doreen Lawrence OBE, the mother of Stephen Lawrence; Meredith Bowles, of Mole Architects and Stephen Lawrence Scholarship recipient Asher Bourne. 

Previous winning practices include Duggan Morris (2012), Alison Brooks Architects (2006) and Cottrell & Vermeulen (2002).

Judges’ citation  A beautiful special gem of a building, which reflects the success that the ambition, determination and talents of a client and architect working creatively together can achieve when they share a vision for creating a better world. Belvue School is a secondary school for those with severe learning difficulties and a range of other needs. The school sits next to a small scrub of land with a few trees, shrubs and undergrowth. Although small in extent and hardly luxurious in planting, nonetheless it represented a glimpse of nature with which the pupils, who mainly live in blocks of flats nearby, were otherwise unfamiliar. The school was to be allocated two site cabins  to meet its need for more space but the head teacher decided that her pupils deserved better than that. She realised that, through design, a much more imaginative solution could be found that would provide a rich and stimulating learning environment for her students. To achieve this, she raised the money for the building independently and so the design direction was under her control and not hidebound by institutional limitations.

Her brief was to create 150m² of extra-curriculum space, with a domestic quality and intimate scale. Studio Weave developed a collective narrative with the pupils to open up imaginative ways of engaging with the outside. Through a series of story-writing and design workshops, the boundary between the playground and wood was identified as the border between familiar school territory and the magical mysterious world beyond, with the new Woodland Classrooms acting as the gatehouse and gateway to this magic world. The result is a wonderful, beautifully organised building, with an almost temple-like quality. A central open, covered space frames the wood, exactly as a gatehouse should, but it also has a tent-like outdoor quality. At either side are two rooms: one cosy with a wood-burning stove, the other fitted out as a kitchen and dining area to help students develop independent living skills. The building has an exposed timber frame and is lined in birch plywood.

Every school should have a retreat like this

The roof is an extremely elegant series of three formed roofs, with clerestory lights, that illuminate its very beautiful profile, while also allowing a straightforward stack effect for natural ventilation. Every detail of this building has been carefully considered and crafted. There are shelves for things students have made, cosy corners and student-made tiles as a splashback to the sink. Every effort was made to involve the students, to the extent that health and safety regulations would allow. This building is a labour of love, which sits lightly on the ground. It is naturally ventilated, thoughtfully orientated to maximise sunlight and avoid overheating, fully wheelchair accessible and all the timber is from reliably renewable sources. The playfulness and ingenuity of this design are apparent at every turn, epitomised by the unique weather vane on the rooftop, twisting in the wind. Every school should have a retreat like this, where students can go to connect with nature and be themselves. And, at less than £250,000, they can probably all afford it.

Bethnal Green Memorial, London, by Arboreal Architecture

Date of completion December 2017
Client Stairway to Heaven Memorial Trust
Contract value £457,000
External landscape site area 98m²
Cost per m² £4,663
Contractor Coniston

Judges’ citation  In 1943 one of the worst civilian disasters in modern British history occurred in what is now the south-east access stair to Bethnal Green Underground station, used at the time as an air raid shelter. In the accident, 173 people, including 62 children and babies, were crushed and asphyxiated to death as they rushed to gain shelter during an air raid. With more deaths than the 1966 Aberfan landslide, and 1989 Hillsborough stadium disaster, it is surprising so few know about it to this day. An official enquiry was held days after the disaster but was kept secret until after the war.

Despite censored press reports at the time, those involved were told by officials not to talk about it and the story was suppressed for fear of undermining the war effort. In the absence of the truth, rumours spread that a German bomb had landed in the stairwell, which was convenient accidental propaganda and was allowed to prosper.

In 1945 the enquiry report was released, however, the witness statements and various documents, including those outlining requests to the Home Secretary to improve the safety and condition of the stairwell before the disaster, continued to be classified and were only recently made public.

Many of those directly affected by the incident, partly due to the authority’s reaction, and partly due to the terror and trauma of the experience, suppressed the event, never talking about it, even to their families. In 2006, 63 years after the event, Harry Paticas, a Bethnal Green architect, noticed a plaque that had been discretely fixed to the stair in 1993 quietly acknowledging the deaths. After some research, he felt strongly that a more fitting memorial was needed that would better acknowledge the tragedy for those who were killed, their families and those who survived.

What followed was an 11-year labour of compassion involving research, investigation, revelations, meeting victim’s families and survivors (some telling their story to their families for the first time), the emergence of a charity client to raise money for the project in 2008 (Stairway to Heaven Memorial Trust), charity tin rattling, political lobbying, negotiations with TfL (their stairwell and tunnels below), Thames Water (water main below), statutory authorities (gas and electric main below), design, structural co-ordination, further negotiation with TfL, further fundraising eand so on. The concept for the design is that of an inversion of the negative space within the stairwell where the crush occurred, lifted up and to one side of the stairwell in the corner of the park. The hollowed-out negative stairwell is built from sustainably sourced solid teak with cone-shaped holes in the roof that at midday throw a light shaft toward the stairwell where the tragedy occurred, one for each life lost.

The project wouldn’t have happened without the architect going way beyond the extent of simply ‘doing his job’

A polished concrete plinth supports the teak inverted stair and folds across the site with multiple bronze plates fixed to it with extracts from the accounts of survivors and victim’s families. The plinth twists and leads to a bench where those who have just read the accounts can pause and reflect. The outcome, 11 years after Harry noticed the small plaque, is a striking memorial that is part sculpture, part architecture and that has conceptual rigour, a poignant justification for its form, a clear consideration to the viewer’s experience and spatial interaction, a construction and structural complexity, and is built to an impeccable level of finish and detail.

The project would not have happened without the architect going way beyond the extent of simply ‘doing his job’. He created the project from nothing, he researched and established his brief, he discovered the people who he would need to be the client, he helped the client to fund raise and shake tins, he engaged in complex negotiations with multiple parties one would normally have to do for a significant building (and significant fee); he found a way to achieve the memorial and succeeded.

Dartmouth Park House, London, by AY Architects

Contract value Confidential
Internal area 216m²
Cost per m² Confidential
Contractor Re-structure JC

Judges’ citation  Beginning as a modest conversion of an over-developed Victorian terraced house, the project became an ambitious redevelopment of the entire building. By reflecting the client’s personal travels and interests, AY Architects has created an unusual and exotic home.

The process of opening up the building to let in daylight has created a series of light, airy spaces linked by a courtyard, staircases and terrace. A 9m-high, three-floor void is a spectacular intervention containing a white-steel and mahogany staircase with crafted balustrade, extending from the basement to the second floor in a series of straight flights, curves and bridges. The ground floor has mahogany shelves and bespoke furniture, which fit well with the reclaimed oak parquet floor and leads to the timber-floored internal courtyard. This connecting space acts as an outdoor room with a centrally placed tree fern providing shade. The guest bedroom and bathroom extension on the opposite side of the courtyard is given privacy by the use of structural hardwood screens which were prefabricated, partially assembled and shipped from Nicaragua (a connection from the clients’ travels) giving a warm and consistent timber finish and unifying both internal and external areas of the house.

The upstairs terrace, with views of neighbouring gardens, sits above the guest bedroom and is linked by the main staircase to the house and circles around the courtyard to a staircase to the kitchen. On the second floor the walls and ceiling of the master bathroom are stripped back to reveal the original brick and timber of the building and is lit by a skylight. Lastly, the basement office has a light well from the courtyard and a walk-in shower, which is beautifully finished in stone. From the street, the former shop front is discreetly painted grey, with smoked glass concealing the theatricality of the interior. It is a very successful reinvention of the Victorian house.

Five Acre Barn, Aldeburgh, Suffolk, by Blee Halligan

Date of completion March 2017
Client Five Acre Barn
Contract value Confidential
Internal area 450m²
Cost per m² Confidential
Contractor Paul Rolph

Judges’ citation  The Five Acre Barn is an original building form that is well-suited to this new type of brief. The scheme provides new build bed and breakfast accommodation for five visitors (individuals, couples or families) who can choose to live and dine together for their stay, or use their room as a base to travel around this scenic area of Suffolk, Aldeburgh being the nearest town to the site.

The new building has a stepping, organic form, clad in shingles, that ‘wriggles’ among the trees in a mature garden (the five acres of the title). Each room is expressed in the roof form and each room has its own timber deck projecting out into the landscape. The new building is directly linked to a retained workshop building. This simple brick building has been repaired and enhanced in the most minimalist way (the addition of an aluminium gutter, roof repairs and the odd new window) so that when you step inside, it is a surprise that it is a single volume of stylish kitchen/ dining room/ lounge.

This imaginative building punches well above its weight

Everywhere the finishes are minimum but the furniture (mid-century classics), pottery, prints, light fittings etc, bring Shoreditch style (and purchasing power) to Suffolk.

What is most surprising and pleasing, given the quality of finishes and workmanship is that this is largely a self-build project where the owners installed the cedar shingles, completed most of the joinery and decorations; working alongside the builder, Paul Rolph, every day on site. The scale and the budget is modest but this imaginative building punches well above its weight.

Judges’ citation  The clients had spent several years looking for a quiet site to build their retirement home, before they found a farm shed located in a wild garden on the edge of a small village in North Yorkshire. Discovering the site with their son Greg, now an associate at Tonkin Lui, and Mike Tonkin, they sought to pull the landscape into the building’s form. A long, double-height gallery maintains the tree-lined approach and a tall library bounded by mirror-backed shelving evokes the copse of silver birch found on the site. Walking into the library through a sliding door from the living room brought gasps from the awards jury. It is the heart of the home and a showpiece for a lifetime’s collection of books.

Walking into the library through a sliding door from the living room brought gasps from the jury

Clever use of light and mirrors gave the impression of an artwork. Otherwise it Is a modest, three-bedroom house, built cost-effectively, but with exquisite detailing inside and out. The house follows a passivhaus strategy of high insulation, high air-tightness, complemented by mechanical ventilation with heat recovery. Timber louvres are neatly integrated into the design of the timber cladding to limit solar gain in the south-facing library. Larch cladding of various widths has been shot-blasted and stained white between galvanised steel fins to offer a rhythmic façade that reads like the bark of the surrounding silver birch trees.

Galvanised steel continues inside with a delicate mezzanine and bridge, using only an 80mm structural depth.

The colour scheme of subtle grey tones, concrete screed floor and white-shaded timber seems to effortlessly complement the art collection in every room. As the architects say: ’The house is a journey of interconnected spaces that alternate between the grand and the intimate […] it is part country cottage, part classical villa.’

Date of completion April 2017
Client Arrant Land
Contract value £465,000
Internal area 130m²
Cost per m² £3,577
Contractor Studio PL

Judges’ citation  A new-build home which is an assertive piece of architecture, justly confident of its place in the street without being disrespectful, and sharing something of the spirit, solidity, and decoration of the Victorian surroundings without veering towards any kind of artificiality. The scheme matches the size, scale and character of the surrounding two-storey dwellings, while providing a 137m² split-level three-storey contemporary home.

The site the architects had to work with was awkward in shape and levels and they had to deal with the challenge of privacy and avoiding overlooking neighbours. Yet they have excelled in dealing with each using the position of the chimney and location. As the end of the terrace the site is an unusal shape, with an imposed kink in the road and angled flank of the adjacent house.

The architects have inventively carved into the space a series of intimately angled living spaces, sprinkled with small glazed courtyards, drawing light and ventilation deep into the low-level kitchen, dining and living spaces. This ‘pushed and pulled’ series of visually connected spaces resolves the complex geometrical challenge, creating a homely space. A timber stair, which greets you at the entrance and stretches the length of the home, is detailed with shadow gaps, and vertical lines of cladding helping light travel down the building. Painted white, this spine of a stair connects the whole house as a single building.

The material selection is tactile, elegant and warm perfectly co-ordinated

The entrance hall has a large window with enough space for coats, bags and shoes. Storage in the living space is carefully hidden away. Bedrooms and bathrooms are a good size, light and decoration kept simple, giving occupants a blank canvas to develop as they wish. The red brick used on the façade matches the highlight brick in the existing terrace and the patterned pre-cast pigmented concrete panel above the front door echoes the decorative brick patterns on the terraced street. The façade is fun and crafted. The material selection is tactile, elegant and warm perfectly co-ordinated with the design as a whole. The client was supportive and encouraging of the architects.

The architects answered the client’s brief and the house is now occupied by clients who love the home.The architects have produced an exquisite crafted home that responds elegantly to its context, providing delight to its users as well as to the surrounding area.

Judges’ citation  This is a wonderful example of where the architect, Steve Kearney, would just not let a project fail. He formed his own construction company, overcoming early setbacks, to deliver the project to a tight budget and time scale. This is a project that is really changing lives, providing inspiring emergency homes for vulnerable women in Southend’s red light district. The layout of the new three blocks around a central space solved the problem of a very restricted site. It creates an appropriately sheltered, private and secure environment for residents who draw support from each other and want to distance themselves from the outside world. The buildings (and the reclaimed garden sheds) are colourful, simply built and carefully placed to maximise the sense of space (there is even a quiet outside space for the staff) on a left-over piece of urban back lot. The building process was complicated too, necessitating bringing materials on to site by hand on occasion. This sort of project makes us all proud to be architects.

This sort of project makes us all proud to be architects

HARP clearly worked hand-in-hand with architect,- Steve Kearney to make every bit of space on a difficult site work hard and make every piece of building material earn its keep. The residents draw great comfort from living together, sharing meals and activities, and exchanging life stories in what feels like an extended family home.
