Thornton House provides 14 high-quality, mixed tenure new homes within an existing estate in Balham, south London, replacing a disused and overgrown ball court.<\/p>\n

The new apartments are arranged as a compact urban villa, located to provide an improved street frontage along Thornton Road. Ranging in height from two to five storeys, the new building acts as a transition between the seven-storey existing estate buildings to the north and two-storey Victorian terraces to the south.<\/p>\n

As part of the redevelopment of the site, a new health and wellbeing garden is provided, including a new under-fives play space, exercise zone and food-growing opportunities. There have also been improvements to lighting and landscaping along the street frontage and site boundary as part of the development. The facilities are shared among new and existing residents.\u00a0<\/span><\/p>\n

The new apartments are arranged around an open central stair core and benefit from a generous recessed balcony or terrace typically connected to the open plan kitchen\/dining\/living space. The scheme was designed as car-free but provides one on-street parking bay on Thornton Road for blue badge holders only; cycle parking is provided for new and existing residents.

Architect\u2019s choices<\/b><\/h3>\n

For the brick specification, mortar choice and precast tonal selection, a range of colours, finishes and products was tested and discussed with the client during the early design stages.<\/p>\n

From that selection, cost, lead times and their suitability within a sensitive context became the defining factors in the final selection of specification.\u00a0<\/span><\/p>\n

In choosing the principal facing brick, it was important to find a tone and quality that would mediate between the new building and the existing post-war estate buildings along Thornton Road and Hydethorpe Road.
\n<\/span>Sean Rafferty, associate director, FBM Architects\u00a0<\/span><\/i><\/span><\/p>\n

\n

\u00a0<\/span>\"\"<\/p>\n<\/div>\n

Specification<\/b><\/span><\/h3>\n

Brick is the principal cladding material, with the composition of window openings and the position of balconies informed by a listed Victorian villa nearby. The brick is laid in Flemish bond to provide scale and variety to the masonry walls.\u00a0<\/span><\/p>\n

The elevations are articulated with a series of recessed spandrel panels above and below window openings, positioned between precast string courses at each storey height. The colour and tone of the precast elements are similar to the brickwork, creating a homogeneous quality to the fa\u00e7ades.\u00a0<\/span><\/p>\n

Secondary elements, such as stone copings, sills and fine metal railings bring a sense of craft and scale to the ensemble.\u00a0<\/span><\/p>\n

Passive environmental solutions have been a key consideration. Sixty per cent of the dwellings are dual-aspect and 40 per cent triple-aspect. Recessed balconies not only increase privacy but act as a shading device for the floor-to-ceiling glazed doors and windows.\u00a0<\/span><\/p>\n

The development was designed to achieve a 72 per cent reduction in carbon dioxide emissions through a combination of air source heat pumps, a highly efficient envelope, PV panels on the roof and thermally efficient double-glazed windows.
