An addition and remodelling to a Victorian house in Twickenham. An imprint of the existing front facade is relocated within a floating stainless steel frame to the front of a new side addition. This floating facade is separated from both the new addition behind and existing house by a band of structural glass. The new addition is characterised by its separation and glass connection to the existing building at both the front and the rear.
The front facade is a subtle framing of the existing building with a cantilevered structure. To the rear the cantilever condition is repeated and more explicit in its execution. A new rear facade folds over the glazed void framing views into the garden. The facade hovers at first floor level unsupported by columns. It cantilevers from the original house over the garden to create a protected steel stair which links to both the garden and the new kitchen and dining space. The basement level is lowered to the rear to form a new dining and kitchen space. A double height glass void links the new side addition, new basement, a new study and the existing ground floor living space. Each folds into the glass volume and has framed views either into or through it to the garden beyond.
There are 12 cantilevers within the project. Some are discreet and some are overt; the primary ones being to the front and rear elevation of the new side addition. The floating framed front elevation sits on a steel cantilever frame at first floor level and is restrained laterally by two 12mm rods at roof level. The cutting and repositioning from the existing building attempts to be subtle but unnerving; on closer inspection, what appears to be a traditional elevation is dislocated fragment held in a stainless picture frame which in turn floats within a glass enclosure. In contrast the rear elevation hangs form a hidden cantilevering steel beam of 600mm depth at roof level, but its dramatic relationship with the landscape is confident and pronounced.
The new front elevation borrows the existing brick, stone mouldings and box sash windows of the main front façade and sets them in the framing of contemporary materials of steel and glass. To the rear the project has new palette of structural glass, eccentric framed glass and rendered exterior walls.
