The site has a unique configuration:
the average width is 3.50 m and its length is about 11.50 m. We
designed this extension to melt into its surroundings with
little disruption to the existing built environment. We wanted it to
become a passageway to the garden.
The configuration of the plot and its
difficult accessibility required us to
use non-traditional construction methods and materials.
The extension consists of two elements:
a masonry base and a wooden module which join perfectly with the
outer boundaries of the adjacent building. The lightness of the
wooden frame structure reduces the need for foundations along
the neighbors' boundary walls as well as reducing the
construction time on site. The existing building provides support to
the new construction. The glass roof - an ethereal element - connects
the existing building to the extension.
Reduced to their simplest expression,
the ground floor walls are used solely to anchor the upstairs
structure. They visually disappear to let the exterior metal poles
stand out, therefore allowing the surrounding landscape into the
house. The interior/exterior relationship is blurred and
the large openings frame the garden. A covered terrace servers as a
buffer between these two spaces.
A perfect transparency is maintained
between the east and west facades, both on the ground and upstairs
floor, so that upon entering one immediately perceives the
garden. Conversely, from the terrace, the urban context can be
imagined.
The use of varying materials on the
facades provides legibility and visual hierarchy. On either side, the
facades are clad in easy-to-maintain larch. In contrast, the
gables - abstract elements of the project - are clad in state-colored
steel siding to harmonize with the local vegetation.
