Architecture OFIS_VILLA T-EXTENSION_2012_22

The client family who lives on the ground floor of an apartment villa, commissioned the redevelopment on the south side of the existing building. The client has a functional disability and is restricted to a wheelchair. He lives with his wife, three children, and a dog.


OFIS_VILLA T-EXTENSION_2012_8The existing “Villa Dular” is a typical modernistic villa originally designed in 1932 by architect Costaperaria; a white cube with an extensive roof terrace and a top volume finished in wooden cladding. It is surrounded by a garden and other similar residences of its time. The villa is currently inhabited by different owners on each floor.


OFIS_VILLA T-EXTENSION_2012_12The task at hand was to design a new extension to the ground floor with a dining area and living space, including a covered parking for a car and a storage space for bicycles. The client requested the roof be used as a terrace for the apartment on the first floor. All floor surfaces were designed with slopes and wheelchair access in mind.


OFIS_VILLA T-EXTENSION_2012_16The T shape extension works as an umbrella above the living space: supporting the terrace on one side and creating a parking roof on the other side. The roof over the parking and ramp is a cantilevered pergola covered with Perspex panels in a light green color. The connection between the existing villa and the intervention is a glass volume as part of the living space. The sides that face the garden and the entry courtyard are large panoramic glass walls with a framed sliding window in oiled oak.


OFIS_VILLA T-EXTENSION_2012_20The cladding of the new extension is an assembly of bleached larch wood verticals in 2×2, 3×3 or 4×4 cm, in a rhythm that creates a pleated texture.
