Location of property: Chiswick
Wilmington Avenue W4 3HA
Local planning borough: Hounslow. This property was also in the Chiswick House conservation area and in a flood risk zone.

Project brief: The client wanted a large open plan space for entertaining, cooking and eating whilst also been able to keep a watchful eye on their two young daughters while they were playing. They also needed an additional bedroom and bathroom.

The result: A new side and rear extension was created replacing an unused area of the patio. The entire house was refurbished including a new WC cloakroom and ground floor level. Bedrooms at first floor level were reconfigured to accommodate more storage and a guest room & en-suite bathroom were created by converting the loft.

The borough’s tough conservation area policies for this road do not allow ground floor extensions to go higher than 2 meters on the boundary. This was complied with by dropping the internal floor levels by 2 steps in order to gain sufficient head room internally. The borough also does not allow the full width side return on this street so a design was created to make this into a feature rather than a problem.
