Copthorne Road, WD3

Housing Extension, Croxley Green, Hertfordshire

For this house extension, an existing ‘Arts and Crafts’ style house required extending for family use. Mark Fairhurst Architects were asked to develop a sustainable design to provide accommodation for living, sleeping and parking utilising materials in keeping with the existing building.

An annex to the house has been created connected via a timber clad link and separate garage accommodation providing a new paved courtyard to the rear. The existing single storey utility room was replaced with a new kitchen and breakfast room converting the existing kitchen into a dining area. A covered parking bay is provided with direct access to the kitchen and utility room with new living room all housed in a single storey pavilion structure. A new master bedroom with ensuite bathroom and changing room is located at first floor.

The subordination of the annex to the existing building is established by using low pitched lead clad roofs maintaining the dominance of the existing tiled pitched roofs. The new contemporary form creates an individual identity for the annex while respecting the quality and materials of existing building chosen to complement the brick and lead detailing.

Solar panels fixed to the south facing lead roof provide renewable energy for the hot water cylinder, a green roof has been installed to the double garage and underground rainwater recycling tanks collect rainwater from the new roofs.
