Modern two-storey extension and reorganisation of a 1920s house, adding a kitchen and living space on the ground floor, and master bedroom, bathroom and terrace on the first

A rear and side addition is clad with over 120 glass reinforced concrete panels that were used in a vertical pattern becoming lighter towards the sky, and arranged to fit with bespoke European oak windows and full-height sliding doors.

Internally, the kitchen and extended living room form a spacious ‘S’ shaped living space, with large triple sliding doors opening to a decked area with a concrete BBQ alongside.

On the first floor, a frameless glass box sitting on a green roof links the existing building with the master bedroom suit in the addition.

Environmental improvements include a highly insulated envelope, solar water heating, photovoltaic panels and a heat recovery system, which extracts hot air from the glass box that acts as a solar collector.

At the bottom of the garden is a shed faced with polished stainless steel to reflect the greenery that is built from roof joists, partition studs and old roof boards, which would otherwise have been thrown away.
