A radical extension and reconfiguration of a 1920s house with excellent environmental credentials.
The scheme re-orientates the living spaces towards the lovely rear garden with a bold extension, clad with concrete panels. The panels are manufactured from glass-reinforced concrete, a lightweight material which can be manufactured to precise colours and sizes. Over 120 panels form a vertical pattern becoming lighter towards the sky, and are set against European oak windows.
To the rear the panels form a striking new element in the garden, whilst from the street just a glimpse can be seen to the side of the existing house, a strategy that was important given the house is within a conservation area.
Internally, a new kitchen and extended living room form a spacious ‘S’ shape, with large triple sliding doors opening to a decked area with a concrete BBQ alongside. The floor of the kitchen is a bespoke tessellated pattern of yellow, white and grey tiles, hiding an electric hatch to a wine cellar below. In the living room the original 1920s pine parquet floor was retained and repaired.
Upstairs, a frameless glass box floods the circulation corridor with light and links to a new master bedroom, dressing room and bathroom with its own timber-clad secret terrace.
The project significantly increases the energy efficiency of the house. The glass box acts as a solar collector, with hot air distributed throughout the house by a heat recovery system. Solar water heating and photovoltaic panels were installed and a recycled water tank was placed in the old cellar and provides water for the garden. Insulation was specified to be more than 20% above regulations.
