The Offington Estate in Sutton was designed in the 1970’s with a Californian style house design and generous back gardens. The design was ahead of its time with features such as floor to ceiling windows. The existing house is set at an angle on the rectangular site which causes the main living spaces to have oblique views of the garden. The existing house was fully refurbished and the dormers retained not to take away from the character of the house.

The new extension looked to realign part of the house to address the rear garden. The new modern extension features full-length glazing to bring the garden into the house. The design concept was to use tall vertical brick walls, which follow the boundary walls to maximise the views of the garden. Brick was used in the new extension to distinguish the existing style from the new addition. A large terrace was then added which connects the old to the new and creates a south-facing two-sided courtyard that acts as an outdoor living area.
