Optimising Permitted Development

Two part rear extension to an Edwardian terrace close to the Wimbledon tennis grounds.

Why is this special?

Split level roof allows sideways clerestory light and hides the inevitable beams without feeling op-pressive. Cantilever porch to control summer sun.

The Challenge

Both neighbours already had extensions differing in depth and height. Our clients wanted to a quick start without waiting for planning consent.

Our Solution

Andrew designed the project within the heights and dimensions allowed as ‘Permitted Develop-ment’ which allowed a rapid start. But at the same time made use of the sun path and neighbours’ different levels of roof to design an extension on seemingly in two parts to feel bigger than the small additional area might suggest. Angled doors to face deep into the beautiful garden are em-phasised by the squared off roof over resulting in a cantilever porch.

The Results

Two level roof partly set at an angle to align with neighbour’s differing extensions gains an extra south facing high level window and makes an intimate but efficient kitchen dining room, freeing up the original kitchen as a study.
