Wrap-around extensions in London
The combined rear and side extension: a single L-shaped volume that reorganises the ground floor of the house.
The combined rear and side extension: a single L-shaped volume that reorganises the ground floor of the house.

A wrap-around extension combines the rear and side extensions into one continuous L-shaped volume, reorganising the ground floor of the house as a whole.
Because it alters the plan more fundamentally than either extension alone, the design begins with the whole ground floor: circulation, light, views to the garden and the structural strategy that allows walls to be removed. The roof form is resolved early, as it governs both daylight and planning acceptability.
Wrap-around extensions usually require a householder planning application. The studio establishes the planning position, the likely views of the local authority and the party wall obligations before design is developed.
The project moves through feasibility, concept design, planning, technical design and construction, with structural design coordinated with the architecture throughout.
