Types of House Extensions We Build in Islington

Rear Extensions in Islington

A rear extension is the most popular way to add space to your Islington home. We build single-storey and double-storey rear extensions that create spacious open-plan kitchen-diners, family rooms, and living areas. Many rear extensions in Islington fall under permitted development, though conservation area restrictions may apply.

Side Return Extensions in Islington

Side return extensions make use of the narrow alleyway beside your property. Extremely popular with Victorian terrace owners across Islington, these extensions transform dark, narrow kitchens into bright, open-plan spaces.

Double-Storey Extensions in Islington

Maximise your additional space with a double-storey extension. Add a new kitchen-diner on the ground floor and an extra bedroom or bathroom above. Our Islington double-storey projects add significant value to your property.

Wrap-Around Extensions in Islington

Combining a rear and side extension, a wrap-around extension creates the maximum amount of additional living space. Ideal for growing families in Islington who need a large open-plan kitchen, dining, and living area.
