The most common type. Extends the back of your home to create a larger kitchen, open-plan living area or additional reception room. Often permitted development for single storey.
Fills in the narrow unused strip down the side of a terraced or semi-detached house, typically to create a wider kitchen or utility room.
Adds space on both floors at once, making it one of the most cost-effective ways to significantly increase your home's footprint.
Combines rear and side return into one seamless addition, maximising the available footprint and creating a dramatic transformation.
Built above an existing garage, outbuilding or single-storey section. A clever way to add a bedroom or bathroom without using any garden space.
