A rear extension builds onto the back garden across the width of the property. It widens your home footprint by giving you more floor space to extend your kitchen or to add more living areas. As one of the most common single-storey extension types, it proves to be the best way to unify the rear end of Victorian and Edwardian properties.
These properties have a less-integrated area at the back – a character found in period properties. Rear extensions London is the modern solution to creating a more open and free-flowing space. It is the perfect method to transition to an open-plan floor area that accommodates the kitchen, a dining area, and a sitting area. Rear extensions can be either single-storey or double-storey.
