House Extensions Fulham

House extensions are Fulham's favourite home improvement, and with good reason. The area's Victorian and Edwardian terraced houses — while charming and well-proportioned — often lack the spacious, open-plan living areas that modern families need. A well-designed extension can transform a Fulham terrace, adding a generous kitchen-diner that flows into the garden, creating an additional bedroom or home office, or providing the utility and storage space that busy households demand.

GS Renovation has been building house extensions across Fulham for over three decades. We specialise in the types of extensions that work best for Fulham's housing stock: side return extensions that widen narrow kitchens, single-storey rear extensions that create open-plan kitchen-dining spaces, and loft conversions that add a valuable top-floor bedroom and bathroom. Many of these projects can be completed under permitted development rights, avoiding the need for a planning application and significantly reducing the project timeline.

Our Fulham extension service covers everything from initial design and planning through to construction, fit-out, and final decoration. We work with experienced architects and structural engineers, manage all building control and party wall processes, and coordinate every trade to deliver a seamless, stress-free project from start to finish.

Rear Extensions

Rear extensions in Fulham typically extend the kitchen into the garden, creating a generous family space with bi-fold or sliding doors that open directly onto the rear garden. We build single-storey flat-roof extensions with roof lanterns for overhead light, as well as more traditional pitched-roof additions. Every rear extension is designed to complement the existing house and maximise the connection to outdoor space.

• Bi-fold and sliding door installation
• Flat roofs with roof lanterns
• Open-plan kitchen-dining-living creation
• Underfloor heating and premium flooring

Side Return Extensions

The side return extension is Fulham's signature home improvement. By building into the narrow passage that runs along one side of a terraced house, you can add up to 40% more width to your ground-floor rooms. Combined with the removal of the wall between the old kitchen and dining room, this creates a single generous space that transforms the way your family uses the home. Most Fulham side return extensions fall within permitted development rights.

• Side return infill construction
• Permitted development compliance
• Combined side and rear extensions
• Structural steelwork for wall removal
• Skylights and glazed roofing
