House Extensions Fulham

The main cost factors are the type of extension, the amount of structural work, the condition of the existing property and the level of finish required. In Fulham, access, shared walls, neighbouring properties, drainage changes and older services can all affect the build. Glazing, joinery, kitchen specification and internal finishes also play an important role in the final cost.

For most Fulham house extensions, £30,000 or £40,000 is unlikely to be enough. Even a modest extension can involve foundations, steelwork, roof construction, glazing, building-control requirements and internal finishing. Victorian terraces may add further complexity through access, drainage, existing services and structural integration. A realistic budget depends on the confirmed drawings, specification and scope of work.

It depends on the property, location and proposed works. Some house extensions may fall within permitted development, while others require planning permission, especially where previous alterations, conservation constraints or property-specific restrictions apply. CFB does not act as a planning consultant, but we can work with your appointed architect or consultant and build from the agreed drawings once the correct route has been confirmed.

In many cases, yes, but the right approach depends on the property type, existing structure, garden depth, access and neighbouring buildings. Victorian terraces and family houses in Fulham are often well suited to rear extensions, side return extensions or kitchen-led ground-floor extensions. A site-specific review is needed to understand what is practical for the property.

Rear extensions and side return extensions are often well suited to Fulham terraced houses. A rear extension can improve the connection to the garden, while a side return can widen a narrow kitchen or dining area. Where space and planning constraints allow, a wraparound extension may combine both approaches. The right option depends on the existing layout, structure and drawings prepared by your appointed professional team.

A side return extension can be suitable for Fulham homes with unused space alongside the rear room or kitchen. It can widen the ground floor, improve circulation and help create a more practical kitchen, dining and family living space. These projects usually require structural openings, steelwork, drainage coordination and careful detailing where the new extension meets the existing house.

Yes, many Fulham house extensions are built around open-plan kitchen and living spaces. This usually involves extending to the rear or side, forming structural openings, installing steelwork and coordinating glazing, rooflights, services and finishes. The focus remains on extension construction rather than standalone kitchen renovation.

Timelines vary according to size, complexity, access, structure and specification. A straightforward extension may take several months once drawings, permissions and procurement are in place, while larger or more complex terrace-house projects can take longer. Programme can also be affected by structural works, specialist glazing, bespoke finishes and coordination with the appointed professional team.

A house extension will always create some disruption, particularly in Fulham streets with close neighbours and limited access. Careful planning helps reduce the impact. We consider access, deliveries, protection, site cleanliness, neighbouring properties and sequencing before works begin. Where possible, we phase the works in a practical way while keeping the build controlled and communication clear.

A well-planned and well-built extension can add value to a Fulham property, especially when it improves light, layout, kitchen space and connection to the garden. The strongest results usually come from extensions that feel properly integrated with the original house and are finished to a high standard. Value uplift depends on the property, market conditions, design quality and build specification.

Yes. We regularly work with appointed architects, interior designers, structural engineers and consultants on house extensions in Fulham and West London. Our role is to deliver the construction work on site, coordinate trades, follow the agreed drawings and specifications, and maintain clear communication throughout the build.
