Types of House Extensions
Rear Extension
A popular option for ground-floor expansions — ideal for adding light-filled living or dining space and improving the connection to your garden.
Popular in: Fulham (SW6), Chiswick (W4), Acton (W3), Hammersmith (W6)
Side-Return Extension
Perfect for Victorian terraces and narrow plots, a side-return extension makes use of otherwise wasted alley space to widen kitchens or create an open-plan layout.
Popular in: West Kensington (W14), Notting Hill (W11), Putney (SW15), Chiswick (W4)
Wraparound Extension
Combining a rear and side-return extension, this solution maximises ground-floor space and works well for open-plan kitchens, bifold doors and family living zones.
Popular in: West Kensington (W14), Notting Hill (W11), Putney (SW15), Chiswick (W4)
Double-Storey Extension
Double your space by extending both the ground and first floors — ideal for adding bedrooms, bathrooms or upstairs studies while future-proofing your home.
Popular in: Chiswick (W4), Ealing (W5, W13), Acton (W3), Hammersmith (W6)
Basement + Extension Hybrid
For homes with tight footprints, a basement conversion paired with a ground-floor extension delivers significant space without impacting the street view.
Popular in: Chelsea (SW3), Kensington (SW7/W8), Notting Hill (W11)
Loft-to-Extension Integrations
We often link loft conversions to new extensions through reconfigured staircases or double-height voids, creating dramatic, light-filled volumes and vaulted ceilings.
Popular in: Fulham (SW6), Shepherd’s Bush (W12), Ealing (W5)

House Extension in Fulham
This Fulham project centred on extending a late-Victorian terrace to create a brighter, more functional family home. Our scope included a full back-to-brick programme and the construction of a rear extension, designed with Crittall-style glazing to introduce natural light and improve flow. The build balanced structural precision with respect for period detailing.
Delivering house extensions London requires careful coordination, particularly on narrow residential streets.

House Extensions FAQs
Most house extensions in London take between two and four months to complete, depending on the size, complexity, and type of build—whether a rear, side return, wraparound, or double-storey extension.
Where We Work
We build house extensions across Chelsea, Fulham, Kensington, Notting Hill and surrounding West London postcodes — including SW3, SW5, SW6, W6, W10 and W11. Our team understands the planning sensitivities, architectural nuances, and logistical challenges involved in extending homes in these areas.
If your extension project sits just outside these postcodes but aligns with our approach, we’re happy to advise. We occasionally take on bespoke or architect-led extensions further afield where our craftsmanship, communication, and structural expertise can add real value to the project.
