We design, plan and build house extensions across Hammersmith and the wider Hammersmith and Fulham borough — one team, one fixed price, one project manager from sketch to handover.
Hammersmith mixes Victorian and Edwardian terraces with riverside streets and period flats. It's strong territory for extensions and loft conversions that give growing families more room without leaving a well-connected area.
Rear and side-return extensions open up the typical Hammersmith terrace into bright, open-plan living space. We manage design, planning and build as one team.
Planning drawings, building-regulations and party-wall paperwork are prepared and submitted by our own team — including for conservation-area or listed properties where extra consent is needed. One point of contact owns both the approvals and the build, so nothing falls between an architect and a separate contractor.
No subcontractor juggling. From the first sketch through structural engineering to final snagging, your project moves through people who all sit in the same office and answer to the same project manager.
You pay in stages, only after each stage is signed off. Variations only happen when scope genuinely changes — and they go through written authorisation, never a verbal "while we are at it".

It depends on the property. Many house extensions fall under permitted development, especially in Hammersmith and Fulham. Where planning is needed (conservation areas, listed properties, larger schemes), we handle the application end-to-end.
Many extensions fall under permitted development. We assess your property and tell you exactly what you need on the first visit.
A single-storey extension takes 12–16 weeks from breaking ground to completion. Double-storey runs 16–22 weeks.
