We design, plan and build house extensions across Putney and the wider Wandsworth borough — one team, one fixed price, one project manager from sketch to handover.
Conservation areas, Article 4 directions, party-wall hotspots — every Wandsworth street has its own permission map. We have submitted dozens of approved schemes across Putney and the surrounding postcodes.
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".

Yes — Putney (SW15) is well within our Wandsworth working area. We typically deliver several house extensions projects across this borough each year.
End-to-end (consultation → handover) usually 12–22 weeks. Build phase alone is shorter — most house extensions sites complete in 8–18 weeks depending on scope and finishes.
Typical range: From £2,500 / m². Our online calculator gives you a tighter figure based on your house type and ambitions; the fixed quote follows a free site visit.
It depends on the property. Many house extensions fall under permitted development, especially in Wandsworth. 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.
For most rear extensions, yes. We dust-seal the working area and maintain access to your kitchen and bathroom.
