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

It depends on the property. Many house extensions fall under permitted development, especially in Surrey. 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.
