We design, plan and build loft conversions across Thames Ditton 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 Thames Ditton 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 — Thames Ditton (KT7) is well within our Surrey working area. We typically deliver several loft conversions projects across this borough each year.
End-to-end (consultation → handover) usually 8–14 weeks. Build phase alone is shorter — most loft conversions sites complete in 8–18 weeks depending on scope and finishes.
Typical range: £60k–£140k typical. 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 loft conversions 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 lofts fall under permitted development if you stay within volume limits. Conservation areas always need full planning. We handle either route.
You need at least 2.2m of head height in the existing loft. We measure on the first visit and confirm what conversion fits.
Most of the work happens upstairs, with rooflight access for materials. You stay in your home throughout.
