Building in Cobham.
Cobham is a green-belt village with an A3 commuter pull — a mix of country lanes, gated estates around Fairmile and the older centre near the High Street. Plot generosity makes ambitious designs achievable, but green belt rules need careful navigation.

What we deliver in Cobham.
Each Cobham street has its own typical layout — Victorian terrace, Edwardian semi, 1930s detached. We adapt the recommendation to the house, the planning context and how you actually want to live.
Wrap-around and rear extensions add open-plan kitchens and family rooms on detached homes. We work with the green belt 30/50% guidelines from day one of design.
Loft conversions are common on the older village stock; on larger detached homes we sometimes add full attic suites with two bedrooms and a bathroom.
Replacement dwellings in green belt are possible within volumetric limits — we have delivered several modern family homes that stay within the rules and add real value.
SERVICE 01 House extensions in Cobham
A house extension is the biggest investment you can make in your home — it should transform how your family lives, not just add square metres. We design every extension around how you actually use your space, with a fixed, itemised price and stage-based payments so you stay in control from first sketch to handover.

SERVICE 02 Loft conversions in Cobham
A loft conversion adds an entire floor without losing any garden. We design lofts as proper rooms — full-height ceilings, generous windows, en-suite bathrooms — not afterthoughts squeezed into the rafters.
