Surrey

Surrey projects are a different animal from Central London. Bigger plots, detached houses, room for serious new builds. We work across the county - from extensions in Esher to ground-up houses in Cobham - handling the architecture, planning and construction ourselves.

What We Do in Surrey

New builds, extensions and renovations across the county

Surrey has something that most of London simply does not - space. The plots are larger, the houses are detached, and there is room to do things properly. That changes the kind of projects we take on here. New build houses on private plots. Large extensions that wrap around three sides of a property. Full renovations of period homes that need bringing back to life.

The planning landscape is more varied than London too. Surrey has multiple district and borough councils - Elmbridge, Guildford, Mole Valley, Reigate and Banstead, Waverley - each with their own local plan. Parts of the county sit in the Green Belt, which adds another layer entirely. We navigate all of it, whichever part of Surrey your property is in.

The design quality stays the same whether we are working in Chelsea or Cobham. The only difference is scale - and in Surrey, the scale tends to be bigger.

  • New build homes
  • Large rear and side extensions
  • Loft conversions
  • Basement conversions
  • Full house renovations
  • HMO conversions for developers

Our Approach

London studio, Surrey projects

We are London-based, but Surrey is core territory. A significant proportion of our project work happens outside the capital - in Cobham, Esher, Weybridge, Guildford, Leatherhead and the towns between. The commute is short, the site visits are regular, and the working relationship is the same as any local project.

We have completed projects across the county and understand how the different planning authorities operate. Elmbridge is not Guildford. Mole Valley is not Reigate and Banstead. Each has its own priorities, its own sensitivities, and its own way of handling applications. That local knowledge matters when you are trying to get something built.

What makes us different is that architecture and construction sit under one roof. We design the project, take it through planning, and build it with our own team. There is no handover to a separate contractor, no gap between what gets drawn and what gets built. One contract, one point of contact, from the first sketch to the finished house.

If you have a plot, a property, or just an idea - we are happy to talk it through. Most projects start with a conversation about what is possible.

Common Questions

Architecture in Surrey - answered

Do I need planning permission for an extension in Surrey? +
It depends on where you are in the county. Surrey has multiple planning authorities - Elmbridge, Guildford Borough, Mole Valley, Reigate and Banstead, among others - and each has its own local plan. Smaller rear extensions often fall under permitted development, but large parts of Surrey sit within the Green Belt, which imposes strict limits on what you can build. Conservation areas in towns like Cobham and Esher add further restrictions. We check the planning position for every property before starting any design work.
How much does a new build cost in Surrey? +
Construction costs for a new build in Surrey typically range from £2,500 to £4,000 per square metre, depending on specification and complexity. The plot cost is separate and varies enormously by location. For a bespoke detached home, construction alone can start from around £500,000 and go well beyond that depending on size, finishes and site conditions. We provide detailed cost estimates early so you can plan with confidence.
Does Rosace work outside London? +
Yes. Surrey is core territory for us - we regularly work in Cobham, Esher, Weybridge, Guildford, Leatherhead, Reigate and beyond. We also take on projects in Hertfordshire, Kent, Essex and Buckinghamshire, generally within a 30-mile radius of London. Our studio is London-based, but a significant portion of our work is outside the capital.
What types of projects do you do in Surrey? +
We work on new builds on private plots, large extensions on detached homes, loft conversions, renovations of period properties, and HMO conversions for developers. Surrey projects tend to be larger in scale than our inner London work because the properties and plots allow for it. We handle architecture, planning and construction in-house.
