Barnes is London's best-kept village secret — a place of Georgian cottages, Victorian terraces, and Edwardian villas gathered around a green and a duck pond, with the Thames curving quietly alongside. Our architects understand every conservation area, every Richmond Council requirement, and every detail that makes SW13 one of the most rewarding places to renovate in London.
Barnes has the rare quality of feeling like a proper English village while sitting barely five miles from central London. The duck pond on Barnes Green, the weatherboarded cottages along Church Road, the common stretching from the High Street to the Wetland Centre — it is a place that has resisted the pressures of metropolitan development more successfully than almost anywhere else in the capital.
The housing stock reflects centuries of organic growth. Georgian cottages cluster around the Green and along the riverside, many dating from the eighteenth century when Barnes was a fashionable retreat from the city. Victorian terraces line the streets between the railway and the common, their proportions generous, their detailing well preserved. Edwardian villas — particularly along Castelnau and the avenues leading towards Hammersmith Bridge — added a more expansive domestic architecture at the turn of the twentieth century. And along The Terrace, a remarkable row of riverside houses offers some of the finest Thames-side living in London, with views across to Chiswick and the Wetland Centre beyond.
For homeowners in SW13, this architectural heritage creates both a privilege and a responsibility. Three conservation areas — Barnes Green, Barnes Common, and Castelnau — cover much of the village, and Richmond Council takes its conservation duties seriously. Period property refurbishments must respect original proportions and materials. Rear extensions need sensitive design that complements the existing building. Even loft conversions require careful thought about rooflines and streetscape impact. Every renovation in Barnes demands an understanding of what Richmond will permit, and the skill to make the result feel as though it has always been there.

Barnes falls under the London Borough of Richmond upon Thames — a council that takes conservation seriously but is generally reasonable with well-designed proposals. Three conservation areas cover much of the village: Barnes Green (protecting the historic village core around the pond and Church Road), Barnes Common (covering the streets around the common and railway), and Castelnau (the grand avenue of Victorian and Edwardian houses leading towards Hammersmith Bridge).
Richmond Council expects new work to respect the existing character of the area. Rear extensions are generally supported where they are subordinate to the original building, use sympathetic materials, and do not harm neighbours' amenity. Loft conversions can be achieved under permitted development in some cases, though conservation area restrictions may require a planning application. For riverside properties, flood risk assessments are typically needed, and the Environment Agency may need to be consulted. Our architects understand Richmond's expectations and design to achieve approval first time.

Yes. Rear extensions are one of the most popular projects in Barnes, particularly for Victorian terraces and Edwardian villas. In conservation areas, planning permission is typically required, and the design must be subordinate to the original property and use sympathetic materials. Our architects design to achieve Richmond Council approval first time.
A full refurbishment in Barnes typically costs £500–£900 per square metre, depending on the scope and specification. Rear extensions range from £2,800–£4,500 per square metre. Conservation area requirements and Barnes's high specification expectations are reflected in the pricing. All our projects are delivered on fixed-price contracts.
In many cases, yes. Victorian terraces and Edwardian villas in Barnes often have loft conversion potential. Outside conservation areas, some loft conversions can proceed under permitted development. Within conservation areas, a planning application is likely required. Our architects assess each property individually and design roofline solutions that Richmond Council will support.
Properties along The Terrace and near the Thames may fall within Flood Zone 2 or 3. A flood risk assessment is typically required for planning applications, and the Environment Agency may need to be consulted. Basement conversions for riverside properties require specialist waterproofing. Our engineers have experience with Thames-side structural and flood mitigation works.
