These three sit together south of the river, close to the water. Most homes here are whole houses, not flat conversions. So the brief is usually the whole house.
Victorian terraces are common in Wandsworth and Putney. Barnes has more detached and semi-detached houses, closer to a village than a suburb.
Putney and Wandsworth fall within the London Borough of Wandsworth. Barnes falls within Richmond upon Thames, so consent can run through two councils. Sources: Wandsworth Local Plan 2023-2038 and Richmond Local Plan 2024-2039. Both read on 7 October 2026.
Roehampton sits between Putney and Barnes, sharing the SW15 postcode. We work there too, on the same terms.
Pricing across the three is open book, on our own rate card. A budget estimate usually lands within a week.
