Building on local homes

Putney has many Victorian and Edwardian terraces and semis that suit rear and side return extensions, plus rear dormers. Richmond has a wider mix, from Georgian and Victorian houses to riverside properties. Richmond upon Thames has 85 designated conservation areas, so design and materials need care, and homes close to the Thames may also need flood risk considered at the planning stage.

Questions homeowners ask

Do conservation areas stop me extending in Richmond?

Not necessarily, but they add rules about design, materials and what can be done under permitted development. We check this for your address first.

We build rear dormer, hip-to-gable and L-shaped lofts, and advise on the best option after a site visit.
