What we deliver in Richmond
Every street sits differently — a period terrace, a post-war semi, a modern infill. We shape the recommendation around your actual house, its planning context and how you want to live.
We extend and refurbish Georgian terraces near the green with carefully matched brickwork and glazed rear extensions. In newer areas we design contemporary additions.
Dormer and mansard conversions add bedrooms; on Georgian houses we often use inset dormers with lead cheeks to maintain the appearance.
Infill plots in modern developments allow new family homes. Designs respect street scale and materials.

Common Richmond questions
Things you might need to know about building in Richmond.
Do I need planning permission for an extension in Richmond?
Many extensions in Richmond fall under permitted development. Where a full application is needed, it goes to Richmond upon Thames Council — we assess your property type, the council's restrictions and any conservation status on the first visit, and handle the application ourselves.
How long does a project in Richmond typically take?
From first consultation to handover: 6–9 months for a single-storey extension or loft, 9–14 months for double-storey or wrap-around. We give you a tighter estimate after the survey.
Are there conservation areas in Richmond?
Several streets in Richmond upon Thames Council's area fall within conservation areas that restrict materials and detailing. We check your exact address against the register on the first visit, and we have approved schemes in conservation areas nearby.
What is a typical extension cost in Richmond?
Build cost in this part of London runs £2,500–£4,000 per square metre for a finished extension including kitchen and finishes. Our calculator gives a personalised estimate.
