What we deliver in Ham
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.
Rear and side extensions add family space to Ham's houses while respecting the green character of the area. We handle any consent the setting requires.
Loft conversions add bedrooms without extending the footprint — a good fit where preserving the garden and the streetscape matters.
On suitable plots we deliver replacement dwellings and new-builds designed to sit comfortably in Ham's open, green context.

Common Ham questions
Things you might need to know about building in Ham.
Do I need planning permission for an extension in Ham?
Many extensions in Ham 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 Ham 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 Ham?
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 Ham?
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.
