Building in Kew.
Kew is famous for its botanical gardens and leafy streets. Its riverside location and UNESCO-listed heritage make it a sensitive planning environment — planning authorities require alterations to preserve the historic character.

What we deliver in Kew.
Each Kew street has its own typical layout — Victorian terrace, Edwardian semi, 1930s detached. We adapt the recommendation to the house, the planning context and how you actually want to live.
Rear extensions with large rooflights bring natural light into narrow Victorian houses. Wrap-around extensions need careful roof detailing to satisfy planning.
Mansard conversions or modest dormers create extra space while respecting rooflines.
Infill plots between the river and gardens allow bespoke family houses; every design must blend with the surrounding period architecture.
SERVICE 01 House extensions in Kew
A house extension is the biggest investment you can make in your home — it should transform how your family lives, not just add square metres. We design every extension around how you actually use your space, with a fixed, itemised price and stage-based payments so you stay in control from first sketch to handover.

SERVICE 02 Loft conversions in Kew
A loft conversion adds an entire floor without losing any garden. We design lofts as proper rooms — full-height ceilings, generous windows, en-suite bathrooms — not afterthoughts squeezed into the rafters.

Common Kew questions.
Things you might need to know about building in Kew.
Do I need planning permission for an extension in Kew?
Many extensions in Kew fall under permitted development. We assess your property type, council restrictions and any conservation status on the first visit.

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.

Possibly — many Richmond upon Thames streets are within conservation areas which restrict materials and detailing. We have approved schemes in conservation areas across the borough.
What is a typical extension cost in Kew?
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.
