NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle house and kitchen extensions in Weybridge KT13, under one contract. A rear kitchen extension typically runs £160k to £250k. A side return extension typically runs £140k to £220k. Call 020 7731 6841, and a budget estimate typically follows within seven days.

Weybridge houses stand detached, many along private roads. Plots are wide, so an extension rarely fights for space.

Common briefs: a rear kitchen, a family room, or a boot room.

National rules cover a lot of it. One storey can push 4 metres back, or 8 through prior approval.

Beyond those limits, Elmbridge decides through a full application. Conservation areas add heritage tests.

One hill estate also wants its residents’ association to agree in writing. We send them drawings early.

Can a Weybridge kitchen extension go 8 metres into the garden?

On a detached house, prior approval can allow that depth.

It is not open in a conservation area.

Glazing and rooflights keep a deep room bright.

Will Weybridge Green Belt rules limit a side extension?

Where the plot is Green Belt, added volume and footprint are capped.

About 57% of Elmbridge carries that designation.

We confirm your plot’s status at the first visit.

Does the hill estate in Weybridge review extension drawings?

Its residents’ association gives written consent before work begins.

We share drawings with them early, alongside planning.

What does a wraparound extension in Weybridge cost?

Our 2026 cost guide puts a wraparound at £200k to £320k.

That is a London figure, as no Surrey project is finished yet.
