NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle loft conversions, dormers and mansards in Weybridge KT13, under one contract. A main dormer loft typically runs £90k to £140k. A mansard loft runs £140k to £220k. Call 020 7731 6841, and a budget estimate typically follows within seven days.

Weybridge is large detached houses, many on private roads. Roofs are big, and often hipped.

Outside a conservation area, national rules let a detached house add 50 cubic metres.

Inside one, that right falls away. Weybridge has three: Town Centre, Monument Green and Templemere.

A private hill estate stands apart. Its residents’ association must consent in writing first.

We have not yet finished a project in Surrey. Our Town and Country division runs work here.

How much can a detached Weybridge house add in the roof without planning?

Up to 50 cubic metres, outside a conservation area.

We confirm with a lawful development certificate before building.

Is a Monument Green house in Weybridge free to convert its loft?

No. Monument Green is a conservation area, so roof rights do not apply.

A planning application is needed.

Does the private hill estate in Weybridge control loft works?

Yes. Its residents’ association must consent in writing first.

We read its current guidelines for each site.

Can a hipped Weybridge roof become a full loft floor?

Often, by turning a hip into a gable or adding a rear dormer.

Both count towards the 50 cubic metre limit.
