Shared walls, across West London.

1996 Act
The law behind every notice
14 days
For a neighbour to reply
12 months
Before an unused notice lapses

NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle party wall notices and awards in West London W/SW, under one contract. Fees are priced per project by our own quantity surveyor, from the actual scope. Call 020 7731 6841, and a budget estimate typically follows within seven days.

A West London terrace shares a wall on each side. Steels, underpinning and nearby digs all bring in the Party Wall Act.

We serve notices once the structural design is fixed. Neighbours see the same drawings that the work will follow.

If a neighbour does not reply within 14 days, a dispute arises. Surveyors are then appointed and an award is agreed.

Our Kensington digs went three floors down beside their neighbours. In Chelsea, we underpinned the party walls for a full footprint basement.

Open the calculatorThe 2026 cost guide

When do I need a party wall surveyor in West London?

When you cut into, raise or underpin a shared wall.

And when you dig near a neighbour’s foundations.

How much notice must I give my neighbours?

Two months for work to a party wall.

One month for a new wall on the boundary, or a nearby dig.

What happens if my neighbour does not reply?

After 14 days, silence counts as a dispute.

Surveyors are appointed, and they agree an award.

Who pays the neighbour’s surveyor?

The building owner usually does, for reasonable fees.

We set it out in the price before notices go.

Does the council get involved in party walls?

Not directly. The Act sits outside planning.

Kensington and Chelsea advises starting party wall talks before applying for a basement.
