NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle party wall notices and awards in Chelsea SW3, 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.
Chelsea terraces often rise four storeys, sometimes five. Most share a wall on each side.
Removing a chimney breast cuts into that wall. So does pocketing a new steel.
Both are party structure work, needing two months’ notice.
Basements are the other common trigger. Policy CD11 allows one storey, under half the garden.
Even one storey digs close to the neighbours’ foundations, so notice is needed.
We record each adjoining house first, then agree the award.

Further reading, from the journal
Does removing a chimney breast in Chelsea need a party wall notice?
Usually. Cutting a projection off a party wall is notifiable work.
It takes a party structure notice, two months before work starts.
Does a Chelsea mansard need a party wall award?
Often. Raising the party walls for an extra storey is notifiable.
Steels bearing on the shared walls usually are too.
Planning is a separate question for the borough.
How early should Chelsea neighbours hear about a basement?
Before the planning application, the borough advises.
Formal notices follow once the design is settled.
Each notice lasts a year if work has not begun.
Can a Chelsea neighbour refuse party wall consent?
They can dissent, but they cannot block work the Act allows.
Surveyors then agree an award setting how and when it happens.
Why photograph a Chelsea neighbour’s rooms before work starts?
A schedule of condition records the house before anything changes.
The Act does not require one, but surveyors advise it.
Without one, damage is hard to attribute later.
