NU Projects is a design and build company in Fulham SW6, founded in 2010. We handle design and build in Chelsea SW3, under one contract. The calculator gives your own range in a minute, by scope and finish. Call 020 7731 6841, and a budget estimate typically follows within seven days.
Chelsea runs along the river, a short ride from our Fulham studio. Its stock is Georgian and Victorian terraces, often four storeys, sometimes five. Garden squares sit among them.
Here a whole house brief usually touches every floor, and often goes down. So design, engineering and cost are settled together, never handed between firms.
Our architectural designers draw it, working with ARB-registered architects we partner with. Matt Coverley, our quantity surveyor, prices each drawing as it develops. A budget estimate typically follows within seven days. A line by line cost plan comes next.
We have completed houses across Chelsea. One townhouse gained a basement under its whole footprint. Above, it opened up beneath a long rooflight. A terrace was renovated over four floors, with a cinema room.
What the borough asks of a Chelsea house.
- Council
- Royal Borough of Kensington and Chelsea. Its Local Plan dates from July 2024.
- Conservation
- Roughly three quarters of the borough is protected. Outline applications are not accepted there.
- Going down
- Policy CD11 allows a single storey. It may sit under half the garden, no more.
- Going back
- Policy CD13 holds additions to the neighbours’ rear line, below the eaves.
- Going up
- Policy CD12 resists an extra storey where a terrace roofline is complete.
- Listed fabric
- Consent reaches inside where work touches historic fabric. Policy CD5 counts the order of rooms.

Further reading, from the journal
Is design and build suited to a Chelsea townhouse?
Very much so. Structure, basement and finishes are decided together.
One team carries the drawings, the price and the build.
Can a Chelsea design and build add a storey?
Rarely. Policy CD12 resists one where the roofline is unbroken.
We read the whole terrace before proposing it.
Who prices a Chelsea design and build?
Matt Coverley, our in-house quantity surveyor.
He measures from the drawings and shows every line, open book.
Does a listed Chelsea house limit the design?
It shapes it. Consent covers inside work touching historic fabric.
No basement may be dug under a listed building.
Have you designed and built in Chelsea before?
Yes, several, each shown on our projects page.
They include a new basement, a kitchen extension and a four floor renovation.
