Dormer and mansard loft conversions to Holland Park's period houses — designed to win RBKC consent within the conservation areas, with structure, staircase and party wall handled in-house.

A loft conversion in Holland Park has to respect a protected roofline. Most of W11 lies within the Royal Borough of Kensington & Chelsea's conservation areas, and many terraces already carry a uniform mansard or parapet line that the council expects to be preserved — so roof additions are carefully controlled, and on listed buildings they may be limited altogether.
Where the building and the conservation area allow, we design dormer and mansard conversions that read correctly from the street, add a genuine usable floor, and integrate a compliant staircase and fire strategy. Structural engineering, party wall agreements and Building Control are all handled in-house.
We assess feasibility for your specific roof first — there is no point designing a conversion RBKC will refuse.
Roofline policy, listing and structure decide what is possible in W11.
Conservation areas protect the established roof and parapet line; a mansard or dormer must read correctly from the street to win consent.
On listed buildings, roof alterations may be restricted or refused — we assess this before designing anything.
Roof changes in conservation areas need a formal planning application and a careful heritage-led design.
A new floor needs structural support, a compliant staircase and a fire strategy — all engineered and signed off in-house.
