Rear and side dormers to Notting Hill’s stucco terraces — adding headroom and a usable room while keeping the front roofline intact and RBKC on side.

A dormer is usually the most efficient way to add real headroom to a Notting Hill loft: it projects from the roof slope to create full standing height and a square, usable room. On the stucco terraces of the Ladbroke and Pembridge estates the front slope faces the street and the conservation area, so front dormers are normally resisted — the volume is won at the rear or side.
Even a rear dormer needs planning permission here, with a design that stays subordinate to the roof and sits below the established parapet line of the terrace. We size and position the dormer so it reads correctly, does not dominate the original roof, and respects the rhythm of the neighbouring houses.
We assess your specific roof first — pitch, ridge height and party walls — then design a dormer that wins consent and works structurally, with the staircase, fire strategy and Building Control handled in one contract.
Where the dormer can go — and how big — is set by RBKC roofline policy.
On the street elevation a dormer harms the conservation roofline, so the room is gained at the rear or side.
RBKC expects a dormer set below the parapet and in from the edges, framed to sit quietly on the roof.
A dormer in the conservation area needs a formal application and a roof study showing it is not prominent.
A new floor needs steel support, a compliant staircase and a fire strategy — engineered in-house.
From a roof feasibility study to a finished, weather-tight room — under one team.
Measuring pitch, ridge and head height to confirm a dormer delivers usable space.
