GS Renovation works on roof level projects in Kensington, where W8 combines white-stucco townhouses, red-brick period houses and a large number of mansion flats. The Royal Borough of Kensington and Chelsea protects almost all of it through conservation area designation and listing, so consent leads the programme and the mansard is the form most often under discussion.
Townhouses, mansard policy and W8 roofscapes
Where you own a whole townhouse in Kensington, a mansard is normally the form under discussion, because it recovers full height across the plan and sits within an established roof profile in a way a box dormer never will. The Royal Borough of Kensington and Chelsea takes a close interest in roof extensions and will look at the terrace as a group: whether mansards already exist along it, how a new one lines through, and how it reads in longer views.
Permitted development plays no part here. Conservation area designation removes it and listing removes it, so a mansard means full planning permission, and on a listed building a separate listed building consent judged on the effect of the work on the building's special interest. Slate, lead, dormer proportions and window pattern all get examined in detail. That is a heritage architect's territory, and GS Renovation builds to the drawings they get approved.
Mansion flats and the honest answer in Kensington
A large share of W8 is not houses at all but period mansion flats and converted townhouses. In those, the roof and the structure belong to the freeholder rather than to you, so a loft conversion is usually not possible, and where a top floor lease does include roof space the freeholder's consent, a licence to alter and a full planning application would all be needed first. We say this plainly rather than take a survey fee for a scheme that will not run.
What does work in a Kensington flat is internal: removing or forming openings with engineer-designed steels, reconfiguring a top floor within its existing volume, upgrading acoustic separation, and full refurbishment. All of it still needs the landlord's consent under the lease and building control approval. In a house, we handle the whole chain, from the engineer's steel design and padstone bearings to the party wall notices your neighbours on both sides will receive.
- Building control inspections booked at floor, steel and completion
- Party Wall notices prepared for the building owner to serve
- Head height and ridge survey before design
- Protected stair enclosure and fire doors to Part B
- Rooflight conversions where the roof line must not change
