Planning Permission & Building Regulations in Belgravia.
Whether a project in Belgravia needs planning permission, and how difficult that permission is to obtain, depends on the property: whether it is in a conservation area, whether it is listed, whether it is a flat with a freeholder, and whether the council has removed permitted development rights on the street. We check all of this at the first visit and tell you the route before any drawings are made.
We then prepare and submit whatever is needed to the City of Westminster: a householder application, a lawful development certificate for permitted development, listed building consent with a heritage statement, or prior approval for a larger extension. Building regulations are handled through an approved inspector or the council's building control, and party wall notices are served where a neighbour's structure is affected.
Because our architects prepare the drawings and our team builds from them, there is no handover between designer, agent and builder. One team is responsible for getting the approval and for building what was approved.

Belgravia: the houses and the planning rules.
Belgravia was built by Thomas Cubitt for the Grosvenor estate in the 1820s and 1830s and it has barely changed since: cream stucco terraces around Eaton Square, Belgrave Square and Chester Square, with cobbled mews behind. The whole district is a conservation area, most houses are listed, and the Grosvenor estate remains the freeholder of much of it.
Work here is nearly always to a listed building, which means listed building consent, a heritage statement and an approach that treats the historic fabric as the priority. Within that we fit kitchens, bathrooms, joinery and services to modern standards, and convert mews houses into complete homes.
The Belgravia Conservation Area covers the whole district, and the majority of the houses are Grade II or II* listed.
Westminster City Council
Westminster decides planning and listed building applications for the whole of Belgravia, with detailed conservation area guidance and long-standing policies on roof extensions and basements.
Grosvenor estate
Grosvenor's own consent is required for most alterations on the estate, with its own design guidance and surveyors.
Listed interiors
Cornices, staircases, chimneypieces and joinery are part of the listing; changes need consent and specialist trades.

It depends on the property and the proposal. Permitted development covers many rear extensions and lofts, but not in flats, listed buildings or where Article 4 directions apply. We confirm the route at the first visit.
