Planning Permission & Building Regulations in Marylebone.
Whether a project in Marylebone 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.

Marylebone: the houses and the planning rules.
Marylebone is where Space Cucina started, as a kitchen company on Seymour Place. The district is a grid of Georgian and early Victorian streets laid out by the Portman and Howard de Walden estates: flat-fronted brick terraces, stucco around the squares, mews houses behind, and the great mansion blocks of Marylebone Road and Baker Street.
Most of the housing is now flats, from mansion-block apartments to lateral conversions across two houses, which makes refurbishment here as much about approvals and logistics as about design: licences to alter, estate consent, parking suspensions and lift access all shape the programme. We have refurbished bathrooms on Marylebone Road and fitted kitchens for clients across the district.
The Portman Estate, Harley Street and Dorset Square conservation areas cover almost all of it.
Westminster City Council
Applications go to Westminster. Almost the whole district is within conservation areas, and many terraces are Grade II listed, so internal changes to listed houses need listed building consent.
Estate consent
On the Portman and Howard de Walden estates, the freeholder's own approval is needed in addition to planning, with their own design guidance for windows, roofs and rear elevations.
Mansion flats
Block rules govern working hours, deliveries and noise. We plan the programme around them and coordinate with the managing agent.

Planning Permission & Building Regulations in Marylebone: your questions.
Who decides planning applications in Marylebone?
The City of Westminster. Householder applications are normally decided within eight weeks of validation; listed building consent runs to the same timescale unless Historic England is consulted.
Do I need planning permission in Marylebone?
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.
