Loft Conversions in St John's Wood.
A loft conversion adds a bedroom and bathroom without touching the garden, and in most of St John's Wood it is the most cost-effective way to gain a floor. Which type suits your house depends on the roof: Victorian and Edwardian terraces usually take a rear dormer, 1930s semis with hipped roofs need a hip-to-gable conversion to make the space usable, and in conservation areas a mansard or rooflight scheme may be the only option.
We start by measuring the roof. About 2.2 metres from the top of the joists to the ridge is needed for a comfortable room; we check this at the first visit before anything is drawn. From there our architects design the layout and the stair, our engineers design the new floor and any steelwork, and our team builds it with the house occupied throughout.
Most lofts are permitted development within the 40 or 50 cubic metre allowance, with the dormer at the rear. Flats, listed buildings and streets with Article 4 directions need a planning application, and every loft needs building regulations approval for the structure, fire escape and insulation. We manage all of it.

St John's Wood: the houses and the planning rules.
St John's Wood was London's first garden suburb of villas, laid out from the 1820s, and much of that character survives: paired stucco villas set back behind front gardens, later Victorian houses on the roads towards Maida Vale, and the mansion blocks and 1930s apartment buildings along Wellington Road and St John's Wood Road. Abbey Road and Lord's sit at its edges, Regent's Park to the south.
For owners that means large, well-proportioned rooms, deep plots that suit rear extensions and basements, and a planning authority, Westminster, that expects any change to respect the villa character. We have fitted kitchens on Abbey Road and in the roads off the High Street, and we know which streets carry the tighter controls.
The St John's Wood Conservation Area covers most of the district.
Westminster City Council
Westminster decides planning and listed building applications. The St John's Wood Conservation Area removes some permitted development rights, so many rear extensions and roof changes need a full application.
Villas and gardens
Extensions are judged on their effect on the villa form and on garden space; basements need a Basement Impact Assessment under Westminster's basement policy.
Flats and mansion blocks
Refurbishing a flat usually needs a licence to alter from the freeholder or block management in addition to building regulations.

Loft Conversions in St John's Wood: your questions.
Is a loft conversion in St John's Wood permitted development?
Often, provided the added volume is within 40 cubic metres for a terrace or 50 for other houses and the dormer is at the rear. Flats, listed buildings and streets with Article 4 directions need an application to the City of Westminster.
How much headroom do I need for a loft conversion?
About 2.2 metres from the top of the ceiling joists to the ridge. Victorian and Edwardian roofs usually have it; 1930s hipped roofs often need a hip-to-gable conversion to make the space usable. We measure at the first visit.
