Article 4 & conservation areas — check before commissioning drawings
Many London boroughs have Article 4 directions removing Permitted Development rights, and inner-London conservation areas (large parts of Hackney, Islington, Camden, Haringey and Waltham Forest) require a full householder planning application even for a rear dormer. We check your specific address against the local plan for free before any drawings start.

Recent London projects
A small selection of loft conversions we've designed across London.
“We're in a conservation area so we expected the planning side to be a headache. Loft Plans handled the lot — drawings, structural calcs and the full submission — and the L-shape dormer was approved first time.”
Loft conversions across every London borough
We've delivered loft conversions across inner and outer London — Enfield, Haringey, Hackney, Islington, Camden, Waltham Forest, Redbridge, Newham, Barnet, Brent and beyond. We know the typical roof structures of London housing stock and how to maximise usable space within planning constraints.
L-shape, dormer & mansard conversions
London's Victorian and Edwardian terraces are perfect for L-shape dormer conversions — adding a double bedroom plus a shower room. Mansard conversions are common in conservation areas where a standard dormer wouldn't be approved. We design what works for your roof and your council.

Get in touchWorking with London planning authorities
Many London boroughs have Article 4 directions removing Permitted Development rights, plus large conservation areas. We check your address against the local plan, advise on what's likely to be approved, and submit the correct application — planning permission, lawful development certificate or both.

Frequently asked questions
Which London boroughs do you cover?
We work across Greater London — including Enfield, Barnet, Haringey, Waltham Forest, Redbridge, Havering, Newham, Hackney, Islington, Camden and the inner boroughs. Each borough has its own planning policies, and we handle the submission for your specific council.
Do I need planning permission for a London loft conversion?
Many London loft conversions are Permitted Development, but Article 4 directions, conservation areas and flats often require a full planning application. We check your address against the local plan during the survey.
Can you do L-shape loft conversions on Victorian terraces?
Yes — L-shape dormers are one of the most popular conversions for Victorian and Edwardian terraces across London. They typically deliver a double bedroom plus a shower room over the original back addition.
How long do London loft conversion plans take?
Survey within 3 days (subject to access), first-draft drawings within 7 days, then structural calculations shortly after. Planning decisions usually take around 8 weeks from submission.
