Garage Conversion Drawings in East Dulwich SE22
Fixed-fee, MCIAT-chartered garage conversion drawings for East Dulwich (SE22) homeowners — London Borough of Southwark validation and local constraints handled from the start.
East Dulwich (SE22) sits in the London Borough of Southwark, tucked between Dulwich Village, Peckham and Forest Hill. Its character comes from the tight grid of late-Victorian and Edwardian terraces — the 'Derbyshire colony' of streets off Lordship Lane, including Melbourne Grove, built in the 1870s and 1880s. Rear, side-return and loft projects on these consistent terraces are the staple here.
The Gardens conservation area lies to the north-east, off East Dulwich Road by Peckham Rye Common, and the Dulwich Village conservation area borders the district to the south, so properties near either boundary answer to heightened design scrutiny. Southwark publishes its Article 4 directions and none covers these householder streets, so many East Dulwich houses keep permitted-development rights — we confirm where an address sits relative to the conservation areas before advising.
Planning in East Dulwich (SE22): what to know before you apply
Southwark publishes its Article 4 directions and none covers the East Dulwich householder streets, so many houses retain permitted-development rights for rear and loft work. The Gardens conservation area to the north-east and the Dulwich Village conservation area to the south are the controls that matter near those boundaries, and the consistent Victorian and Edwardian terrace frontages mean dormers and elevation changes are judged against the established grain. We check an address against those designations before drawing.

Garage Conversion Drawings for East Dulwich (SE22) homes: the package and the process
The visible change is the front elevation, and that is what the drawings lead on: the garage door replaced by wall and window, drawn with the brickwork bonding, cill line and window proportion set out so the infill reads as part of the house rather than as a blocked opening.
Behind it the work is technical. The existing slab is rarely insulated or damp-proofed to habitable standard, the walls are often single-skin, and the drawings have to show the new floor build-up, insulation line and any structural work over the old opening for Building Control to sign off.
The conversion needs a garage attached to or inside the house, which is largely a feature of interwar and post-war semis and detached stock. A detached garage down the garden is a different project: converting it is an outbuilding question, not an extension of the house.
Is converting a garage permitted development in London?
Converting an integral or attached garage into habitable space, within the existing footprint and without changing the roofline, is often permitted development, meaning no planning application is required. It has to remain within the existing building envelope — extending the footprint, adding height, or altering the roof pushes the project into full planning permission instead. We assess your specific garage against these limits before recommending a route.
Even where a project is permitted development, many homeowners still ask us for a Lawful Development Certificate — a formal confirmation from the council that the works do not need planning permission. It is optional rather than compulsory, but it is useful evidence for mortgage lenders, buyers' solicitors and building insurers later on, and we can prepare the application alongside the building regulations drawings at no great extra delay.
Article 4 directions and other restrictions on garage conversions
Permitted development rights are not universal across London. An Article 4 direction removes them for a defined area — common in conservation areas and some suburban estates — meaning a garage conversion that would be permitted development elsewhere needs a full planning application there instead. Separately, some estates built with planning conditions attached to the original permission restrict garage conversions regardless of Article 4, usually to protect the street's parking or appearance. A conveyancing pack or the original planning decision notice for the house will sometimes reveal a condition of this kind, so we ask to see it where one exists rather than assuming the general permitted development rules apply. We check both before you commit to a route.
What building regulations apply when you convert a garage into living space?
A garage floor typically sits below the damp-proof course of the rest of the house and was never insulated, so the drawings specify a new insulated floor build-up and damp-proofing detail that ties into the existing structure without raising the floor level awkwardly against internal doors.
Part L thermal standards apply to the new walls, floor and any replacement roof covering, and habitable rooms need adequate ventilation — background trickle vents plus extract in wet areas — designed into the drawings rather than left to the builder to improvise on site.
Where the garage sits directly beneath a bedroom or other habitable room, or shares a wall with the main house, fire separation between the new room and the rest of the property also needs checking, since garages are sometimes built to a lower fire standard than the house itself. We review this on a case-by-case basis as part of the same building regulations package.
