Camden's guidance and what it means for a garage
Camden's planning guidance for home alterations is the Home Improvements CPG (Camden Planning Guidance), with the Design CPG (Camden Planning Guidance) behind it for materials, proportions and how a new opening sits in an existing front. We found no figure in Camden's guidance aimed at garages specifically, so a garage is judged under those general tests.
In practice, the front elevation carries the case. A garage door on a Camden street can be part of a terrace, a mews or a purpose-built block, and replacing it changes the whole frontage, not one house. Our drawings show the replacement in context, with the neighbouring doors and windows on the same sheet.
The Amenity CPG (Camden Planning Guidance) adds the neighbour tests: outlook, privacy and daylight to windows nearby. A converted garage rarely changes those, but a new window onto a shared passage can.

Conservation areas, Article 4 and listed buildings
Camden publishes 40 conservation areas and 21 Article 4 directions. Historic England lists 1,971 entries in the borough, and a listed building needs listed building consent for most external changes.
Put those together and a Camden garage conversion can easily need an application. If you stay inside the existing opening and keep the door's appearance, the change may still be acceptable, but you want the council's view in writing. Our planning drawings in Camden set carries the application, and the council fee for a house is £548.
Flats, leases and who owns the garage
Only 13.3 per cent of Camden households live in a house or bungalow. Householder permitted development does not cover flats, so a flat owner's garage conversion needs an application where a house owner's might not.
A lease adds a second approval. A garage in a block, or a mews unit with a shared structure, may be restricted by the lease or need the freeholder's consent. We ask about this at the first call, because it shapes both the drawings and the order of the work.
How Camden decides householder applications
Camden decided 394 householder applications in its latest published year and granted 89.1 per cent. Only 77.7 per cent were decided within eight weeks or an agreed extension, so allow for an extension of time.
Those figures cover every household project and say nothing about a particular garage. We use them for the timetable and the council's own guidance for the design.
Technical drawings for a converted garage
Building Regulations approval is needed in every case. The energy rule is: New elements in existing dwellings, limiting U-values W/(m²·K): roof 0.15, wall 0.18, floor 0.18, windows 1.4 (or WER Band B), doors 1.4. A basement or lower-ground garage adds damp and ventilation questions, and the ventilation rule is: Intermittent extract: kitchen 30 l/s with cooker hood (60 l/s otherwise), utility 30 l/s, bathroom 15 l/s, WC 6 l/s.
A garage that sits under or beside flats also affects fire separation. The detection rule is: All dwellings: fire detection and alarm system minimum Grade D2 Category LD3 (BS 5839-6), mains-operated smoke alarms to BS EN 14604. We coordinate it with the structure above, and our building regulations drawings in Camden show the full technical set.
What we need, what you receive and nearby boroughs
Send us the lease or title if you have it, the decision notice for the property and a photograph of the frontage. We survey the garage on one datum with the floors around it, show you the options in plan and freeze the design in writing. Sheets are normally ready about a week after the survey, and a second chartered technologist checks them.
Garage conversion plans in Camden start at £695 with VAT included, fixed before you commit. If the council asks for changes, we redraw at no charge until approval. Where a house qualifies, a Lawful Development Certificate in Camden records the position.
For the borough as a whole, see architectural drawings in Camden. Creating a separate home is covered by flat conversion drawings in Camden. Next door, compare Islington, Westminster and Barnet, or read the overview of garage conversion plans.

Questions
Do I need planning permission to convert a garage in Camden?
Often, yes. With 40 conservation areas and 21 Article 4 directions, and a housing stock that is mostly flats, many garages fall outside permitted development. We check the address first.
Can I convert a garage that belongs to a block of flats?
Householder permitted development does not cover flats, so an application is usually needed, and the lease may require the freeholder's consent too.
How much do garage conversion plans cost in Camden?
From £695 including VAT, fixed up front. The council fee is paid to the council separately.
How long does Camden take to decide a householder application?
In the latest published year 77.7 per cent were decided within eight weeks or an agreed extension, so allow extra time.
