Garage Conversion Drawings in Greenwich SE10
Fixed-fee, MCIAT-chartered garage conversion drawings for Greenwich (SE10) homeowners — Royal Borough of Greenwich validation and local constraints handled from the start.
Greenwich (SE10) is among the most heritage-sensitive places to build in London: most of its period housing sits within one of the Royal Borough's conservation areas — West Greenwich, Greenwich Park, East Greenwich or the Ashburnham Triangle — and three of those carry Article 4 directions that pull nearly all external work into the planning system. Side-return and rear extensions on the Victorian and Georgian terraces are the staple, but they are judged carefully on materials, proportion and detail.
SE10 also sits within, or beside, the Maritime Greenwich World Heritage Site: the inscribed core is the Old Royal Naval College, Queen's House, Royal Observatory and Cutty Sark, with the surrounding streets in the buffer zone. That means townscape and setting weigh heavily on how schemes are assessed. We check exactly which conservation area — and which Article 4 direction — applies to a Greenwich address before advising on a permitted-development or full-application route.
Planning in Greenwich (SE10): what to know before you apply
Most SE10 houses fall inside the West Greenwich, Greenwich Park, East Greenwich or Ashburnham Triangle conservation areas, and the first three carry Article 4 directions removing permitted-development rights for re-roofing, windows, doors and other external changes. The Maritime Greenwich World Heritage Site and its buffer zone add further townscape scrutiny. We confirm the conservation area and Article 4 status for a specific property before recommending a route and drawing to the Royal Borough's guidance.

Garage Conversion Drawings for Greenwich (SE10) homes: the package and the process
Every garage conversion drawings we prepare for an Greenwich property is drawn to Royal Borough of Greenwich’s validation standards and tuned to the SE10 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.
A garage conversion is usually the cheapest way to add a room in London, because the walls, roof and slab already exist — but the drawings still have to solve problems that a garage was never built to answer. The floor sits lower than the rest of the house and often has no damp-proof membrane, the door opening has to become a proper insulated wall, and whether the project needs planning permission at all depends on your borough, your estate and your specific property, not just the general permitted development rules.
DrawingsDirect checks your permitted development position first, free, before drawing anything. Where planning is genuinely needed — because of an Article 4 direction, a restrictive planning condition on the original estate, or a change to the building's external appearance — we prepare a full householder application; where it is not, we go straight to building regulations. Structural work, insulation and ventilation are designed in-house at a fixed fee either way.
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.
| Route | Trigger | Planning position | Fee from |
|---|---|---|---|
| Straightforward permitted development conversion | No footprint or roofline change | Lawful Development Certificate optional, building regs required | £1,100 |
| Article 4 area or restricted estate | Permitted development rights removed | Householder planning permission needed | £1,600 |
| Garage conversion combined with an extension | Footprint enlarged beyond the garage | Full planning plus structural calculations | £2,200 |
