Floor Plans in Hampstead NW3
Fixed-fee, MCIAT-chartered floor plans for Hampstead (NW3) homeowners — London Borough of Camden validation and local constraints handled from the start.
Hampstead (NW3) is, in permitted-development terms, close to a special case. Three conservation areas cover the district — Hampstead, Belsize and Fitzjohns/Netherhall — and Camden has attached a non-immediate Article 4 direction to each of them, on top of the borough-wide Basements direction. The practical effect is that very little in NW3 proceeds under permitted development.
That reshapes what a project looks like here. Basement works need a full application under the Basements direction; the non-immediate Article 4 directions across Hampstead (excluding Frognal Way), Belsize and Fitzjohns/Netherhall strip further rights inside those conservation areas; the village core carries a very high concentration of listed buildings needing listed building consent alongside planning; and because so many of the large Fitzjohns Avenue and Belsize Park villas were long ago converted into flats, a large share of NW3 work is flat alteration — where permitted development rights do not exist in the first place. We establish the designation, listing and tenure position for an NW3 address before drawing to Camden's guidance.
Planning in Hampstead (NW3): what to know before you apply
NW3 is one of the most heavily restricted districts in London for householder work. Camden's Basements Article 4 direction removes permitted development rights for basement schemes, and non-immediate Article 4 directions apply across all three conservation areas — Hampstead (excluding Frognal Way), Belsize and Fitzjohns/Netherhall — removing further rights inside them. The village core has a very high concentration of listed buildings requiring listed building consent, and the widespread conversion of the large villas into flats means many NW3 projects have no permitted development rights regardless of designation. Assume a full application in NW3.
Typical Hampstead housing stock
Georgian houses in the old village core, substantial Victorian red-brick villas along Fitzjohns Avenue and Netherhall Gardens, and large Victorian semi-detached and terraced houses through Belsize Park, much of it converted to flats.

Floor Plans for Hampstead (NW3) homes: the package and the process
A floor plan is only as good as the survey behind it. Room dimensions taken from a laser survey rather than an estate agent's sketch, wall thicknesses drawn as they actually are, and structural walls distinguished from partitions — those are what make a plan usable for design work rather than just for marketing.
We issue plans at a stated scale with a scale bar, so they stay measurable when printed or resized, and supply them in formats that work for the next stage: a PDF to share, and CAD where an architect, engineer or kitchen designer needs to draw on top of it.
The plan itself carries the building's history. Chimney breasts, blocked openings, changes in floor level and an outrigger that has been extended more than once all show up in a measured plan, and they are precisely the things a sketched plan leaves out.
What are floor plans used for?
Floor plans serve several distinct purposes in London property: estate agents use them to market a sale or letting alongside photographs, giving buyers and tenants an accurate sense of layout and scale that a floor plan on its own can convey better than photos; solicitors and lenders often require a lease plan showing the demise of a flat within a building, particularly for leasehold sales or re-mortgages; landlords use them to document a property's layout for reference, insurance or portfolio management; and homeowners use them simply to have an accurate record of their existing layout, whether for their own reference or as the first step before considering any building work.
How accurate are laser-measured floor plans?
We measure every floor plan on site using a laser distance meter rather than a tape measure or estimation from photographs, which keeps room dimensions, wall thicknesses and door and window positions accurate to within a few millimetres. This matters more than it might seem: an estate agent's marketing plan that overstates a room's size can mislead a buyer and cause problems at survey stage, while a lease plan used for legal purposes needs to accurately reflect what a leaseholder actually owns. A laser-measured plan also means that if you later want to use it as the existing-layout drawing for a planning application, it is already accurate enough to build proposed drawings on top of, rather than needing to be re-measured.
How much do floor plans cost in London?
A single floor-plan set starts from £450, which covers a laser-measured site visit and scaled, dimensioned drawings of each floor of the property. The exact fee depends on the number of floors, the overall size of the property, and whether you need elevations or a site plan in addition to the floor plans themselves — for example, for a lease plan or as the base for a future planning application. This is a fixed fee agreed upfront, with no hourly billing.
