Measured Building Survey in Hampstead NW3
Fixed-fee, MCIAT-chartered measured building survey 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.

Measured Building Survey for Hampstead (NW3) homes: the package and the process
Every measured building survey we prepare for an Hampstead property is drawn to London Borough of Camden’s validation standards and tuned to the NW3 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.
Every accurate drawing starts with an accurate survey. Before any proposed extension, loft conversion or alteration can be designed, we need to know exactly what already exists — the true dimensions of each room, the position and size of every door and window, floor-to-ceiling heights, wall thicknesses, roof pitches and the exact shape of the plot. A measured building survey captures all of this on site using a laser distance meter, recording existing plans, elevations and sections to millimetre accuracy, rather than relying on old estate agent floor plans, a previous owner's drawings, or rough on-site guesswork.
This matters more than it might seem. A design drawn on top of an inaccurate existing survey can look correct on paper and then not actually fit once a builder is on site — a wall that is 200mm out of position, a ceiling height that is lower than assumed, or a roof pitch that does not match reality can all force a costly redesign mid-build. A fresh, laser-measured survey de-risks that from the outset: the proposed extension, loft conversion or internal alteration is designed against the real dimensions of your home, not an approximation, so what is drawn is what can actually be built.
Why does a planning or building regulations application need a measured survey?
A planning or building regulations application needs to show the existing building accurately alongside the proposed changes, so the council or Building Control can judge the impact of the work against what is actually there. Existing plans, elevations and sections drawn from an accurate measured survey give the borough confidence that the proposal has been designed against real dimensions, and give your builder a reliable set of drawings to price and build from — an application based on inaccurate or assumed dimensions risks queries, delays, or a design that does not translate cleanly on site.
What does a measured building survey capture?
The survey records everything needed to produce accurate existing drawings: internal room dimensions and floor-to-ceiling heights on every level, the position, width and height of every door and window, wall thicknesses, staircase dimensions and headroom, roof shape and pitch, chimney breasts and structural features, and the external footprint and boundary relationship of the property. Where relevant to the project, we also record ground levels, existing drainage runs and neighbouring boundary conditions.
This is captured with a laser distance meter rather than a tape measure, which keeps the survey accurate to within a few millimetres across a whole property and removes the cumulative measuring error that can creep into a hand-measured survey of a larger or more complex building.
