Measured Building Survey in Highgate N6
Fixed-fee, MCIAT-chartered measured building survey for Highgate (N6) homeowners — London Borough of Camden validation and local constraints handled from the start.
Highgate (N6) sits on the hill above Camden with two overlapping conservation areas — Highgate and Highgate Village — covering the historic core of Georgian houses and Victorian villas along the High Street and Southwood Lane. It is one of the few London districts where the topography is a planning constraint in its own right, not just a construction one.
Camden's Basements Article 4 direction applies here, which removes permitted development rights for basement works and means any lower-ground scheme in N6 needs a full planning application supported by proper drawings. Add the steep slopes toward Swains Lane, the mature tree cover through the village, and the conservation-area control over frontages and rooflines, and Highgate projects need level and tree information on the drawings from the outset. We survey the slope and check the conservation-area boundary before designing to Camden's guidance.
Planning in Highgate (N6): what to know before you apply
N6 is covered by Camden's Basements Article 4 direction, so permitted development rights for basement works are removed and a full application is required — a material difference from most outer-London districts. The Highgate and Highgate Village conservation areas control the historic core's frontages, rooflines and materials, while the Highgate Hill topography and the village's mature tree cover mean level changes, retaining structures and tree protection are routinely assessed on N6 householder schemes.
Typical Highgate housing stock

Measured Building Survey for Highgate (N6) homes: the package and the process
A measured survey is the foundation every later drawing is checked against. We record the building as found — floor plans, elevations, sections, levels and, where needed, the position of structure and services — to a stated tolerance, so nothing downstream rests on an assumption about what is there.
The deliverable is chosen for what happens next. A conversion or extension design wants a layered CAD file that a designer can build on; a party wall or dilapidations matter wants dimensioned PDFs that stand on their own as a record. We agree that before the survey, because it changes what we capture.
Survey effort follows the building, not the floor area. A regular detached house measures quickly; a terrace with a rear outrigger, split levels, and a century of alterations takes longer because the survey has to record what was actually built rather than what the plan form implies.
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.
Can I reuse an old survey or estate agent floor plan instead?
Generally, no — estate agent floor plans are produced for marketing purposes and are not dimensionally accurate enough to design an extension or loft conversion against, and a previous owner's drawings may not reflect alterations made since, or may simply be inaccurate to begin with. A fresh measured survey is a modest cost relative to the overall project and is the single best way to avoid a redesign once a builder is on site and finds the real dimensions differ from the drawings.
