Measured Building Survey in Kensington & Chelsea
Fixed-fee, MCIAT-chartered measured building survey for Kensington & Chelsea homeowners — Royal Borough of Kensington and Chelsea validation and local constraints handled from the start.
The Royal Borough of Kensington and Chelsea is one of the most design-controlled authorities in the country: a very high proportion of its grand stucco-fronted townhouses, garden-square terraces, red-brick mansion blocks and cobbled mews houses are listed or sit within conservation areas. Designations such as Kensington, Chelsea, Ladbroke (Notting Hill), Holland Park, Brompton and Earl's Court Square carry detailed material and elevation control, so applications succeed on the strength of precise, heritage-led drawings rather than standard templates.
Permitted development can rarely be assumed here. Near-comprehensive conservation-area coverage across Kensington, Chelsea, Notting Hill and South Kensington and a high density of listed buildings mean a full planning application, and often listed-building consent for internal as well as external changes, is usually required even for modest works. The borough's basements policy is nationally known for restricting new basements, generally to a single storey, and controlling excavation extent alongside a basement impact assessment. A basement or extension can still be viable, but every scheme in Holland Park, Earl's Court or World's End must be designed to policy from the outset.
We prepare Kensington & Chelsea planning and listed-building submissions that respond to the borough's townscape and its restrictive basement and conservation policies, confirming the exact designations and listing status for your address before any design begins. You get a fixed fee agreed up front, the same council-accepted drawings an architect would produce for usually around 30% less, a roughly seven-day drawing turnaround and free redraws until the council approves. Most householder applications are determined within the statutory eight weeks once validated, though listed-building and basement cases attract more consultation, so a validation-first approach matters.
Planning in Kensington & Chelsea: what to know before you apply
In Kensington & Chelsea, permitted development can rarely be assumed: near-comprehensive conservation-area coverage and a high density of listed buildings mean a full planning application — and often listed-building consent — is usually required even for modest works. The borough's basements policy generally limits new basements to a single storey and controls their extent. We confirm every constraint up front.

Measured Building Survey for Kensington & Chelsea homes: the package and the process
Every measured building survey we prepare for a Kensington & Chelsea property is drawn to Royal Borough of Kensington and Chelsea’s validation standards and tuned to the local 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.
