Measured Building Survey in Hillingdon UB10
Fixed-fee, MCIAT-chartered measured building survey for Hillingdon (UB10) homeowners — London Borough of Hillingdon validation and local constraints handled from the start.
UB10 spans two distinct worlds: the historic village cores of Ickenham and Hillingdon Village, and the large belt of 1930s suburban semis and detached houses around them where most rear and loft projects happen. On the suburban stock the design conversation is about matching established roofline and frontage patterns, which Hillingdon's guidance sets out clearly.
Inside either village conservation area the emphasis shifts to protecting period character around St Giles and St John the Baptist churches, so materials, rooflines and boundary treatments face tighter control. Because the two conservation-area boundaries are compact, we confirm exactly where a UB10 property falls before choosing a permitted-development or full-application route.
Planning in Hillingdon (UB10): what to know before you apply
Most UB10 householder work sits on interwar suburban housing outside the conservation areas, where Hillingdon has well-established expectations for rear depth, side returns and dormers. The Ickenham Village and Hillingdon Village conservation areas are the exceptions — there, heritage-led design and usually a full application are the right approach.
Typical Hillingdon housing stock
Two protected village centres — Ickenham around St Giles Church and Hillingdon Village around St John the Baptist — of period cottages and Victorian houses, ringed by the substantial 1930s semi-detached and detached suburban stock that makes up most of the wider UB10 postcode.

Measured Building Survey for Hillingdon (UB10) 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.
