Measured Building Survey in Brook Green W6
Fixed-fee, MCIAT-chartered measured building survey for Brook Green (W6) homeowners — London Borough of Hammersmith & Fulham validation and local constraints handled from the start.
Brook Green in W6 is a sought-after enclave of large Victorian terraces and Edwardian mansion blocks in the green space between Hammersmith and Kensington. Families here typically extend at the rear or into the side return, convert generous lofts, or reconfigure mansion flats, so most of our drawings support space-making projects on characterful period homes.
The Brook Green conservation area and neighbouring designations mean roof alterations, front elevations and materials are all assessed against a strikingly consistent streetscape. We detail schemes to sit comfortably within that grain and present them the way Hammersmith and Fulham's officers expect, which keeps sensitive extensions and loft conversions moving smoothly towards approval.
Planning in Brook Green (W6): what to know before you apply
There is no published householder Article 4 direction we depend on for Brook Green, but the Brook Green conservation area constrains permitted development on roofs and principal elevations. Matching red-brick detail, respecting the scale of the terraces, and checking for protected street trees are the usual design limits on rear and roof works.
Typical Brook Green housing stock
Brook Green is a leafy pocket of large Victorian terraces and red-brick Edwardian mansion blocks set between Hammersmith and Kensington. The generous houses lend themselves to full-width rear extensions, side returns and loft conversions, while the mansion blocks generate careful internal reconfigurations and flat conversions that suit family life in W6.

Measured Building Survey for Brook Green (W6) 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.
