Measured Building Survey in Greenwich
Fixed-fee, MCIAT-chartered measured building survey for Greenwich homeowners — Royal Borough of Greenwich validation and local constraints handled from the start.
Greenwich stretches from the Georgian streets of West Greenwich and the Georgian-fringed heath at Blackheath — set against the Maritime Greenwich World Heritage Site — out to the Edwardian villas of Westcombe Park and the interwar and post-war suburbs of Eltham and Kidbrooke. The northern, historic core carries strong conservation and protected-view control, while the outer suburbs and newer riverside development along the Thames offer more generous plots for extensions and lofts. The right route depends heavily on where in the borough you are.
The character shifts street by street. Conservation areas at West Greenwich, Ashburnham Triangle, Blackheath, Westcombe Park, Eltham Park and Woolwich each carry design control over materials, rooflines and front elevations, and the sloping sites around Blackheath and the Greenwich hills shape what an extension can be. Protected views toward the Royal Observatory and across the river, together with Article 4 directions on HMO conversions in parts of the borough, mean the constraints on a heritage-led scheme in the historic core differ sharply from a straightforward suburban addition toward Eltham or Charlton.
We prepare Greenwich planning drawings tuned to the specific area — heritage-led applications around West Greenwich and Blackheath, and simpler extension and loft schemes toward Eltham and Kidbrooke — confirming the World Heritage Site setting and conservation designations for your address first. It is the same council-accepted drawing set an architect would prepare, usually at around 30% less, with a fixed fee agreed up front, a roughly seven-day drawing turnaround and free redraws until the Royal Borough of Greenwich approves. Most householder applications are decided within the statutory eight-week period once validated, so we draw to the council's validation checklist from the start.
Planning in Greenwich: what to know before you apply
A distinctive Greenwich consideration is the Maritime Greenwich World Heritage Site and its buffer zone, where the council protects townscape and long views toward the Royal Observatory — proposals nearby are assessed against that setting. Conservation-area control in West Greenwich, Blackheath and Westcombe Park, and Article 4 directions on HMO conversions in parts of the borough, also apply. We confirm what affects your address before drawing.
Typical Greenwich housing stock
Georgian and early-Victorian terraces around West Greenwich and Blackheath, Edwardian villas in Westcombe Park, interwar and post-war housing toward Eltham and Kidbrooke, and newer riverside development along the Thames.

What Greenwich is actually built of
Building form decides the survey scope. Attached housing means party-wall lines and neighbouring returns have to be picked up accurately because they constrain everything after; a detached plot usually needs the boundary and levels instead. These are measured counts from Ordnance Survey building data, not a description of the borough.
Greenwich building stock
Residential building form across 5 of Greenwich's 5 postcode districts, from 2,159 classified buildings. Connectivity is topology: a semi extended into its garage reads as attached on more than one side.

Measured Building Survey for Greenwich 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.
