A measured building survey captures your North Harrow property exactly — every wall, opening, level and boundary — as the accurate base for design and planning drawings. On HA2's older terraced and villa stock around North Harrow, South Harrow, Rayners Lane, West Harrow fringe, walls are rarely square, so a laser-measured survey prevents costly errors before Harrow Council ever sees the application.
Fixed-fee measured surveys across North Harrow from £540 — floor plans, elevations and sections to ±3mm accuracy. Leica Disto laser + BLK360 point-cloud scanning, AutoCAD and Revit deliverables, MCIAT chartered.
Across North Harrow, South Harrow, Rayners Lane, West Harrow fringe in HA2, the dominant property is inter-war bay-fronted semis and terraces around north harrow and south harrow — classic metro-land. That stock shapes what measured building survey looks like here: the right approach for a period terrace differs from a mansion-block flat or a new-build, and Harrow Council judges each on design quality and neighbour impact. We survey the specific North Harrow property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the HA2 streetscape.

Because HA2 is classic 1930s metro-land — bay-fronted semis around North Harrow, South Harrow and Rayners Lane, ideal for rear and side extensions and hip-to-gable loft conversions. With few conservation constraints, much of the work runs on the Permitted Development route, confirmed with a Lawful Development Certificate.
Usually yes — the metro-land semis suit a hip-to-gable plus rear dormer within the 50 cubic metre volume allowance, confirmed by a Lawful Development Certificate. The 1930s roofs generally give good head height. We draw the scheme for Building Control too, which is essential for the new floor and stair.
Often, on the standard semi plots — a wrap-around ground-floor extension or a two-storey side addition, subject to Harrow's design and neighbour-amenity policy on the 45-degree test. We design within those limits and produce the planning and Building Regulations drawings together.
With HA2 houses around £500,000-£775,000 and Metropolitan and Piccadilly line links into central London, a rear extension or loft adds family space worth well above the build and drawing cost. HA2 offers strong metro-land value, and our fixed fee keeps the cost predictable.
Our fixed fee for measured building survey in North Harrow starts at £540 — no hourly billing. With North Harrow property at around £300,000 for a flat and £500,000-£775,000 for a house, the professional drawing fee is a small fraction of the value the work adds to HA2's inter-war bay-fronted semis and terraces around north.

Almost always. Any structural work behind measured building survey in North Harrow — new openings, steel beams, loft floors, foundations — needs Building Regulations approval covering structure (Part A), fire escape (Part B) and insulation (Part L), submitted to Harrow Council Building Control or an approved inspector. On HA2's typically terraced and semi-detached stock, a Party Wall notice to adjoining neighbours is normally required before the steelwork. We coordinate both as part of the Complete package.
In value terms, yes. With North Harrow (HA2) property at around £300,000 for a flat and £500,000-£775,000 for a house, a well-designed extension or loft typically returns more than it costs in added floor area and sale value, while our fixed drawing fee from £540 keeps the professional cost predictable. The bigger risk is an unapproved or non-compliant scheme — which is why council-ready drawings and a clean Building Control sign-off matter on HA2 homes.
