Floor planning in Harrow: a measured survey, then accurate plans
Floor planning in Harrow starts with a measured survey of your home, from which we draw accurate existing floor plans to scale. The fixed fee starts at £275. Our MCIAT chartered architectural technologists prepare plans that work for a sale, a letting or the first stage of a planning application to Harrow Council.

A scaled floor plan shows every room as it really is
A floor plan from us is a measured drawing, not a sketch. Each floor of the house is set out to scale with its walls, doors, windows, stairs and fixed fittings in the right place, and each room is labelled so anyone reading it can follow the layout.
Agents and landlords use these plans to describe a property clearly. Homeowners thinking about an extension or a loft use them as the base drawing, because every proposed plan is drawn over an accurate record of what is there now.
Everything is measured on site before anything is drawn
One of our team visits the house and measures it room by room, recording wall thicknesses, openings and the position of stairs and chimney breasts. Taking the measurements ourselves means the plans reflect the building, not an old estate agent's brochure.
Back at the desk, the survey is drawn up as clean existing plans. If you later need a full measured building survey in Harrow with elevations and sections, the same site record is the starting point.
Over the latest eight quarters the council determined 217 of these prior approvals and refused 171, while 571 notifications were found not to need prior approval at all.
The fee is fixed and agreed before the visit
Measured survey and floor plans start from £275. That figure is the starting point on our price list; we confirm the fixed fee for your property before the survey is booked, so the price you agree is the price you pay.
There is no hourly charge and no surprise invoice after the visit. If you go on to commission planning drawings, the existing plans are already done.
Extending later? Harrow Council grants most householder applications
Harrow Council decided 917 householder applications over the latest four quarters, according to our analysis of MHCLG planning application statistics, and 82% of them were granted. On timing, 95% of those decisions (leaving out prior approvals) were made within the eight-week target period.
Those figures describe what the council has done, not what will happen to any one application. They do show why the existing plans matter: an application is judged on its drawings, and drawings built on a measured survey leave less room for queries about the starting point. Our planning permission page for Harrow covers that next step.
Larger rear extensions and certificates tell a different story
The larger home extension prior approval route is far less forgiving in Harrow. Over the latest eight quarters the council determined 217 of these prior approvals and refused 171, while 571 notifications were found not to need prior approval at all. Over the same period Harrow Council decided 704 certificates of lawful development, a route many owners use to confirm that work falls within permitted development.
Appeals are a record, not a forecast. The Planning Inspectorate Casework Database shows 320 householder appeals from the borough decided as allowed or dismissed, of which 137 were allowed. The underlying national tables are published on GOV.UK.
