Floor Plans in Merton
Fixed-fee, MCIAT-chartered floor plans for Merton homeowners — London Borough of Merton validation and local constraints handled from the start.
Merton runs from the sought-after Victorian villas and terraces of Wimbledon Village and South Wimbledon and the planned John Innes estate at Merton Park down through the interwar semis of Raynes Park and Morden to the historic Cricket Green at Mitcham and the streets of Colliers Wood. Loft conversions and rear extensions are the borough's signature projects, with strong conservation control around Wimbledon and Merton Park tightening design where it applies.
The character shifts across the borough. Conservation areas at Wimbledon Village, Wimbledon Common, the John Innes estate at Merton Park, Mitcham Cricket Green, Colliers Wood and Wimbledon West Side control materials, rooflines and front elevations, and the John Innes estate's distinctive Arts-and-Crafts character is protected especially closely, with permitted development often restricted there. Article 4 directions remove permitted development for HMO conversions in designated wards, and toward Raynes Park and Morden the council expects extensions to respect the consistent interwar building lines. Those interwar semis, however, frequently retain permitted development rights for rear extensions and lofts.
We prepare Merton planning drawings that respect the character of the specific area — the Arts-and-Crafts detailing of Merton Park, the villa streets of Wimbledon, and the suburban lines of Raynes Park and Morden — checking permitted development eligibility and any Article 4 or conservation constraint first. It is the same council-accepted drawing set an architect would produce, usually at around 30% less, with a fixed fee agreed up front, a roughly seven-day drawing turnaround and free redraws until the London Borough of Merton 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 outset.
Planning in Merton: what to know before you apply
Merton applies Article 4 directions to HMO conversions in designated wards and controls design within conservation areas such as Wimbledon Village, Wimbledon Common and the John Innes estate at Merton Park. For the borough's interwar semis around Raynes Park and Morden, rear extensions and lofts frequently qualify as permitted development — we confirm before drawing.

What Merton is actually built of
Building form decides what a plan has to show. Attached housing means party walls, shared drainage runs and a narrow back addition to measure carefully; detached stock means the plan has to carry the setting as well as the building. These are measured counts from Ordnance Survey building data, not a description of the borough.

Floor Plans for Merton homes: the package and the process
A floor plan is only as good as the survey behind it. Room dimensions taken from a laser survey rather than an estate agent's sketch, wall thicknesses drawn as they actually are, and structural walls distinguished from partitions — those are what make a plan usable for design work rather than just for marketing.
We issue plans at a stated scale with a scale bar, so they stay measurable when printed or resized, and supply them in formats that work for the next stage: a PDF to share, and CAD where an architect, engineer or kitchen designer needs to draw on top of it.
The plan itself carries the building's history. Chimney breasts, blocked openings, changes in floor level and an outrigger that has been extended more than once all show up in a measured plan, and they are precisely the things a sketched plan leaves out.
What are floor plans used for?
Floor plans serve several distinct purposes in London property: estate agents use them to market a sale or letting alongside photographs, giving buyers and tenants an accurate sense of layout and scale that a floor plan on its own can convey better than photos; solicitors and lenders often require a lease plan showing the demise of a flat within a building, particularly for leasehold sales or re-mortgages; landlords use them to document a property's layout for reference, insurance or portfolio management; and homeowners use them simply to have an accurate record of their existing layout, whether for their own reference or as the first step before considering any building work.
How accurate are laser-measured floor plans?
We measure every floor plan on site using a laser distance meter rather than a tape measure or estimation from photographs, which keeps room dimensions, wall thicknesses and door and window positions accurate to within a few millimetres. This matters more than it might seem: an estate agent's marketing plan that overstates a room's size can mislead a buyer and cause problems at survey stage, while a lease plan used for legal purposes needs to accurately reflect what a leaseholder actually owns. A laser-measured plan also means that if you later want to use it as the existing-layout drawing for a planning application, it is already accurate enough to build proposed drawings on top of, rather than needing to be re-measured.
How much do floor plans cost in London?
A single floor-plan set starts from £450, which covers a laser-measured site visit and scaled, dimensioned drawings of each floor of the property. The exact fee depends on the number of floors, the overall size of the property, and whether you need elevations or a site plan in addition to the floor plans themselves — for example, for a lease plan or as the base for a future planning application. This is a fixed fee agreed upfront, with no hourly billing.
