HA2 covers North Harrow, Rayners Lane, West Harrow and Roxeth — largely a Metro-land suburb of 1920s and 1930s semis where rear extensions, loft conversions and side infills are the everyday projects. The uniform inter-war house type means Harrow's design expectations for extensions are well understood across most of the district.

Two genuine conservation areas sit inside HA2: Roxeth Hill (designated 1969), a historic village pocket at the foot of Harrow Hill, and Rayners Lane (designated 2002), which protects the Charles Holden station and the Art Deco parades on Alexandra Avenue. We confirm which side of those boundaries a property falls on before advising.

Planning in North Harrow and Rayners Lane (HA2): what to know before you apply

Most inter-war semis in HA2 retain permitted-development rights for rear and loft work, so many projects avoid a full application. The exceptions are the Roxeth Hill and Rayners Lane conservation areas, where roofline, front-elevation and material changes face tighter control and a householder application is usually needed.

Typical North Harrow and Rayners Lane housing stock

Floor Plans for North Harrow and Rayners Lane (HA2) homes: the package and the process

Every floor plans we prepare for an North Harrow and Rayners Lane property is drawn to London Borough of Harrow’s validation standards and tuned to the HA2 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.

Not every project needs a full planning drawing set. If you are selling or letting a property, drawing up a lease, recording a layout before a refurbishment, or simply want an accurate plan of your home, what you need is a floor plan — a scaled, dimensioned drawing of each level, measured directly from the property rather than estimated from an old plan or an estate agent's rough sketch. DrawingsDirect produces floor plans from a laser-measured site visit, so room sizes, wall thicknesses and door and window positions are accurate, not approximate.

Floor plans are commonly used for estate agency marketing and Rightmove or Zoopla listings, for lease plans required by a mortgage lender or solicitor, for landlords documenting a rental property's layout, or as a straightforward existing-layout record before any building work is decided. They are lighter than a full architectural or planning drawing set — there is no design work, no application, and no borough-specific requirements to satisfy — so turnaround is fast and the fee is correspondingly lower. If you later decide to extend, convert a loft or apply for planning permission, the same laser survey can usually be reused as the base for those drawings rather than re-measuring the property from scratch.

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.

FAQ

Floor Plans in North Harrow and Rayners Lane HA2 — FAQs

How much do floor plans cost in London?+
Floor plans start from £450 for a laser-measured, scaled drawing of each floor, with the exact fee depending on the size of the property and the number of floors involved.
How long does it take to get floor plans?+
Most floor plans are ready within a few days of the site survey, considerably faster than a full planning drawing set, since there is no design or application work involved.
Can floor plans be used for a lease or mortgage application?+
Yes — laser-measured floor plans are commonly used as lease plans and for mortgage or re-mortgage purposes; let us know at the outset if you need a specific format or additional detail such as room areas.
Can I reuse my floor plans if I later want to extend or convert my loft?+
Yes — the laser survey behind your floor plans can usually be reused as the existing-layout base drawing for a future planning or building regulations application, saving you from a second site visit.
Do you provide floor plans for estate agents?+
Yes, floor plans are commonly instructed directly by homeowners or via their estate agent ahead of a sale or letting, drawn to scale and ready to use alongside marketing photography.
Do I need planning permission for a loft conversion in Harrow?+
Harrow's Metro-land semis and detached houses in Rayners Lane, Kenton and Stanmore suit hip-to-gable and dormer lofts, which frequently qualify as permitted development within the volume limits. The exceptions are the conservation areas — Harrow on the Hill and Pinner's historic core — and the Article 4 wards. We check your address and can confirm permitted development with a Lawful Development Certificate.
What does Harrow expect for a rear extension on a 1930s semi?+
The council pays close attention to preserving the rhythm and building line of its interwar suburban streets, so extensions are expected to respect the established line and roof form. Many single-storey rear extensions still fall within permitted development; where a full application is needed, we design to the borough's residential guidance so it validates and approves without repeated revisions.
Can I extend a home in Harrow on the Hill or Pinner?+
Yes, but these historic conservation areas carry a heritage setting and long views the council protects closely, so permitted development is often restricted and a full, context-led application is required. We design to the character of the area — materials, proportions and rooflines — and evidence the heritage considerations so the submission stands up.
How long does Harrow Council take to decide?+
Harrow determines most householder applications within the statutory eight-week period once validated. The commonest delay is a validation query, so we prepare Harrow submissions to the council's checklist with correctly scaled existing and proposed drawings and a location plan to keep the application on track.
How much do planning drawings cost in Harrow?+
We work to a fixed fee agreed upfront, usually around 30% below an architect's charge for the same council-accepted drawings, with free redraws until Harrow approves. The figure depends on the scheme — a dormer loft differs from a double-storey extension — so we confirm it once we understand your project rather than billing by the hour.
