Hanwell (W7) keeps a genuine village feel around its green, with historic buildings on spacious, tree-filled plots giving way to consistent Victorian and Edwardian terraces on the surrounding streets. Rear and loft projects follow the familiar Ealing terrace pattern on most roads, but the conservation-area picture is more layered than it first looks.

The Hanwell Village Green conservation area protects the older core, while the St Mark's Church and Canal area runs along the Brent and the Grand Union Canal to the south. We establish which context a Hanwell property sits in — ordinary terrace, protected village core or canal-side setting — before drawing to the borough's guidance.

Planning in Hanwell (W7): what to know before you apply

W7 carries no householder Article 4 direction affecting typical work, so many Hanwell houses retain permitted development rights for rear and loft projects — but the Hanwell Village Green, St Mark's Church and Canal, and Hanwell Cemeteries conservation areas are the exceptions where character, plots and trees are actively protected. London Borough of Ealing does not publish an Article 4 schedule to the national open-data register, so we verify the current position with the council before advising.

Typical Hanwell housing stock

Late-Victorian and Edwardian terraces and semi-detached houses across the district, older historic buildings on spacious plots around the village green, and larger houses in the Golden Manor enclave.

Floor Plans for Hanwell (W7) 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 £275, 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.

FAQ

Floor Plans in Hanwell W7 — FAQs

How much do floor plans cost in London?+
Floor plans start from £275 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 rear extension in Ealing?+
Many Ealing semis and terraces keep permitted development rights for a single-storey rear extension, so a full application isn't always needed. In a conservation area such as Bedford Park or Pitshanger, dormers and other roof enlargements, side extensions, rear extensions over one storey and cladding are not permitted development. The borough-wide Article 4 direction on HMO conversions is a separate change-of-use control. We check your address against the designations first and, where it qualifies, confirm permitted development with a Lawful Development Certificate.
What extra control applies in Bedford Park?+
Bedford Park is one of West London's most tightly controlled conservation areas, with detailed control over materials, rooflines, windows and front elevations. In a conservation area dormers and other roof enlargements, side extensions, rear extensions over one storey and cladding are not permitted development, so we design to the area's Arts-and-Crafts character and prepare a full householder application with the elevations and materials the council expects.
How long does Ealing Council take to decide a householder application?+
Ealing has eight weeks from the day after it receives a valid application, unless a longer period is agreed in writing. We follow the council's validation checklist: correctly scaled existing and proposed plans, elevations and a location plan.
Can you help with a loft conversion on a 1930s Ealing semi?+
Yes. Ealing's Metro-land semis in Perivale, Greenford and Northolt suit hip-to-gable and dormer loft conversions, which frequently qualify as permitted development on semi-detached homes within the volume limits. We confirm eligibility against those limits and any Article 4 or conservation constraint, then produce the planning and building-regulations drawings.
How much do planning drawings cost in Ealing?+
We work to a fixed fee agreed before we start, taken from our published price list, with free redraws until Ealing grants approval. The exact figure depends on the project — a single-storey rear extension differs from a double-storey or a loft — so we quote once we understand your scheme rather than on an open-ended hourly basis.
