West Wickham (BR4) is a classic interwar railway suburb: once Kent farmland, it was laid out for London commuters after the station opened, and its character today is overwhelmingly 1920s–1930s semi-detached and detached houses on generous, planned plots. Almost every householder project here is a rear extension, side infill or loft on one of those suburban houses, so drawings need to sit comfortably within wide, evenly spaced streets.

There is no conservation area covering West Wickham — that is a genuine, verified fact, not an omission. Its planning character is instead shaped by the consistency of the interwar suburb: regular building lines, front-garden setbacks and the spacing between houses, all read against Bromley's householder design expectations. We treat that suburban grain, rather than a conservation designation, as the reference point when we design an extension.

Because the plots are deep and the layout is so regular, demand for rear extensions and loft conversions is steady along roads like Wickham Chase, Pickhurst Rise and Red Lodge Road. We check each property's permitted-development position against Bromley's borough-wide controls first, then prepare drawings that either stay within permitted development or are ready to validate as a full householder application.

Planning in West Wickham (BR4): what to know before you apply

Bromley assesses West Wickham extensions against the settled interwar suburban pattern, so matching original brick, render and roof form and respecting the gaps between houses matters more than on a mixed-typology road. There is no conservation area and no local Article 4 direction, so many houses retain permitted development rights for rear and loft work — but two-storey side additions, roof changes and neighbour amenity are the points a householder application is judged on.

Typical West Wickham housing stock

Predominantly 1920s–1930s semi-detached and detached houses on wide, planned suburban roads, with some later postwar infill. The generous plots and deep rear gardens that came with garden-suburb-influenced planning are exactly what make rear extensions and loft conversions such common projects here.

Floor Plans for West Wickham (BR4) 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.

FAQ

Floor Plans in West Wickham BR4 — 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 to extend a house in West Wickham?+
Not always. Many West Wickham houses retain permitted development rights, so a single-storey rear extension or a rear loft conversion can often proceed without a full planning application. Because the interwar plots and building lines are regular, we check your property's limits against Bromley's controls first and prepare a full householder application where the project — such as a two-storey side extension — goes beyond permitted development.
Is West Wickham in a conservation area?+
No. There is no conservation area covering West Wickham. Its planning character is shaped instead by the consistency of the interwar railway suburb — the regular building lines, front-garden setbacks and gaps between houses — and by Bromley's householder design expectations, which favour keeping that spacious suburban grain when you extend.
How much do planning and building-regulation drawings cost for a West Wickham extension?+
We work to fixed fees agreed before we start, with a typical turnaround of around seven days for a standard rear extension or loft on a West Wickham house. As a chartered architectural technologist practice we produce the same council-accepted planning and building-regulation drawings as an architect, usually for a lower fee, and include free redraws until your application is approved.
How long does Bromley Council take to decide?+
Bromley determines most householder applications within the statutory eight-week period once validated. As London's largest borough by area, its casework spans suburban semis to green-belt properties, so a complete, correctly scaled submission is the best way to avoid a validation query and keep to that timescale.
