Floor Plans in Sidcup DA14
Fixed-fee, MCIAT-chartered floor plans for Sidcup (DA14) homeowners — London Borough of Bexley validation and local constraints handled from the start.
Sidcup's DA14 streets run from the 1930s semis of the Cray valley to the historic core of Foots Cray village, and most of our work here is rear kitchen extensions and loft conversions that add space to those bay-fronted family homes without losing garden depth.
If your home sits inside the Foots Cray Conservation Area the permitted-development shortcuts narrow, so we always confirm the boundary line first and then advise whether a project runs under permitted development or needs a full householder planning application to Bexley.
Planning in Sidcup (DA14): what to know before you apply
Most DA14 extensions and lofts outside the conservation area proceed under permitted development or a lawful development certificate. Inside the Foots Cray Conservation Area, or where a home backs onto Foots Cray Meadows or carries protected trees, a full householder planning application to Bexley is the safer route. We check the boundary and tree constraints before recommending either path.
Typical Sidcup housing stock
DA14 is dominated by 1930s bay-fronted semis and terraces along the Cray valley, wrapped around the older historic core of Foots Cray village where Victorian and Georgian buildings survive on the High Street. Larger detached and inter-war housing sits on the roads backing onto Foots Cray Meadows.

Floor Plans for Sidcup (DA14) 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.
