Floor Plans in Islington N1
Fixed-fee, MCIAT-chartered floor plans for Islington (N1) homeowners — London Borough of Islington validation and local constraints handled from the start.
Islington (N1) is one of London's most tightly protected Georgian districts — the terraces and squares around Upper Street, Liverpool Road and Duncan Terrace are largely early-nineteenth-century, and a large share of them are either listed or sit inside a conservation area. That combination makes N1 a district where the drawings, not the ambition, decide whether a scheme is consentable.
The Regent's Canal conservation area runs through N1 and controls the canal-side setting, which means rear elevations and roof alterations visible from the towpath are assessed on their contribution to that view rather than in isolation. Combined with the shallow rear gardens typical of the Georgian plots, most successful N1 projects are loft and lower-ground work rather than deep rear extensions. We check the listing register and the conservation-area boundary for an N1 address before drawing anything to Islington's guidance.
Planning in Islington (N1): what to know before you apply
N1 had no householder Article 4 direction intersect our sample of the district, but that offers little practical freedom here: the density of listed Georgian terraces means listed building consent, not permitted development, is the governing question on most Islington streets, and the Regent's Canal conservation area controls the canal-side setting including rear elevations seen from the towpath. Shallow Georgian rear gardens are the other hard limit on extension depth.
Typical Islington housing stock

Floor Plans for Islington (N1) 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.
