Croydon is one of London's largest boroughs by population, running from the dense Victorian and Edwardian terraces of Thornton Heath, South Norwood and Addiscombe up to the generous interwar semi-detached and detached houses of Purley, Sanderstead and Coulsdon on the southern hills, with town-centre flats and larger homes in between. That range means the right project varies widely — a compact side-return in Addiscombe is a different exercise from a substantial double-storey extension on a large Purley plot — and the sloping sites across the southern hills further shape how an extension or lower-ground scheme is designed.

The suburban semis and detached homes toward Purley and Sanderstead often retain fuller permitted development rights than inner-London terraces, so larger rear and double-storey extensions can qualify, with the limit usually design and amenity policy rather than space. That said, the conservation areas of Addiscombe, South Norwood, Park Hill, Upper Norwood, Waddon and Sanderstead tighten design control where they apply, and Croydon's HMO Article 4 directions remove permitted development for change of use to an HMO (C3 to C4) in designated wards. We take a validation-first approach, checking the permitted development limits for your semi-detached or detached home — and confirming eligibility with a Lawful Development Certificate where it qualifies — before drawing.

We prepare Croydon planning drawings that use the available plot fully while respecting conservation control, producing the same council-accepted drawings an architect would across Croydon, Purley, Thornton Heath, Norbury and Coulsdon — usually at around 30% less. The fee is fixed and agreed up front, drawings typically turn around in about seven days, and we redraw free until Croydon approves. Most householder applications are determined within the statutory eight-week period once validated, so for a large borough spanning terraces to suburban plots a complete, correctly scaled submission to the council's checklist is the best way to avoid a validation query.

Planning in Croydon: what to know before you apply

Croydon applies Article 4 directions to HMO conversions in designated wards and controls office-to-residential change of use in parts of the town centre, alongside conservation-area design control in Addiscombe, South Norwood and Upper Norwood. The suburban semis and detached homes toward Purley and Sanderstead often retain fuller permitted development rights than inner-London terraces — we confirm before drawing.

Floor Plans for Croydon homes: the package and the process

Every floor plans we prepare for a Croydon property is drawn to Croydon Council’s validation standards and tuned to the local 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 Croydon — 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 an extension in Croydon?+
It depends where in the borough you are. The interwar semis and detached homes of Purley, Sanderstead and Coulsdon often keep fuller permitted development rights than inner-London terraces, so larger rear and single-storey extensions can qualify. Conservation areas such as Addiscombe and South Norwood, and HMO Article 4 wards, restrict this. We check your address first and can confirm permitted development with a Lawful Development Certificate.
Can I build a larger extension on a Purley or Sanderstead plot?+
Often, yes. Croydon's generous suburban plots make substantial rear and double-storey extensions viable where a tight terrace could not accommodate them. The limit is usually design and amenity policy rather than space. We design to use the plot fully within permitted-development allowances or a well-evidenced full application, checking the limits for detached and semi-detached homes first.
What do Croydon's HMO Article 4 directions mean for me?+
In designated wards, an Article 4 direction removes permitted development for change of use to an HMO (C3 to C4), so a conversion to a house in multiple occupation needs a full application there. It doesn't affect a standard family extension, but if you are considering an HMO we confirm whether the direction covers your address and use before advising on a route.
How long does Croydon Council take to decide?+
Croydon determines most householder applications within the statutory eight-week period once validated. As a large borough spanning terraces to suburban plots, a complete, correctly scaled submission is the best way to avoid a validation query — we prepare Croydon drawings to the council's checklist to keep the application on track.
How much do planning drawings cost in Croydon?+
We quote a fixed fee upfront, typically around 30% below an architect's charge for the same council-accepted drawings, with free redraws until Croydon approves. Because plots here allow larger schemes, the fee tracks complexity — a single-storey rear differs from a double-storey — and we confirm it once we understand your plans.
