Merton Park in SW19 is the John Innes estate, an early and carefully planned Arts-and-Crafts garden suburb within the London Borough of Merton. Its detached and semi-detached houses sit behind protected verges and hedges, so the typical projects are sensitively designed rear extensions, loft conversions and internal reworking rather than prominent frontage changes.

Because most of the estate lies within the John Innes conservation area, control over materials, roof forms, boundaries and even planting is unusually strong, and permitted-development rights are curtailed. We design in keeping with the estate's Arts-and-Crafts character and prepare the detailed, well-justified applications Merton's conservation officers require.

Planning in Merton Park (SW19): what to know before you apply

Merton Park sits largely within the John Innes conservation area, so while there is no separate published householder Article 4 direction we rely on, conservation status significantly reduces permitted-development rights and requires planning permission for most external changes. Protected verges, hedges and TPO trees further constrain extension footprints and boundary alterations.

Typical Merton Park housing stock

Merton Park is the John Innes garden suburb, an early planned Arts-and-Crafts estate of detached and semi-detached houses set behind protected verges, hedges and mature planting. The generous but tightly controlled plots mean sensitively designed rear extensions and loft conversions, rather than bold frontage changes, are the typical projects.

Floor Plans for Merton Park (SW19) homes: the package and the process

Every floor plans we prepare for an Merton Park property is drawn to London Borough of Merton’s validation standards and tuned to the SW19 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 Merton Park SW19 — 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 Merton?+
The interwar semis of Raynes Park and Morden often keep permitted development rights for rear extensions and lofts, so a full application isn't always needed. Conservation areas such as Wimbledon Village, Wimbledon Common and the John Innes estate at Merton Park restrict this. We check your street's designation first and can confirm permitted development with a Lawful Development Certificate.
What is special about building at the John Innes estate in Merton Park?+
The John Innes estate is a planned Arts-and-Crafts conservation area with a distinctive character the council protects closely — materials, proportions and rooflines are all controlled. Permitted development is often restricted there, so we design to the estate's character and prepare a full, context-led application, which is the reliable route to approval.
What do Merton's HMO Article 4 directions affect?+
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.
How long does Merton Council take to decide?+
Merton determines most householder applications within the statutory eight-week period once validated; Wimbledon and Merton Park conservation cases can involve additional consultation. We prepare submissions to the council's validation checklist to avoid the drawing queries that cause most delays.
How much do planning drawings cost in Merton?+
We agree a fixed fee before starting, typically around 30% below an architect's fee for the same council-accepted drawings, with free redraws until Merton approves. A suburban Raynes Park extension and a Wimbledon Village or Merton Park application differ in the evidence required, so we quote once we understand your address and project rather than by the hour.
