Streatham (SW16) is a long, mixed Lambeth neighbourhood that runs from the terraces off the High Road out to the interwar semis of Streatham Vale. The most consistent control is the Streatham Common conservation area, which governs roof form, materials and frontages for houses around the Common — a very different context from the standard terraces further north where side-return and loft projects follow the usual pattern.

Because the housing grain shifts from terrace to semi across the district, the right extension approach genuinely varies street to street. We establish where a Streatham property sits relative to the Common conservation area and the High Road frontage, then prepare the drawings to Lambeth's residential design and validation standards.

Planning in Streatham (SW16): what to know before you apply

SW16 has no householder Article 4 direction, so many Streatham houses retain permitted development rights — but the Streatham Common conservation area is the exception, and the interwar semis toward Streatham Vale carry different design expectations from the Victorian terraces nearer the High Road.

Typical Streatham housing stock

Victorian and Edwardian terraces on the streets off Streatham High Road, interwar semi-detached houses toward Streatham Vale and Norbury, and mansion blocks along the High Road and around the Common.

Floor Plans for Streatham (SW16) homes: the package and the process

Every floor plans we prepare for an Streatham property is drawn to London Borough of Lambeth’s validation standards and tuned to the SW16 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 Streatham SW16 — 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 a side-return extension in Lambeth?+
On many of Lambeth's Victorian and Edwardian terraces in Brixton, Clapham and Streatham, a single-storey side-return or rear extension can fall within permitted development, so a full application isn't always required. Conservation areas such as Clapham Common and Brixton Water Lane can restrict this. We check your street's designation first and can confirm permitted development with a Lawful Development Certificate.
My Lambeth home is a converted flat — does that change things?+
It often does. Many Lambeth houses are converted flats, so ownership, lease and party-wall considerations can matter as much as the planning route, and the freeholder's agreement is usually needed alongside planning. We resolve the ownership and shared-structure context before drawing so the scheme is deliverable, not just consentable.
What does Lambeth's HMO Article 4 direction affect?+
Lambeth applies an Article 4 direction removing permitted development rights for HMO conversions (C3 to C4) in designated parts of the borough, so a change of use to a house in multiple occupation needs a full application there. It doesn't affect a standard family extension, but we confirm whether it applies to your address and use before advising on a route.
How long does Lambeth Council take to decide?+
Lambeth determines most householder applications within the statutory eight-week period once validated. The terraced grids around Clapham and Brixton are party-wall-sensitive with well-established design expectations, so the commonest delay is a drawing query — we prepare submissions to the borough's residential extension guidance to keep them moving.
How much do planning drawings cost in Lambeth?+
We agree a fixed fee before starting, usually around 30% below an architect's fee for the same council-accepted drawings, with free redraws until Lambeth approves. A side-return, a loft and a flat-conversion scheme differ in complexity, so we quote once we understand your street and project rather than charging by the hour.
