Chipping Barnet (N20) is a historic medieval market town strung along the Great North Road, granted its charter in 1199 and sitting on the high ridge of High Barnet. Its housing tells that story in layers: Victorian and Edwardian terraces and villas near the old High Street give way to interwar semi-detached and detached houses on the surrounding hillside roads, so most householder projects here are extensions or lofts that have to sit comfortably within a genuinely mixed streetscape.

There is no conservation area covering the N20 part of Chipping Barnet — that is a genuine, verified fact, not an omission. Its planning character is instead shaped by the mix of Victorian, Edwardian and interwar housing and by the London Borough of Barnet's householder design expectations, which lean on keeping original building lines, bay details, materials and roof forms intact. We treat that period character, rather than a conservation designation, as the reference point when we design an extension.

Demand for rear extensions, side infills and loft conversions runs steadily across roads like Oakleigh Park North, Langton Avenue and Buckingham Avenue, where generous interwar plots sit alongside tighter terraced runs closer to the town centre. We check each property's permitted-development position against Barnet's borough-wide controls first, then prepare drawings that either stay within permitted development or are ready to validate as a full householder application.

Planning in Chipping Barnet (N20): what to know before you apply

Because Chipping Barnet mixes Victorian, Edwardian and interwar housing, Barnet assess extensions against the prevailing character of the individual street, so matching original brick, render, bay detailing and roof form matters as much as the numbers. There is no conservation area and no local Article 4 direction in the N20 part of the district, so many houses retain permitted development rights for rear and loft work — but varied plot sizes, shared building lines and the sloping ridge topography mean depth, height and neighbour impact are the points a householder application is judged on.

This layering of periods is what drives the steady flow of rear-extension, side-infill and loft-conversion work across the district.

Floor Plans for Chipping Barnet (N20) homes: the package and the process

Every floor plans we prepare for an Chipping Barnet property is drawn to London Borough of Barnet’s validation standards and tuned to the N20 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 Chipping Barnet N20 — 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 to extend a house in Chipping Barnet?+
Not always. Many Chipping Barnet houses retain permitted development rights, so a modest single-storey rear extension or a rear loft conversion can often proceed without a full planning application. Because the district mixes tighter terraces with more generous interwar plots on sloping ground, we check your property's size limits, building lines and levels against Barnet's controls first, and prepare a full householder application where the project goes beyond permitted development.
Is Chipping Barnet in a conservation area?+
No. There is no conservation area covering the N20 part of Chipping Barnet. Its planning character is shaped instead by the layered mix of Victorian, Edwardian and interwar housing and Barnet's householder design expectations, which favour keeping original building lines, bay details, materials and roof forms intact when you extend.
How much do planning and building-regulation drawings cost for a Chipping Barnet extension?+
We work to fixed fees agreed before we start, with a typical turnaround of around seven days for a standard rear extension or loft on a Chipping Barnet house. As a chartered architectural technologist practice we produce the same council-accepted planning and building-regulation drawings as an architect, usually for a lower fee, and include free redraws until your application is approved.
