Bickley BR2 is one of Bromley's most spacious suburbs, a landscape of detached Victorian and Edwardian villas around Bickley Park Road where deep plots make rear extensions, side infills and garden rooms the natural way to add space.

Much of the area lies within the Bickley Conservation Area, which removes several permitted development rights, so we confirm whether a property sits inside that boundary before recommending permitted development over a full householder application to Bromley.

Planning in Bickley (BR2): what to know before you apply

Bickley properties inside the conservation area typically need full householder applications to Bromley, with generous plots supporting well-set-back rear and side extensions. Homes outside the boundary may retain permitted development for some works. We check the exact designation and plot before advising.

Typical Bickley housing stock

Spacious detached late-Victorian and Edwardian villas set on generous plots around Bickley Park Road and Page Heath Lane, many with deep gardens that suit substantial rear and side extensions and garden rooms.

Measured Building Survey for Bickley (BR2) homes: the package and the process

Every measured building survey we prepare for an Bickley property is drawn to London Borough of Bromley’s validation standards and tuned to the BR2 constraints above. Here is what the drawing package covers and how the process runs from first survey to approval.

Every accurate drawing starts with an accurate survey. Before any proposed extension, loft conversion or alteration can be designed, we need to know exactly what already exists — the true dimensions of each room, the position and size of every door and window, floor-to-ceiling heights, wall thicknesses, roof pitches and the exact shape of the plot. A measured building survey captures all of this on site using a laser distance meter, recording existing plans, elevations and sections to millimetre accuracy, rather than relying on old estate agent floor plans, a previous owner's drawings, or rough on-site guesswork.

This matters more than it might seem. A design drawn on top of an inaccurate existing survey can look correct on paper and then not actually fit once a builder is on site — a wall that is 200mm out of position, a ceiling height that is lower than assumed, or a roof pitch that does not match reality can all force a costly redesign mid-build. A fresh, laser-measured survey de-risks that from the outset: the proposed extension, loft conversion or internal alteration is designed against the real dimensions of your home, not an approximation, so what is drawn is what can actually be built.

Why does a planning or building regulations application need a measured survey?

A planning or building regulations application needs to show the existing building accurately alongside the proposed changes, so the council or Building Control can judge the impact of the work against what is actually there. Existing plans, elevations and sections drawn from an accurate measured survey give the borough confidence that the proposal has been designed against real dimensions, and give your builder a reliable set of drawings to price and build from — an application based on inaccurate or assumed dimensions risks queries, delays, or a design that does not translate cleanly on site.

What does a measured building survey capture?

The survey records everything needed to produce accurate existing drawings: internal room dimensions and floor-to-ceiling heights on every level, the position, width and height of every door and window, wall thicknesses, staircase dimensions and headroom, roof shape and pitch, chimney breasts and structural features, and the external footprint and boundary relationship of the property. Where relevant to the project, we also record ground levels, existing drainage runs and neighbouring boundary conditions.

This is captured with a laser distance meter rather than a tape measure, which keeps the survey accurate to within a few millimetres across a whole property and removes the cumulative measuring error that can creep into a hand-measured survey of a larger or more complex building.

FAQ

Measured Building Survey in Bickley BR2 — FAQs

How much does a measured building survey cost?+
A measured building survey starts from £450, or is included as the first stage of a planning, building regulations or architectural drawing package, depending on the size and complexity of the property.
How long does a measured survey take?+
The site visit itself typically takes a few hours depending on the size of the property, with existing drawings produced from the survey data shortly afterwards as the basis for the next stage of your project.
Is a measured survey the same as a floor plan?+
A measured survey is the site data-capture process; floor plans are one of the outputs drawn from it. The same survey can also produce elevations, sections and the existing-layout base drawing for a planning application.
Do I need a measured survey if I am only doing internal work?+
Usually yes if you are removing or altering walls, since accurate existing dimensions and structural features are needed to design and calculate the changes safely, even where no planning application is required.
Can the survey be used for more than one purpose?+
Yes — a single measured survey typically underpins floor plans, planning drawings, building regulations drawings and structural calculations for the same project, so it only needs to be carried out once.
Do I need planning permission for an extension in Bromley?+
Bromley has no borough-wide Article 4 direction affecting typical householder permitted development, so its detached and semi-detached homes often keep fuller rights than inner-London terraces — larger rear and single-storey extensions can qualify. The binding constraints are green-belt policy on outer properties and conservation control in Chislehurst, Keston and Bromley Town. We check both and can confirm permitted development with a Lawful Development Certificate.
Can I build a bigger extension because Bromley plots are larger?+
Often, yes. Bromley's generous interwar plots make substantial rear and double-storey extensions viable where an inner-London terrace could not accommodate them. The limit is usually policy rather than space — green belt restricts scale on outer properties, and conservation areas control design. We design to use the plot fully within those limits, checking permitted-development allowances for detached homes first.
How does green-belt designation affect my Bromley project?+
On green-belt properties toward Orpington, Chislehurst and the borough's edges, extensions are assessed against strict limits on disproportionate additions to the original dwelling. It does not rule out an extension, but scale and siting matter and the case must be evidenced carefully. We confirm whether your property is green belt and design a scheme that stays within policy.
How long does Bromley Council take to decide?+
Bromley determines most householder applications within the statutory eight-week period once validated. As London's largest borough by area, its casework spans suburban semis to green-belt properties, so a complete, correctly scaled submission is the best way to avoid a validation query and keep to that timescale.
How much do planning drawings cost in Bromley?+
We quote a fixed fee upfront, typically around 30% below an architect's charge for the same council-accepted drawings, with free redraws until Bromley approves. Because plots here allow larger schemes, the fee tracks the project's complexity — a single-storey rear differs from a double-storey or a green-belt case — and we confirm it once we understand your plans.
