Measured Building Survey in Bexley Village DA5

Fixed-fee, MCIAT-chartered measured building survey for Bexley Village (DA5) homeowners — London Borough of Bexley validation and local constraints handled from the start.

Bexley Village (DA5) sits on the River Cray at the south-eastern edge of the borough, where the historic High Street winds down past cottages and shops to the green and St John's Church. Rear and side extensions on the Victorian and Edwardian houses ringing the old core are the most common projects here, and the village's semi-rural setting on the edge of the Metropolitan Green Belt shapes how the council reads them.

The Old Bexley Conservation Area, first designated in 1971 and extended in 1987, covers the winding High Street, the green and the riverside around the old ford, protecting 18 listed buildings and the prevailing local brick. Where a DA5 property sits relative to that boundary decides whether roofline, window and front-elevation changes are permitted development or need consent.

Housing stock: The conservation-area core is a tight grain of 18th- and 19th-century brick cottages, listed timber-framed houses and Victorian shopfronts along the winding High Street, giving way to Edwardian villas and inter-war semis on the rising ground toward Bexley station and Parkhill Road.
Article 4: The Old Bexley Conservation Area is covered by an Article 4(2) Direction that removes permitted-development rights for alterations to front elevations, roofs, chimneys, windows and highway-facing boundary walls, so like-for-like changes there still require a householder application.

Planning in Bexley Village (DA5): what to know before you apply

Inside the Old Bexley Conservation Area the Article 4(2) Direction means front-elevation, roof, window and boundary changes that would be permitted development elsewhere need a full householder application, and the 18 listed buildings additionally require listed-building consent. Beyond the boundary, on the Edwardian and inter-war streets toward the station, many rear and loft projects still fall within permitted development, so we check the boundary and the Green Belt edge before advising a route.

Measured Building Survey for Bexley Village (DA5) homes: the package and the process

Every measured building survey we prepare for an Bexley Village property is drawn to London Borough of Bexley’s validation standards and tuned to the DA5 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 Bexley Village DA5 — 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 Bexley?+

Bexley has no borough-wide Article 4 direction affecting typical householder permitted development, so its semi-detached homes often keep fuller rights than inner-London terraces — larger rear and single-storey extensions can qualify. Conservation areas such as Old Bexley Village and Danson Park, and riverside flood-zone constraints toward Erith, restrict this. We check your address first and can confirm permitted development with a Lawful Development Certificate.

Can I build a bigger extension because Bexley plots are larger?+

Often, yes. The generous interwar plots across Bexleyheath, Sidcup and Welling make substantial rear and double-storey extensions viable where a tight terrace could not. 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.

What extra control applies in Old Bexley Village or around Danson Park?+

These conservation areas carry design control over materials, rooflines and front elevations, and the Upton area of Bexleyheath includes the setting of William Morris's Red House. Permitted development is often restricted there, so we design to the area's character and prepare a full, context-led application where a standard permitted-development route doesn't apply.

How long does Bexley Council take to decide?+

Bexley determines most householder applications within the statutory eight-week period once validated; conservation cases can involve additional consultation. A complete, correctly scaled submission is the best way to avoid a validation query — we prepare Bexley drawings to the council's checklist to keep the application on track.

How much do planning drawings cost in Bexley?+

We quote a fixed fee upfront, typically around 30% below an architect's charge for the same council-accepted drawings, with free redraws until Bexley 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.
