Richmond (TW9) spans the town centre and the Kew border, layering conservation areas including Kew Green, Richmond Green, Central Richmond and Lawn Crescent across its Georgian and Victorian streets.

The Kew Green conservation area, with the Thames Path running past St Anne's churchyard and Kew Pond, protects 18th-century cottages such as Cambridge Cottages, which carry their own Article 4 direction.

Planning in Richmond (TW9): what to know before you apply

TW9 houses commonly sit inside the Kew Green, Richmond Green or Central Richmond conservation areas, and streets like Cambridge Cottages carry Article 4 directions — plan for front elevations, windows and roofs to need full planning permission rather than permitted development.

Typical Richmond housing stock

Measured Building Survey for Richmond (TW9) homes: the package and the process

Every measured building survey we prepare for an Richmond property is drawn to London Borough of Richmond upon Thames’s validation standards and tuned to the TW9 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 Richmond TW9 — 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 Richmond?+
More often than in most boroughs, yes. Richmond has some of the most extensive Article 4 coverage in London, so permitted development cannot be assumed even for modest works — many conservation areas such as Richmond Green, Teddington and Kew Green require a full application. We confirm the exact designation for your address first and design accordingly rather than relying on permitted development.
My Richmond home is near the river — does flood risk affect my application?+
It can. Much of the borough lies within the Thames flood zone, and the council expects flood-risk considerations to be addressed for works near the river in Twickenham, Richmond and Hampton. We evidence flood-risk and finished-floor-level considerations within the application so the council can validate and approve without repeated revisions.
What does Richmond's Article 4 coverage mean in practice?+
Article 4 directions remove permitted development rights across many of Richmond's conservation areas, so alterations that would be automatic elsewhere — dormers, cladding, some rear works — need a full householder application here. We design context-led drawings that respond to the borough's period townscape and river frontage, which is what carries an application to consent in Richmond.
How long does Richmond Council take to decide?+
Richmond determines most householder applications within the statutory eight-week period once validated, though conservation and riverside cases can attract additional consultation. Because so much turns on design detail here, we prepare submissions to the validation checklist with the elevations and materials the council expects, to avoid drawing queries.
How much do planning drawings cost in Richmond?+
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 Richmond approves. Conservation and flood-zone cases require more evidence than a standard extension, so we quote once we understand your address and scheme rather than by the hour.
