Planning Permission in Barnes SW13
Fixed-fee, MCIAT-chartered planning permission for Barnes (SW13) homeowners — London Borough of Richmond upon Thames validation and local constraints handled from the start.
Barnes (SW13) is an unusually intact riverside village in Richmond, and it is heavily conservation-controlled: four conservation areas — Barnes Common, Barnes Green, Castelnau and Madrid Road — cover most of the housing. Whether a property sits inside one of those boundaries, and often it does, is the single biggest factor in how an extension, loft or elevation change is designed and assessed.
The Thames wraps the neighbourhood on two sides, so riverside houses along Lonsdale Road and the Terrace also carry flood-zone considerations, and Barnes Common is protected metropolitan open land. We map a Barnes property against the conservation, flood-zone and open-land boundaries first, then design the drawings to Richmond's residential and conservation guidance so the application is validated without a query.
Planning in Barnes (SW13): what to know before you apply
SW13 has no householder Article 4 direction, but its four conservation areas mean permitted development cannot be assumed across most of Barnes, and riverside properties along Lonsdale Road sit within the Thames flood zone — both are checked before we recommend a route.
Typical Barnes housing stock
Victorian and Edwardian terraces and cottages around Barnes Green and the village, the grand Italianate semi-detached villas along Castelnau toward Hammersmith Bridge, and riverside houses fronting the Thames on Lonsdale Road.

Planning Permission for Barnes (SW13) homes: the package and the process
A householder application is refused validation far more often than it is refused permission, and almost always for the same reasons: a location plan at the wrong scale, no red line around the application site, a missing ownership certificate, or elevations that do not show every face of the building affected. We prepare the full submission set — location plan, block plan, existing and proposed floor plans, elevations and sections — so the case officer receives a complete case on day one.
Once the application is live we stay on it. Officers routinely come back with questions about materials, boundary treatment or a dimension they cannot read off the drawings, and a fast, drawn answer is usually the difference between a decision inside the statutory period and a request to withdraw and resubmit.
Which route applies is decided by the building before it is decided by policy. A house that has never been extended usually has allowances left to use; a flat, a listed building or a home in a conservation area often has none, and the same drawing set then has to make a design case rather than a compliance one.
Do I need planning permission for an extension in London?
Many single-storey rear extensions, loft conversions and outbuildings fall under permitted development rights and do not need a full planning application — but London's dense housing stock, conservation areas and Article 4 directions frequently withdraw those rights. Before you pay for a full application, we check your property against the current permitted development thresholds and your borough's local constraints.
Where permitted development applies, we recommend a Lawful Development Certificate instead of full planning — it is faster, cheaper and gives you a legal document confirming the work was lawful. Where a full application is genuinely required, we prepare it properly the first time.
Permitted development vs a full planning application
Permitted development lets you build within defined volumetric limits without committee review. A full householder application is assessed against the borough's local plan for scale, daylight, neighbour impact and design. We advise which route your project qualifies for and why.
Article 4 directions and conservation areas
If your home sits in a conservation area or under an Article 4 direction, permitted development rights are often removed — meaning even modest changes need consent. Each borough page lists the local directions and conservation areas we routinely design around.
How do you apply for planning permission through the London Planning Portal?
We manage the full lifecycle of your submission — survey, drawings, supporting documents and officer liaison — so you never have to decode a validation checklist yourself.
Phase 1 — existing and proposed site surveys
A laser-measured survey captures your property exactly, so existing and proposed drawings match reality millimetre for millimetre.
Phase 2 — technical drawing package
Site location plan, block plan, floor plans, elevations and sections drawn to your borough's scale and formatting requirements, with a design and access statement where needed.
Phase 3 — liaison with the planning officer
We answer the council's queries, negotiate amendments, and redraw free until the decision lands.
How long does planning permission take, and what does it cost?
Drawings are typically ready within 7 days of survey. Your council then has a statutory 8 weeks to decide a householder application. Our drawing fees are fixed and quoted upfront — the table below shows typical packages.
| Package | Production window | Compliance layer | Typical fee |
|---|---|---|---|
| Permitted Development pack | 7–10 working days | Lawful Development Certificate submission | £950–£1,450 |
