SW13 primarily covers Barnes in Richmond upon Thames.
Decisions for SW13 are made by Richmond Council. Standard Permitted Development rules apply for most rear extensions and loft conversions on terraced and semi-detached houses, unless the property is in a conservation area, is listed, or sits under an Article 4 Direction. Article 4 in Richmond upon Thames: No.
Building regs from £950. We do not charge hourly. Free site survey across all SW13 addresses.
From first call to planning decision: typically 12–14 weeks. Site survey week 1, design weeks 2–3, validation 1–2 weeks, statutory 8-week determination. Richmond Council timelines align with the national norm.
Barnes in SW13 is characterised by the housing stock of Richmond upon Thames — broadly georgian in richmond green and twickenham.

Every SW13 postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. SW13 fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| SW13 | Barnes | Georgian villas, Edwardian terraces | A drawing package at an SW13 address in Barnes is determined by Richmond Council under its own Local Plan policies for Barnes. |
| SW14 | Mortlake / East Sheen | Edwardian villas, 1930s semi-detached | Adjoining district to SW13, also inside Richmond upon Thames for drawing package purposes. |
| TW1 | Twickenham | Georgian fragments, Victorian terraces, Edwardian villas | Adjoining district to SW13, also inside Richmond upon Thames for drawing package purposes. |
| TW2 | Twickenham / Whitton | Georgian fragments, Victorian terraces, Edwardian villas | Adjoining district to SW13, also inside Richmond upon Thames for drawing package purposes. |
Roof pitch, wall build-up and plot depth change every few SW13 streets, and each one changes what a drawing package can achieve at that address.
SW13 (Barnes) conservation designations: there are 72 across Richmond Council, Barnes Village, Ham Common, Richmond Green among them. Designation costs a SW13 (Barnes) owner the permitted-development route: a drawing package then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. Barnes Village is the SW13 (Barnes) designation that most often changes a drawing package design.
Article 4 and your SW13 (Barnes) drawing package: Richmond Council has made no borough-wide direction, so permitted development for a drawing package in SW13 (Barnes) generally survives outside SW13 (Barnes) conservation areas and listed curtilages. A Lawful Development Certificate at £274 is how a SW13 owner records that a drawing package was lawful.
SW13 (Barnes) housing stock: Georgian in Richmond Green and Twickenham; Edwardian villas in Barnes and East Sheen; 1930s semi-detached in Whitton; riverside cottages along the Thames. Highest conservation area coverage in London; Royal Parks and Thames corridor add heritage layers; design quality heavily scrutinised. Read that before choosing a drawing package route in SW13 (Barnes) — construction, not postcode, sets what is achievable.
