Every Richmond upon Thames postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. Richmond upon Thames 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 | Mortlake / East Sheen sits wholly inside SW14, so Richmond Council validates every drawing package submitted from an SW14 address. |
| TW1 | Twickenham | Georgian fragments, Victorian terraces, Edwardian villas | A drawing package at an TW1 address in Twickenham is determined by Richmond Council under its own Local Plan policies for Twickenham. |
| TW2 | Twickenham / Whitton | Georgian fragments, Victorian terraces, Edwardian villas | Twickenham / Whitton sits wholly inside TW2, so Richmond Council validates every drawing package submitted from an TW2 address. |
| TW9 | Richmond / Kew | Georgian terraces, Victorian villas | TW9 covers Richmond / Kew only; Richmond Council handles the drawing package, and Richmond / Kew case officers apply the TW9 conservation-area map. |
| TW10 | Richmond / Ham | Georgian terraces, Victorian villas | Richmond / Ham sits wholly inside TW10, so Richmond Council validates every drawing package submitted from an TW10 address. |
| TW11 | Teddington | Edwardian villas, Victorian terraces | TW11 covers Teddington only; Richmond Council handles the drawing package, and Teddington case officers apply the TW11 conservation-area map. |
| TW12 | Hampton / Hampton Hill | Georgian villas, Edwardian terraces, 1930s semi-detached | A drawing package at an TW12 address in Hampton / Hampton Hill is determined by Richmond Council under its own Local Plan policies for Hampton / Hampton Hill. |
Roof pitch, wall build-up and plot depth change every few Richmond upon Thames streets, and each one changes what a drawing package can achieve at that address.
Richmond upon Thames conservation designations: there are 72 across Richmond Council, Barnes Village, Ham Common, Richmond Green among them. Designation costs a Richmond upon Thames 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. Twickenham Riverside is the Richmond upon Thames designation that most often changes a drawing package design.
Richmond upon Thames permitted development status: there is no borough-wide direction from Richmond Council, so a drawing package at a SW13 address is normally still permitted development. We certify that with a £274 Lawful Development Certificate rather than leaving a Richmond upon Thames sale to argue it later.
What Richmond upon Thames is built from: 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. That mix decides the drawing package route in Richmond upon Thames more than the postcode does, and it is what a Richmond Council case officer reads first. A householder application costs £548 paid to Richmond Council direct, with 8 weeks to a decision once validated.
