Every TW11 postcode district we draw in, the stock that dominates it and the authority that validates a drawing package there. TW11 fees below are the statutory England rates for 2026, not drawing package estimates.
| Postcode | Area | Dominant stock | What it means for a drawing package |
|---|---|---|---|
| TW11 | Teddington | Edwardian villas, Victorian terraces | TW11 covers Teddington only; Richmond Council handles the drawing package. |
| SW13 | Barnes | Georgian villas, Edwardian terraces | Adjoining district to TW11, also inside Richmond upon Thames for drawing package purposes. |
| SW14 | Mortlake / East Sheen | Edwardian villas, 1930s semi-detached | Adjoining district to TW11, also inside Richmond upon Thames for drawing package purposes. |
| TW1 | Twickenham | Georgian fragments, Victorian terraces, Edwardian villas | Adjoining district to TW11, also inside Richmond upon Thames for drawing package purposes. |
| TW2 | Twickenham / Whitton | Georgian fragments, Victorian terraces, Edwardian villas | Adjoining district to TW11, also inside Richmond upon Thames for drawing package purposes. |
Roof pitch, wall build-up and plot depth change every few TW11 streets, and each one changes what a drawing package can achieve at that address.
