Planning and building regulation drawings in Teddington (TW11)

Teddington is mostly terraces and semis, with Victorian and Edwardian streets gathered around an older village centre. Manor Road and Cambridge Road are examples, and Watts Lane and Clarence Road are among its other streets. Nearer the river the stock turns to older cottages by Teddington Lock, and towards Broom Water the houses become larger villas. For a homeowner that range means the question of how much space a particular house can take has a different answer depending on which part of TW11 you are in.

On a terrace or semi outside the conservation areas, a rear or side-return extension or a loft conversion starts from the permitted development limits. The old village core and the riverside are handled more cautiously, because the council has drawn conservation areas around High Street Teddington, Teddington Lock, Broad Street and Park Road Teddington, and it treats frontages, shopfronts and the riverside setting as things worth protecting. Houses beside the Thames can also fall within a flood zone, which affects how a ground-floor extension is designed.

Richmond uses Article 4 directions across its Teddington conservation areas, including one on Clarence Road in the Park Road Teddington area. Where a direction applies, work such as new windows, roof changes and front boundaries needs permission that would not normally be required. We check the conservation boundary, any direction and the listing position for your address before advising, so you know early whether a project is simple or needs a full application.

Planning in Teddington: what to know before you apply

Richmond assesses householder proposals against the character of each conservation area, and Teddington has four of them. The Article 4 direction on Clarence Road removes permitted development rights for changes to windows, roofs and front boundaries, so those need planning permission there. Elsewhere, in any conservation area, roof enlargements, side extensions and rear extensions of more than one storey are not permitted development, and flats have no householder rights at all. The High Street and Broad Street frontages come with their own shopfront controls. Near Teddington Lock, flood-zone and outlook points are weighed alongside the design. An application needs an ownership certificate or notice, not the freeholder's consent. We confirm the exact constraints for your address before drawing.

Applications are decided by London Borough of Richmond upon Thames — its planning pages.

  • A single-storey rear extension up to 4 m deep on a detached house, or 3 m on any other house, is Class A permitted development subject to the height and materials conditions.
  • An Article 4 direction applies here and may withdraw this freedom — the schedule must be checked before relying on it.
  • One or more constraints are unknown — we check the council's registers as part of the free appraisal.
  • Where permitted development applies, a lawful development certificate proves it for lenders and buyers.

FAQ

Teddington (TW11) — FAQs

Does Clarence Road have extra planning controls?+
Yes. A direction applies there, within the Park Road Teddington conservation area, removing rights for changes such as windows, roofs and front boundaries. Work like that needs a planning application. We check the current position for your house before recommending a route.
Do I need to worry about flooding if I live near Teddington Lock?+
It is worth checking. Properties near the riverside may be in a flood zone, and the council weighs that along with the outlook and setting. Where it applies, we reflect it in the design of any ground-floor extension so the application is complete when it goes in.
