Planning and building regulation drawings in Twickenham (TW2)

The Twickenham of TW2 is mostly built of bay-fronted terraces and semi-detached villas from the late Victorian and Edwardian years, laid out around Twickenham Green. One planned group is the Rosecroft Gardens estate, an Edwardian development whose streets include Denehurst Gardens and Gladstone Avenue. First Cross Road is the other name that matters here, since part of it lies within the Twickenham Green conservation area.

A bay-fronted terrace or semi of this age can take a rear or side-return extension or a loft conversion, depending on the house. What sets TW2 apart is that two conservation areas, Twickenham Green and Rosecroft Gardens, cover parts of this housing, and Richmond has paired them with Article 4 directions.

In the Rosecroft Gardens conservation area, the direction covers the dwellinghouses on Rosecroft Gardens, Denehurst Gardens and Gladstone Avenue, so permitted development rights are removed and changes that would be routine elsewhere need an application. A separate Article 4(2) direction covers a run of houses on First Cross Road within the Twickenham Green conservation area. Around the Green itself, frontages and shopfronts are controlled, which affects anything converting a shop front.

For a homeowner, the first job is a precise one: find out which house is under which control. Two neighbouring doors can fall on different sides of a boundary or a direction, and the drawings and the application route both follow from that answer.

Planning in Twickenham: what to know before you apply

In TW2 the Article 4 directions remove permitted development rights from the houses in Rosecroft Gardens, Denehurst Gardens and Gladstone Avenue and from the covered section of First Cross Road, so work those rights would otherwise cover needs planning permission there. Inside any conservation area, roof enlargements, side extensions and rear extensions of more than one storey are not permitted development, with or without a direction. The council looks at how a roof, a window pattern or a side addition affects the planned character of the street. Flats have no householder rights, and an application needs scaled drawings, a location plan and a correct ownership certificate or notice. We establish the exact controls on 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

Twickenham (TW2) — FAQs

Can I put a rear dormer on a Rosecroft Gardens house?+
Not as permitted development. Roof enlargements are not permitted development in a conservation area, and the Article 4 direction removes further rights across the dwellinghouses there, so a dormer needs a planning application. We design it to suit the roofs of the street.
Does the Article 4 direction cover every house in TW2?+
No. The directions apply to specific streets in the Rosecroft Gardens conservation area and to a defined run of houses on First Cross Road. Other TW2 addresses may still be in a conservation area, so we check the map for each property before advising.
