Planning and building regulation drawings in Rainham (RM13)

Rainham pairs a small historic village core with wide belts of newer housing. Near Rainham Hall and the medieval church the buildings are tightly grouped, while out toward the marshes the roads are lined with 1930s and postwar semi-detached and terraced houses. Upminster Road North, Lambs Lane South, Brookway and Elizabeth Road are among the district's streets. Most of these homes are unlisted family houses with generous back gardens, which suits rear extensions, side infills and loft conversions.

The village core is the main exception. Rainham Village conservation area tightens design and materials there, so a project close to the old church is judged differently from one on a postwar road a few minutes away. Havering has no published householder Article 4 direction for the district, which makes that conservation area the principal control. Away from the core, permitted development often applies to the interwar and postwar stock, and the question becomes whether the proposed work stays within the limits.

Being near the marshes and the Thames floodplain adds another consideration. Lower-lying plots can raise surface-water and flood-risk questions, which may need to be addressed as part of an application. Mature street trees along the residential avenues can also carry tree preservation orders or root-protection implications, so siting a rear extension or a new access requires a look at what is growing nearby before the design is fixed.

Planning in Rainham: what to know before you apply

Havering handles Rainham householder work through its standard rules, with Rainham Village conservation area as the one area control. Inside it, roof enlargements, side extensions and rear extensions of more than one storey are not permitted development, and officers pay close attention to materials and the historic setting. Elsewhere, interwar and postwar houses often keep their permitted development rights, so a rear extension or loft that stays within the limits can avoid an application. Lower-lying plots near the marshes may trigger flood-risk and surface-water questions, and protected street trees can alter where an extension or access can go. Flats have no householder permitted development rights. We check these points for your address before drawing.

Applications are decided by London Borough of Havering — 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.
  • This council does not publish its Article 4 directions to the national register, so the schedule is confirmed with the council first.
  • 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

Rainham (RM13) — FAQs

Is flood risk a problem for an extension in Rainham?+
It can be on lower-lying plots near the marshes and the Thames floodplain. We check the flood and surface-water position for the address early, since it may shape the floor levels and the drainage drawings.
Will the Rainham Village conservation area affect my house?+
Only if the property lies within it. The designation covers the historic core, and the boundary is checked against your address, because it decides whether roof and side work needs an application.
