Do I need planning permission for an extension in Newham?

Most standard extensions in Newham fall under Permitted Development — single-storey rear up to 3m (attached) or 4m (detached), side returns up to half the width of the house. However, Newham has Article 4 Directions that may remove these rights in specific streets, and flats, listed buildings and conservation areas always need full planning. We check PD eligibility before quoting.

How big can a rear extension be in Newham under permitted development?

Standard permitted development allows single-storey rear extensions up to 3m (attached house) or 4m (detached) in Newham. Larger extensions up to 6m/8m are allowed under Prior Approval (Class AA). Flats, listed buildings and Article 4 areas in Newham are excluded from these PD rights.

How much does a house extension cost in Newham?

Our fixed-fee architectural package starts at £1,225 for a Newham extension (planning + building regs + structural). Typical Newham build costs are £2,400–£3,500 per square metre including VAT — so a 25m² side return extension is £60,000–£87,500 to construct.

Can I do a basement extension in Newham?

Newham does not have a borough-specific basement policy beyond the national framework — basement conversions are generally permissible subject to structural, drainage and flood-risk considerations. Thames Water Build Over Agreements apply where you're within 3m of a public sewer.

Do I need a side return extension or a rear extension in Newham?

Most Victorian terraces in Newham (particularly in Manor Park) benefit from both — a side return extension infills the narrow side passage to create a wider kitchen, a rear extension projects back into the garden. A wraparound combines the two. We recommend the best option at the free site visit.
