Start a free quote →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.
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.
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.
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.
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.
