Question 1

What does a single-storey rear extension cost in Forest Gate (E7) in 2026?

Accepted Answer

On a late-Victorian or Edwardian terrace in E7, a single-storey rear extension — groundworks, structural frame, flat or pitched roof, insulation, plastered-out shell — typically runs £44,000 to £68,000. Scheduling a kitchen refit in the same programme saves money compared with treating them as separate contracts, because scaffolding, skips, and site management are already priced in. We issue a fully itemised written quote on the day of the site visit, listing every cost separately so you can adjust scope before any work is confirmed.

Question 2

What are the permitted-development rules for rear extensions on terraces in Newham (E7)?

Accepted Answer

Residential streets across Forest Gate E7 fall under Newham Council's jurisdiction. Under national permitted-development rights, a single-storey rear extension of up to 3 metres on a semi-detached or terraced house can proceed without a full planning application. The larger home extension scheme raises that limit to 6 metres on a terrace and 8 metres on a detached property under a prior-approval neighbour consultation route. There is no Newham-wide Article 4 direction removing these rights from Forest Gate's main residential streets, though individual conservation areas and locally listed buildings may impose additional controls. We check your exact address before any drawings are commissioned.

Question 3

Are rear-dormer loft conversions viable on Victorian terraces near Wanstead Flats in E7?

Accepted Answer

Most late-Victorian terraces within E7 have ridge heights comfortably above the threshold needed for full standing headroom once a rear dormer is installed — the original roof pitch was generous by modern standards. A dormer positioned on the rear slope typically falls within permitted development, avoiding the time and cost of a full planning application. Houses on wider corner plots or double-fronted avenues approaching the Wanstead Flats boundary sometimes support a more substantial conversion. We inspect the roof space on the initial visit and confirm what is structurally and planning-wise achievable before quoting.
