Question 1

What does a rear kitchen extension cost on an interwar semi in Barking & Dagenham (IG11, RM8, RM9)?

Accepted Answer

Budget roughly £28,000–£50,000 for a single-storey rear extension on the semi-detached and terrace stock across IG11, RM8 and RM9 — the range shifts depending on footprint, whether a WC or utility room is included, and how much of the existing rear wall comes down. Rolling a kitchen refit into the same programme is common and typically adds £12,000–£25,000. A two-storey rear addition sits in a different bracket — around £60,000–£90,000 — and requires a full planning application rather than a permitted-development certificate. PrimeCraft provides a line-by-line cost breakdown on the day we visit, so there are no broad estimates to second-guess later.

Question 2

Does a dormer or hip-to-gable loft conversion on a Barking & Dagenham semi need planning permission?

Accepted Answer

For most semi-detached and end-of-terrace properties across RM8, RM9 and RM10, a rear-facing dormer or hip-to-gable conversion qualifies as permitted development — what you need is a lawful development certificate, not a full planning submission. Exceptions include conservation area streets and any corner plot where the roofline faces a public highway. Mid-terrace properties can add a rear dormer under permitted development but cannot do hip-to-gable work. At our initial survey we look up the planning designation of your specific road and confirm what route applies before any design is drawn up.

Question 3

How does the Party Wall etc. Act 1996 affect renovation work on the Becontree estate's attached properties?

Accepted Answer

Barking & Dagenham's attached housing — pairs and short rows of 1930s properties throughout IG11, RM8, RM9 and RM10 — means rear extensions and structural loft work almost always engage the Party Wall Act, since the works bear on or excavate close to the shared boundary. Written notice must go to the adjoining owner before construction starts — typically a month or two ahead, depending on the exact scope. If the neighbour appoints their own surveyor, a formal party-wall award must be agreed before the build commences. PrimeCraft prepares and serves all required notices as part of the project programme.
