Question 1

What does a rear extension cost on a Victorian terrace in Hackney Central (E8 or E9)?

Accepted Answer

A single-storey rear extension on an E8 or E9 terrace — groundworks and foundations, structural frame and flat or pitched roof, bi-fold or sliding doors, internal plastering and linking the new space into the existing layout — typically falls between £50,000 and £82,000. Including a full kitchen refit within the same programme adds roughly £12,000 to £22,000 depending on the specification. We split the cost across separate trades and materials lines so the breakdown is transparent, and you receive the full itemised figure on the same day as the site visit.

Question 2

When does the Party Wall Act apply to a rear extension in Hackney Central (E8/E9)?

Accepted Answer

Any extension that builds at or close to the shared rear boundary triggers formal Party Wall Act obligations — written notices must reach the affected neighbours well before groundworks begin, typically eight to twelve weeks ahead. On the dense terrace streets of E8 and E9 a shared rear boundary is the norm rather than the exception, so this is a routine part of planning the project rather than an unusual step. PrimeCraft prepares and serves the notices, co-ordinates with any surveyor a dissenting neighbour appoints, and sequences the build so the agreement is confirmed before any excavation starts.

Question 3

Are there Article 4 directions or conservation areas in parts of Hackney Central (E9) that affect renovation work?

Accepted Answer

Yes — certain sections of E9, particularly around Well Street Common and toward the Homerton boundary, sit within conservation areas or carry Article 4 directions that remove permitted development rights. In those zones, changes to the external appearance of a property — window replacements, new render, roof alterations — need a formal planning application rather than a simple notification. We check every E8 and E9 address against Hackney Council's current conservation and Article 4 boundary maps at survey stage and advise you precisely which consent route applies before any work is costed.
