Completed house extension project in London — house extensions in London
The brief

What the client needed

A family in Shoreditch approached us for wrap-around extension on a warehouse conversions property. Constraints: respecting streetscape rhythm typical of Hackney, maintaining rear garden depth, and meeting Hackney Council's design expectations for the conservation context (29 conservation areas borough-wide).

Design response

How we designed it

Measured survey week 1. Three design iterations balancing internal layout against external massing visible from neighbours. Two scheme massings tested against Hackney Council's adopted design guidance. Chosen scheme matched existing roof pitch, used matching brick, set the new opening back from the eaves.

Planning route

Submission and decision

Submitted to Hackney Council via the Planning Portal. With Article 4 in force in Hackney, we confirmed our scheme retained the necessary permissions before submission. Officer comments minor, addressed in 5 days. Approved at second round.

Decision recorded Hackney Council, statutory determination period.

Where in Shoreditch does a house extensions actually get determined?

How does a house extensions differ street by street across Shoreditch?

Roof pitch, wall build-up and plot depth change every few Shoreditch streets, and each one changes what a house extensions can achieve at that address.

Does Shoreditch planning policy restrict a house extensions?

Shoreditch conservation designations: there are 29 across Hackney Council, Dalston Lane, Hackney Central, Clapton among them. Designation costs a Shoreditch owner the permitted-development route: a house extensions then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. Stoke Newington is the Shoreditch designation that most often changes a house extensions design.

What Article 4 removes near Shoreditch: Article 4 Direction covers HMO conversions borough-wide and office-to-residential in specific commercial zones. Before pricing a house extensions we check whether the E1 address is inside the mapped area, because Hackney Council draws the Shoreditch boundary street by street rather than across the whole of Shoreditch.

Shoreditch housing stock: Victorian terraces dominate; large post-war estates around Hackney Wick; Georgian fragments in De Beauvoir and Stoke Newington; new-build around the Olympic Park. Young demographic; high design-quality bar in planning; mansards routinely approved in rear-of-terrace positions within conservation areas following the Hackney design guide. Read that before choosing a house extensions route in Shoreditch — construction, not postcode, sets what is achievable.
