Working in Bethnal Green
Our survey diary covers Bethnal Green, including E1, E2, E8, EC2A, EC2M, EC3A. Nearby, we also take on projects in Stepney (1 mile), Bow (2 miles), Highbury (2 miles), Stratford (3 miles).
Waltham Abbey, in Essex, is roughly 11 miles from Bethnal Green and also on our list. Across London, terraced houses with narrow side returns and tight access are the norm, which shapes everything from party wall notices to how materials reach the back garden.
Will the council need to approve it?
In England a wraparound extension is assessed as both a side and a rear extension, and the combination usually falls outside permitted development, so most need a householder planning application (£548 from 1 April 2026).
The planning position for a specific Bethnal Green address depends on its history and any designations, which is why we check it at the first visit.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).
When a wraparound extension makes sense
- Terraced houses that want the largest ground floor possible
- Semi-detached houses with a side passage
- Families who want kitchen, dining and living in one space
The corner is where wraparounds succeed or fail. We usually use a single steel goalpost or a corner post hidden in a pier, and set the glazing so the new room reads as one space rather than two boxes.

Your questions about a wraparound extension in Bethnal Green
How long does a wraparound extension take to build in Bethnal Green?
On site, typically 14 to 20 weeks once approvals are in place. Before that, allow 8–16 weeks design and approvals.
Will my neighbours in Bethnal Green be involved?
If a planning application or prior approval is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
Do you cover all of Bethnal Green?
Yes. We cover Bethnal Green and the surrounding parts of Greater London. Site visits are free and there is no obligation.
Is a wraparound better than a side return alone?
It adds far more space, but costs more and needs planning permission more often. Our comparison guide sets the two side by side.
Do wraparound extensions need planning permission?
Usually, yes. In England the side element counts as a side extension and the rear element as a rear extension, and the combination normally falls outside permitted development. A householder application costs £548 in England from 1 April 2026.
