Included in a typical project
- Fire and acoustic details where needed
- Frame design and structural calculations
- Foundations, often lighter than masonry
- Cladding, render or brick slip finish
- Breathable wall build-up with insulation
Moisture is the enemy of any timber building. We design ventilated cladding cavities, breather membranes and a proper damp-proof course height, and keep the frame dry during construction.
Extensions in and around Canning Town
Site visits are available across Canning Town (E3, E6, E13, E14, E15, E16). The same team covers West Ham (1 mile), Stratford (2 miles), Bow (2 miles), Stepney (3 miles), all within easy reach.
For homes towards Kent, Dartford is around 10 miles away. 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.
Planning rules that apply in Canning Town
In England a single-storey rear extension can usually go up to 3 m beyond the original rear wall of a semi-detached or terraced house, or 4 m on a detached house, without a planning application, provided it is no more than 4 m high, keeps eaves to 3 m within 2 m of a boundary and, with other buildings, covers no more than half the land around the original house. The larger home extension prior approval scheme raises those depths to 6 m and 8 m, with neighbours notified and a 42-day decision.
The planning position for a specific Canning Town 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.
Applications are decided by the local planning authority (your district, borough or unitary council).

Your questions about a timber frame extension in Canning Town
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Canning Town, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do you cover all of Canning Town?
Yes. We cover Canning Town and the surrounding parts of Greater London. Site visits are free and there is no obligation.
How long does a timber frame extension take to build in Canning Town?
On site, typically 8 to 14 weeks once approvals are in place. Before that, allow 4–12 weeks design and approvals.
Is timber frame cheaper than brick?
It is similar overall. The frame can save time on site, but the cladding choice has a big effect on cost. Our guide range is about £2,280 to £4,420 per m² including VAT.
Does a timber frame extension need planning permission?
The same planning rules apply as for any extension. If the cladding looks different from the house, permitted development’s matching-materials condition may mean an application is needed.
