Covering Acton
Site visits are available across Acton (TW8, W3, W4, W5, W12, W13). We also work in nearby Chiswick (1 mile), Harlesden (2 miles), Shepherds Bush (2 miles), Willesden (2 miles).
In London, space is at a premium and gardens are often short, so side returns, wraparounds and carefully planned rear extensions tend to make the most of every metre.
Planning rules that apply in Acton
In England a single-storey extension to a bungalow follows the normal permitted development limits (3 m or 4 m, or 6 m and 8 m through prior approval). Adding a first floor always needs planning permission.
The planning position for a specific Acton address depends on its history and any designations, which is why we check it at the first visit.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Applications are decided by the local planning authority (your district, borough or unitary council).

Common questions in Acton
How long does a bungalow extension take to build in Acton?
On site, typically 10 to 18 weeks once approvals are in place. Before that, allow 6–14 weeks design and approvals.
Do you cover all of Acton?
Yes. We cover Acton and the surrounding parts of Greater London. Site visits are free and there is no obligation.
Do I need building regulations approval in Acton?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
How much does a bungalow extension cost?
Our guide range for single-storey work is about £2,280 to £4,420 per m² including VAT. Going upwards is priced after a structural survey.
Is it better to extend sideways or upwards?
Sideways and rearwards is usually simpler, cheaper and keeps single-level living. Upwards saves garden but means stairs, more structure and planning permission.
