Do I need planning permission in Colchester?
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.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
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).

Questions people ask about bungalow extensions
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Colchester, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.

Who do I contract with for a bungalow extension in Colchester?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
How much does a bungalow extension cost?
Our guide range for single-storey work is about £1,860 to £3,600 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.
