We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.
Do you need planning permission for a two-storey rear extension in Bury St Edmunds?
Here is how the rules in England apply to a two-storey rear extension in Bury St Edmunds.
A two-storey rear extension can be permitted development in England only if it projects no more than 3 metres, stays at least 7 metres from the rear boundary, matches the existing roof pitch and has obscure-glazed upper side windows. In practice most double-storey rear extensions go through a householder planning application.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Bury St Edmunds like to extend?
Bury St Edmunds mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here. In Bury St Edmunds, a two-storey rear extension is worth comparing with the cost of moving once stamp duty, agents' and legal fees are counted.

Two-storey rear extension questions in Bury St Edmunds
Do you handle building control in Bury St Edmunds?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.

Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
Can I add an en-suite upstairs?
Yes. We plan the soil pipe route early so the bathroom sits where drainage works without boxing through the room below.

Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
Is the site visit in Bury St Edmunds free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
