Question 1

Do I need planning permission for an extension?

Accepted Answer

Many single-storey extensions fall under permitted development, but it depends on the size and your property. We advise at the survey and handle the application either way.

Question 2

How long does an extension take?

Accepted Answer

A single-storey rear extension is typically ten to sixteen weeks on site, after the design and approvals are in place. We give you a full programme before we start.

As a guide, single-storey rear extensions typically start around £40,000 and rise with size, specification and access. We give you a costed, itemised quote after the survey.

Do you do the drawings and planning?

Yes. We manage the architectural drawings, the planning or permitted development route and building control as part of the job.

Question 5

Are you insured and accredited?

Accepted Answer

Yes. We hold public liability insurance, we are CHAS accredited to the Standard level, our team holds CPD certified training, and we run sites in line with Health and Safety Executive guidance and CDM 2015.
