Frequently asked questions

Will I need to move out during the build?

Almost never. We separate the work area from your living space and keep disruption to a minimum.

Do I need planning permission for an extension?

Many extensions fall under permitted development, but it depends on your property. We’ll check this for free at the survey.

How much does a rear extension cost?

Most single-storey extensions fall between £2,200 and £3,200 per m². We’ll give you a firm fixed price after a free survey.
