Attics & Extensions — common questions
Will my attic conversion need planning permission?
Most attic conversions within the existing roofline are exempt, but dormers often are not. We flag it clearly at quote stage.
Do you do the roofing as part of the extension?
Yes — flat or pitched, tied into the existing roof by our own crew rather than subcontracted out.
