Many rear dormers may qualify as permitted development, subject to the house and design meeting the relevant limits. Front dormers usually need planning permission. Check roof enlargement volume, previous additions and local requirements with your council or the Planning Portal before proceeding, so you always know what happens and when.
Some households remain at home during construction, but suitability depends on access, roof-opening work and the agreed programme. Discuss the work sequence and household arrangements before accepting the quote, so you can plan around the construction period.
A dormer can provide space for a bedroom and en-suite when the measured floor area and layout support both. The design needs to account for stairs, drainage and ventilation. A home visit helps establish whether your roof space can accommodate the plan.
