Loft conversion areas

Planning resources

Planning a loft project? Read our guide to preparing for a loft conversion survey so you know what information to gather and what to discuss at the visit.

Compare loft options before choosing finishes

Start with the rooms you need, the stair position and how the new floor will connect to the occupied house. Use the survey findings to compare a dormer loft conversion with a mansard conversion where suitable. Discuss structure, fire safety, insulation and service routes before fixing the room layout. If the work also changes the floors below, include those rooms in the renovation brief so the related work can be considered together.
