Used BestBuilders to find a loft specialist near Sherborne - final pick was the team with the longest workmanship guarantee. Builder did the structural drawings and party wall notices in-house. Skip changeovers timed for weekends, never an issue with the road outside. Final bill ยฃ50960. Family of five comfortable in a house we nearly outgrew.

โ˜…โ˜…โ˜…โ˜…โ˜…

A full freeze-thaw cycle later, no movement around the new dormer cheeks. Builder we found via BestBuilders in Sherborne recommended a slightly larger dormer than we asked for - they were right. Total ยฃ61640. Working from home is so much better with the proper office light.
