Many converted farm buildings sit under planning conditions. The conversion itself may have been approved with limits on new openings, so check what was agreed before choosing windows. South Gloucestershire Council can tell you what applies to your plot, and if the building is listed the same consent rules as for cottages apply.
The inside of a barn matters as much as the outside. Beams that were left on show look best when the daylight falls along them, and a roof window placed between two rafters will do that without any need to cut through a main timber. We plan the layout so that no structural member is weakened, and where the roof structure does need trimming around an opening, it is formed properly and tied back in.
Newer houses and garden rooms
On the village edges, newer houses make up the rest of the picture. Their extensions are usually flat-roofed and sunny, built to look out over a garden or a paddock, and they have the usual trouble: a large fixed pane warms up faster than the room can shed heat. An opening flat rooflight or a roof lantern that vents lets that heat leave from the very top.
Reaching a handle on a high roof is not realistic, so motors do the work. Our electric opening rooflights page covers the choice between mains and solar. A sensor that detects rain closes the unit, which is a real comfort in open country where weather can arrive across the fields with little warning. Our comparison of electric and solar helps with that decision.
Older rooflights on extensions and outbuildings deserve a look too. Misted glass, a sagging frame or a seal that no longer holds are all signs that a unit has reached the end of its life, and our misted and failed rooflights hub explains the replacement options. Some can have just the glass changed, while others need the whole unit replaced.
The costs guide shows what pushes a price up or down, and nearby Frampton Cotterell and Yate are covered by the same team.
