The stairs in our stone terrace have no window. How do we get daylight down them?
Glossop's early houses were solid and built of local stone, and in a house like that a stair or landing can have no window at all. The roof is then the only way to bring daylight in, and there are two sensible routes.
A sun tunnel
A sun tunnel is a daylight pipe: a dome out on the slope, a tube through the loft space and a frosted panel flush with the landing ceiling. It suits a stair, a hall or a bathroom with an unused loft above it. Nothing about it opens and it shows no sky, so it solves darkness and nothing else. The panel in the ceiling wipes clean from inside the house, and we explain at handover how the dome on the roof is looked after. The guide to rooms a sun tunnel suits shows where it works, and the page on rigid or flexible sun tunnels explains the tube.
A roof window over the stair
If the loft has been made into a room, the daylight can come through a roof window in the slope, or the stair can borrow light from the room above. A roof window opens, which a sun tunnel cannot, and that matters on a stair that gets warm. It also needs reaching: over a stairwell the handle can be well out of arm's length, so we talk about a rod or a motor.
Which suits you
A narrow landing suits a sun tunnel. A wide stair with a room above can suit a roof window better. We make the call at the survey, once we have seen the loft.
Light for a windowless stair
A sun tunnel lights the stair. A roof window lights it and lets you open it, if you can reach the handle.
