Our hall and landing never get daylight. Is a sun tunnel the answer?
A hall or landing in the middle of a house may have no outside wall to put a window in. A sun tunnel is made for that. A small dome on the roof collects daylight, a tube carries it across the loft, and a diffuser in the ceiling spreads it below. For that to work the ceiling has to be opened for the diffuser, and the loft above has to give the tube a clear run. We look in the loft before we say yes, because a water tank, a joist or a bend can decide it.
On a tiled low-pitched roof
Concrete interlocking tiles on a low pitch are common on council estates of the 1950s and 1960s. The dome sits on a flashing chosen to match the tiles. Our page on rigid and flexible sun tunnels compared explains the two kinds of tube, since a straight run and a bent one suit different types.
What it does and does not do
A sun tunnel brings in daylight. It does not open, it gives no view, and it needs no blind. That suits a hall, a landing or a bathroom, where you pass through or wash. If you want a room to open or to see the sky, a small roof window is a better choice, and we say so at the survey. The page on rooms that take a sun tunnel well names the usual ones.
Everyday care
The dome is outside and on a slope, so its cleaning is a question about your roof. We explain it at handover, and we say plainly if the answer is that someone has to go up there now and then.
Hall, landing, bathroom
Where nobody sits and nothing needs to open, light from the roof can do the job without a window, and with no handle to reach.
