Where on a long rear slope should a loft window go?
A long, uninterrupted rear slope is the friendliest roof a loft conversion can have. With the slope uninterrupted, the window can go where the room wants it rather than where the roof allows.
Height up the slope
A window set low gives a view from a chair or the bed, and its handle is easier to reach. A window set higher puts light deep into the room, but the handle rises with it. If you choose high, plan the opening method at the same time: a rod, a remote or solar opening. A window you can only open with a stepladder is a window that stays shut.
Slate and the flashing
Natural slate needs a flashing kit made for it, and the kit is chosen when the window is ordered. The page on flashing for slate and tile explains the difference. The rafters matter too, because they set how wide the opening can be without extra framing.
Blinds in a bedroom
A loft bedroom on a long slope can get sun for much of the day. A blackout blind is the usual choice for sleeping, and one that runs on the window's own remote is the one that gets used. The blinds and controls page sets out the types.
If it is a conversion
Turning the loft into a room counts as building work, and everyone on the new floor must have a safe route out, which is settled in the design of the stair. The Building Regulations guide explains what to expect. The window positions follow from that. Our page on roof windows for loft conversions goes into sizes and positions.
