Our railway-era terrace has a spare loft room. Which window would we actually use?
Brick terraces from the railway years tend to be roofed in Welsh slate. Where the rear slope is unbroken, a roof window can go in anywhere along it that the rafters allow. It also puts the window a long way up, since the slope starts at the eaves and rises over a landing or a bedroom. At the survey we look at the covering, because the flashing kit is chosen to suit slate, and at where the rafters fall, because they set the width. We also look at the room below. A landing or a box room that only gets light from a stairwell can brighten a good deal with one window above it, and a bedroom needs more thought about glare and shade.
How high is too high
If the top of the window sits near head height, a handle on the frame is enough. Higher than that, a telescopic rod will do for a window opened now and then. If a teenager or a guest will open it daily, a remote-controlled electric window or a solar one saves the effort. Solar windows need no cable, which matters if the ceiling has just been plastered.
Blackout, filter or nothing
A loft bedroom is where a blackout blind is usually wanted. On a high window the blind has to work from a remote or a pole, or it will be left open. A landing window can often do without one. The page on fitting blinds and remotes to high windows sets out the choices.
Planning the loft as a whole
Turning a loft into a bedroom is building work. A safe way out of the new floor has to be planned with the roof windows, and the Building Regulations guide explains it before you talk to a designer.
