Who can reach the glass in a converted cotton mill?
Former cotton mills just outside the centre have been redeveloped as apartment buildings and offices. A mill roof is large, high and often shared. Light for a room beneath it is a design problem as much as a fitting one, and a good survey starts with a long look at the roof from outside and the rooms from within. If you live in one, the roof may belong to the building, so the first step is to ask whoever manages it what you are allowed to change.
Reaching the window
A window in a high ceiling is a window you cannot touch. A manual roof window can be opened with a pole, which suits a window used now and then. For one you open every morning, electric or solar opening is easier. Electric windows are wired to the mains, which is simplest when the ceiling is open. Solar windows need no cable. Our guide sets electric and solar opening against each other.
Blinds that work from the floor
On a tall window a blind is only useful if it runs from a remote or switch. Blackout suits a bedroom, and a light-filtering blind suits an open-plan room that gets bright. A sun tunnel is another route where a dark corridor sits under a roof void, as our sun tunnel pages show.
The outer pane
Glass at that height collects dust, and rain leaves a film. A pivoting window brings the outer pane inside. Others are reached from outside by a ladder or a window cleaner with a pole. We tell you which type you are buying before you order.
Mill-roof rule
Ask who owns the roof before you ask what the window looks like.
