When a room suffers from natural light, removing part of the wall and replacing it with black-framed glass is a good solution. It creates the feeling of space, allows light to travel through yet still establishes the division between rooms. Using frosted or reeded glass to increase the level of privacy. 'When putting glass internal doors, we’d recommend having two horizontal bars, not three. When you have three, the handle can end up being too low and you risk having to bend down slightly,' recommends Dan Smith of Minima Interior, an internal doors and glass partitions company.
