Do not be afraid! Use the natural beauty of the building. It can be bricks, wood, cement, whatever your house has.
This loft has already been a local stables, a bomb shelter and a print shop. All of that added its character to the building and the new owner was not afraid to use it to make it his home. A lot of people are afraid to use raw materials thinking the house would become too industrial and not cosy. This house proves that there is no need to be afraid of that!
I just LOVE this bedroom and its closet!
