I think it is kinda cool to have items with some story behind. Like antiques, but also furniture built out of wood, or any materials that have been previously used in totally different capacity. When you design a bed frame, or a table to be made out of old barn wood, or railway sleepers-it brings it`s history right into your doorstep.
Logs, beams with the trace of time can make some really awesome looking and solid furniture. Think of a railway sleepers and their past life, trains going over in the direction unknown to you… and now it is a part of your bedroom. I find it cool, somehow mysterious.
It is not very difficult to get your hands on this kind of material. There are plenty of recycled wood depots around any bigger city. I have visited one of them and found plenty of perfect sleepers for a very reasonable price.
