What I think is a very nice detail in some houses are alcoves in the wall. A square or rectangular recess in the wall where you can store things in. Alcoves you see especially in the bathroom, where you can use the nis to your shower stuff to put down. But also in the bedroom you can choose for a niche in the wall, over the bed, as a kind of alternative bedside table. In the kitchen can be a rocky also very useful, as a kind of Board for kitchen stuff, but then more enjoyable.

You can choose different types of nis, for example, a square or rectangular alcoves, the depth of the nis can also differ. You can let blend into the wall in nis causing it almost does not stand out, or leave the niche there is a stand out. You let a nis extra stand out by him to alleviate or the space around the nis by the nis or another colour. In the bathroom you can choose to the nis with other tiles to tile. Need more storage space? Then make several alcoves in the wall.
