The traditional kind of staircase really does take up an inordinate amount of space that, in a small home really isn't available. Most people just put up with what they have, decorate the staircase and find the best use they can for the under-stairs' area. However, if you are in the market for a new staircase, there is quite an extensive range of home space saving staircases on the market. The cheapest on the market - and also the smallest - is the Karina model which combines either a light or a dark beech wood used for the treads with one of three other colors. As well as being the smallest on the market the Karina is narrow enough to be used as a loft ladder replacement or in other spaces that are too narrow for other, more conventional staircases.
