Open concept and minimalist house designs are becoming increasingly popular. Visual barriers in main living areas are avoided with simple design elements usually defined just with vertical and horizontal planes. And stairs are learning that orthographic language. No ornamentation, no intricate curves. Stairs are going naked. They are losing walls and massive supports and they are often moved closer to the center of the house living area to become a focal point of the whole house. They become just a set of seemingly unsupported step platforms in a plain orthogonal shape. No visible screws, brackets, welds, etc. For maximum transparency step supports are either hidden or visually minimal.
The simple rhythm of step platforms, climbing diagonally up, grabs attention and a stair becomes a modern sculpture.
