Reinier de Jong Design has designed and recently finished a staircase design named DUB. But, these are no ordinary stairs. Upon closer inspection, from underneath these steps are two steps in one! There are eight white blocks and sixteen gray steps, looking more and more like a contemporary sculpture than a simple functional staircase. The stairs are functional, though, leading to a roof terrace in a large apartment. The stairs are flanked by an aluminum and glass balustrade, adding to the airy quality of the stairs.
