Two custom designed loft beds carefully integrated into the bedrooms of an apartment in a converted industrial building. The alternate tread stair was designed to be a perfect union of functionality, structure and form. With regard to functionality, the stair is comfortable, safe to climb, and spatially efficient; the open sides of the stair provide ample and well-placed grip locations. With regard to structure, the triangular geometry of the tread, riser and stringer allows for the tread and riser to be securely and elegantly fastened to a single, central, very minimal stringer.
