The hyperbolic paraboloid form has been used for roofs at various times since it is easily constructed from straight sections of lumber, steel, or other conventional materials.[1] The term is used because the form resembles the shape of a saddle. Sometimes referred to as a hypar, the saddle roof may also be formed as a tensegrity structure.[2] Mathematically, a saddle shape contains at least one saddle point. You can see from the pictures, the roof was made of long straight pieces of wood. A good example of a hyperbolic paraboloid is a Pringle.
