Office building Salamanca, designed by Rietveld Architects of New York, is a light and transparent structure with striking, geometric forms. The front facade of the office block is about 2,5 meter forward of the vertical. To this end, the row of columns on this side is also inclined forward, some 0,5 meter per floor. By combining casting and prefabrication, it was possible to avoid having to scaffold the entire structure and to gradually build at an angle from floor to floor.The main entrance hall leads to a glass space that has a void over the full height of the building. Each floor joins this void in an open connection. The sloping facade gives an exciting feeling when you reach down and look over the glass balustrade.
