Architecture, Building and Structure Design Entry Building to Sberbank Entrance to Headquarters by Evolution Design Entry Building to Sberbank is an entrance building for two adjoining high-rise office towers in Moscow. The building encloses the space between the towers with a hyperbolic paraboloid form, built from 29 steel arches and covered by a glazed triangulated roof. The shape brings daylight inside while limiting sunlight obstruction to the lower office floors. Three floors hold reception areas, restaurants, coffee shops, a conference centre and an event space shaped as a stepped amphitheatre. Both ends are crowned with champagne-coloured stainless steel panels.
