The protected shell building by structural engineer Ulrich Müther in Magdeburg, Germany, is set to be refurbished by Architects von Gerkan, Marg and Partners (GMP). The building, called Hyparschale, is one of approximately fifty shell buildings by Ulrich Müther, whose work had a major impact on modern architecture that is still in existence, and dates from 1969.
The building has stood empty for over two decades and gmp will be refurbishing it in line with monument preservation guidelines. It will be revived into an events and exhibition venue, and special focus will be given to repairing the concrete shell roof.
The plans for the design show that gmp aims to revive the multifunctional hall, which has not been used since 1997 and is badly dilapidated, to recreate a multifunctional events and exhibition venue. Besides re-establishing the interior spatial effect of the shell roof, the project aims to strengthen the ensemble of the Hyparschale and the City Hall.
The original design of the concrete roof consists of four hyperbolic paraboloids. With the absence of columns inside the hall, the traditional doubly-curved roof surfaces cover an area of 48 x 48m. The loadbearing capacity of the roof will be re-established and even increased, thanks to carbon concrete.
Roof lights running crosswire between the shells will be reopened to provide optimum lighting to the centre of the hall. Building occupants will be able to use and experience the open space with its curved roof in many different ways, thanks to the inserted gallery levels and walk-on bridges that are part of the planned revamp.
The former translucent industrial glazing is replaced by a transparent glass facade, with the original facade construction being retained. The interior steel constructions and facades are reminiscent of the original external facade with its vertical emphasis and industrial steel and glass materials.
Steel and glass materials will be used for the internal facades, which are reminiscent of the original external facade of the building.
