Frei Otto is considered one of the most influential architects of the 20th century. Whilst his work is primarily characterised by constructive boldness and structural lightness, it equally stands for new dawnings, pluralism and freedom. The interplay of construction, poetry and visionary thinking is what makes his buildings so fascinating right up to the present day. Frei Otto was posthumously awarded the Pritzker Prize for Architecture for his life’s work, in 2015. One of Otto’s most significant buildings is based on a design by architect Carlfried Mutschler and his business partner Joachim Langner: the Multihalle in Mannheim’s Herzogenriedpark. Initially constructed as a temporary hall to accommodate plants at the 1975 National Garden Show in Mannheim, Germany, the world’s largest timber grid shell roof, with its spatial and architectural allure, is still regarded as a sign for a democratic move towards change – as a “huge festival that put our city on the map”, as a local resident and contemporary witness put it. Long after the National Garden Show had ended, the hall served as a prestigious venue for major political, media and commercial events. During the 1980s and ’90s it experienced a steady decline in appeal as its architectural structure could no longer satisfy the growing requirements of acoustics, fire protection and climatic comfort. Finally, structural problems and static deformations necessitated a partial closing of the hall, upon which the preservation of the entire construction was called into question.
A broad and prominent circle of supporters formed in protest against this and, in 2017, a political decision was taken to renovate and reuse the Multihalle, thus opening a new chapter in its history.
This competition is a further significant step. The outcomes should not only make it possible to preserve the Multihalle’s architectural structure, but also – and above all – to reinterpret and continue into the future Frei Otto’s ideals, which are manifested in the building and had a major influence on its creation. The designs should take into account not only the urban landscape around the hall and its leisure uses, but also the social integration of the neighbouring districts and Mannheim’s vibrant cultural scene.
Frei Otto’s visionary concept for utilization of the Multihalle is to be updated as an experimental urban laboratory and open space for an open society where Mannheim’s citizens can come together for sports, leisure and cultural activities, and to thereby establish the basis for a social laboratory in which pioneering methods and forms of urban coexistence can be developed and explored. The Multihalle’s roof construction should not only provide the necessary setting for this visionary use, but also symbolise the idea of a “Democratic Umbrella” in public perception through its iconographic architecture.
The objective of this competition is therefore to design new utilization options for the Multihalle and to express these through its architecture. Future utilizations should comprise permanent and temporary elements and also offer usage options that build on the individual design idea – in the spirit of Frei Otto, Carlfried Mutschler and Joachim Langner, who already envisaged the social and architectural future from their contemporary viewpoint. For this reason, the explicit opening of the competition to Master’s students, graduates and young architects aims to inspire a demographic shift of social responsibility towards the younger generations of architects.
The Multihalle is to serve as a venue for diverse events in the coming years – as a result of Mannheim’s already initiated re-identification process with it, and simultaneously with project development and renovation planning. In order to think the concept of utilization further forward and to develop it as a socially relevant and future-oriented location within the urban fabric of Mannheim, it needs to offer a space that can be used all year round. This – public – space should depict and represent social realities, and also be able to initiate processes of social change. The desired outcome is to extend the sphere of influence of the existing architecture beyond the actual construction process, so that planning, construction, use and discourse are parts of a democratic and participatory process. For the awarding authority, this synthesis gives rise to the idea of the Multihalle as a “Democratic Umbrella” for a future urban society.
SPACE UTILIZATION CONCEPT
The following space utilization concept is to be understood as a minimum requirement and can be extended according to requirements and the concept.
An adaptable and process-oriented implementation can be proposed for optionally planned spaces. All design proposals should consider a high degree of flexibility and variability within the structure. It is possible to plan areas for seasonal and year-round uses, though year-round operation is generally preferred.
Minimum requirements (year-round)
- Large function room for 300 – 500 people, which can be extended or separated off with temporary subdivisions into smaller units with different characteristics
- Open spaces or rooms with different configurations/features for temporary or future use.
- Foyer for approx. 100 persons
- Office space in various forms and scenarios for approx. 20 – 30 workplaces and corresponding meeting rooms
- Three workshop rooms for different uses and between 5 – 25 persons per room (with variable expansion options)
- Studios for performing arts, media, music and temporary university use
- Storage areas for event equipment and furnishings
- Catering area, also to be used for events for approx. 200 persons, with corresponding kitchen and storage areas Kitchen suitable for community and neighbourhood cooking
- Appropriate number and placement of sanitary facilities (WC) and infrastructure areas
- Additions according to requirements / Continuation of the interior
- Sport and leisure options (to tie in with the north-eastern green corridor)
- Statements on how to handle the borders
