Roof for the Multihalle (multi-purpose hall) in Mannheim
Mannheim, Germany · 1970–1975

A prime precedent for lightweight timber gridshell design and organic, double-curved vaults. Frei Otto's Multihalle roof demonstrates how thin timber laths can be woven and tensioned to span vast, column-free spaces with minimal material.
- What we like about this project
- The dramatic, sweeping archway that frames the transition between the interior walkway and the outdoor landscape.

- Geometry
- Double-curved timber gridshell forming an organic, vaulted canopy. The structure is composed of a lattice of thin laths bolted together, curving in multiple directions to form a self-supporting shell.
- Facade system
- Open-sided structure with a translucent membrane skin over a timber lattice.
- Structural guess
- Doubly-curved timber gridshell supported by perimeter concrete or steel arches and columns.
- Spatial scale
- Large-scale public or multi-purpose hall with a high-clearance ceiling and an elevated walkway scaled for pedestrian flow.
- Lighting
- Diffused daylight filters through the translucent outer membrane, highlighting the intricate pattern of the timber lattice.
- Atmosphere
- A warm, airy, and structurally expressive space where the complex geometry of the ceiling feels both protective and weightless.
- Environmental context
- The structure opens up to a park-like landscape with green trees and low vegetation visible through the open sides.
- Spatial experience
- An expansive, light-filled interior volume sheltered by a soaring, woven canopy. An elevated pedestrian walkway with dark railings cuts through the space, offering changing perspectives of the undulating overhead structure and the ground below.
- Composition rhythm
- The repeating diagonal grid of the timber laths creates a dense, rhythmic pattern that flows dynamically across the curved surfaces.
