Timber Stadium is a 2007 dRMM research project for a 100m diameter covered arena to seat 6,000 people. Designed entirely in engineered timber, this would be the world’s first flatpacked, demountable, carbon-negative stadium. The proposal marks a step change in the ambition of all-timber architecture.
The design exploits CAD geometry and timber CNC cutting processes to produce an optimised stadium structure with minimum material and waste. The entire structure is cross-laminated mass-timber panels, with a steel cable truss roof span of 100m, and 50% composite plywood, 50% ETFE variable skin roof.
The interior is characterised by adaptability and accessibility: sports pitches at grade, 6,000 seats as mobile-retractable clusters; pedestrian and installation vehicle traffic can enter all around the perimeter; ETFE cable roof structure offers daylight control and multi-point suspension to allow open plan multi-use space. This is not a specific steel box but a flexible timber bowl, derived from the need for flexibility, economy, and ecology.
