Moberly House, University of Exeter
Scaling safety and style with bespoke multi-storey escape stairs for the University of Exeter.
The redevelopment of Moberly House at the University of Exeter involved replacing a 1960s residence with a 251-bedroom development requiring four external, Category E-compliant spiral staircases. These structures needed to function as secure, durable escape routes for high-volume public assembly while complementing the modern, H-shaped campus architecture.
