Here at Scott Hughes Design we have been responsible for and undertaken structural design and analysis of more than 40 contemporary staircases for Bisca; a design and construct company in North Yorkshire who have built high quality stairs for a number of private and commercial clients. Many of the structural forms are widely varied, sometimes entailing a 3D computer analysis. We collaborated and helped design the 2007 winner of the regional IstructE competition; The Helical stair with stainless steel plate stringers. The glass treads and balustrades are integral within the structure. Careful analysis and pre-construction in the workshop was undertaken in order to bring this unique stair to life. Scott Hughes Design has been fortunate to gain a vast array of experience in glass structures through working with Bisca.
