Bespoke Staircases

Case Studies

Cummins UK, Daventry

This external spiral staircase really demonstrates that we can produce spiral fire escape staircases of any shape and size. This was one of a range of external escape stairs created for Cummins UK in Daventry, a leading manufacturer of diesel engines.

Working with SDC Builders, we designed and manufactured this large external spiral stair which had a security enclosure at the base, a rest landing, middle landing and a top landing that incorporated a section of straight treads right at the top.
