Elliptical Spiral Staircase

City of London

Elliptical Spiral Staircase

This sculpted elliptical spiral staircase sweeps elegantly between floors with no intermediate support. The stair is constructed from stone clad insitu concrete and has a thin tapered profile. The geometry creates a structurally complex interaction of internal forces which were reinforced for. The dynamic performance was also verified by the structural analysis model.

The project was awarded the RIBA London Award 2017

*This project was undertaken whilst at a previous practice with significant involvement from a Director at SD Structures.
