Elliptical Spiral Staircase
City of London
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.
