Denton Associates commissioned LSJ Engineering to design a feature staircase for an office fit out for Xero in Kings Cross.
- Client: Denton Associates
- Structural detail by: Mark Ebbs
The challenge on this job was that the stair ran from 7th to 8th floor levels, and the only access was via a 2.5m long lift. This meant that all the stair stringer and balustrade sections had to be less than 2.5m in length! They still required powder coating off site.
Our team designed the stringers to have neat joints. This allowed them to be bolted together once we got them to the correct level. It also ensured the stingers are as strong as if they were on one piece. The half landing support posts formed an ‘X’ to reflect the end client’s logo.
The perforated balustrade panels were bespoke, punched to form neat borders around each balustrade, while the copper handrails were fitted by others.
LSJ also undertook the demolition works to form the stair void opening in the 8th floor slab. We subcontracted to Evolution Enabling of Rayleigh, who installed a crash deck, saw cut and removed the slab, which was equally as challenging as the stair install.
