EeStairs + Artillery Architecture & Interior Design

EeStairs partnered with Artillery Architecture to develop the feature staircase scheme with a focus on optimising the staircase geometry and specification. 3D visualizations were used to explore multiple staircase configuration options.

Unusually, the staircase features thirty two rises without any rest landings. This staircase geometry ensures that the beauty of the helix is not interrupted by horizontal landings. The staircase features a fabricated mild steel carcass manufactured in EeStairs’ workshops and delivered to site in seven large components which were assembled and welded onsite. The inner balustrade and soffit are formed using handmade cast GRG panels skimmed and painted onsite for a seamless finish.
