A unique and extraordinary spiral staircase has been constructed in the KF Aerospace Centre for Excellence in Kelowna, BC, Canada. The staircase consists of a timber-concrete composite system (TCC) and spans a length of approximately 70 ft and a height of approximately 23 ft without intermediate supports.
The Moongate residence, located in Sedona, Arizona, USA, was exceptionally designed by the Scottsdale-based architecture and planning studio of SWABACK.
China’s increasing economic development has led to the construction of many large commercial complexes with an increasing demand for escalators with great heights and large spans, without intermediate supports.
In 2017, VIC OBDAM was commissioned by BAM to fully design the Kasbank project (total weight about 368.17 t) in Amsterdam. This project included a free-standing steel spiral staircase.
In late 2018, Naikoon Contracting Ltd. announced the location of their new global headquarters in Vancouver, BC, with a grand opening in spring 2019. The new office is centered around a stunning cross-laminated timber (CLT) staircase which utilizes a profound gluing technology developed by Timber Structures 3.0 (TS3). This marks the first time TS3 has been used in North America.
The modular structure of the school will only remain at the present location for eight years. After this period, 36 timber modules, including the screw foundations, will be removed entirely and reconstructed at another location. Therefore, a completely new configuration of the floors and the ground plan design will be possible. The simple yet functional structure includes the architectural highlight of a front-facing flight of stairs constructed with timber truss girders.
