An off-white fibreglass staircase with red-hued steps is the focal point of this clothing store in Shanghai. It was designed by local studio AIM Architecture, taking inspiration from a suburban skate bowl.
Upon entering the store, visitors are greeted by the 4.2-metre-tall structure that wraps around concrete columns much like the form of a children's slide, leading customers on a red, winding path through the store.
This hostel building for girls by Zero Energy Design Lab has a concrete structure with a perforated facade characterised by angular meandering lines that frame an external staircase.
The staircase runs along the exterior of the hostel, appearing to bisect the building diagonally. At its landings, the staircase is adjoined to a number of external breakout spaces which the architects hoped would encourage socialising.
Designed by Danish architecture firm BIG, this viewing tower is formed wholly from a double-helix spiralling staircase.
The 25-metre-tower widens as it nears the top to form a viewing platform providing 360-degree views across the marshlands that give the structure its name. The platform is accessed by a 146-step climb – or via an elevator located at the core of the tower.
Dutch architecture firm OMA overhauled a US Postal Service building, transforming it into a multi-use cultural and retail venue connected by sculptural staircases.
One of the staircases located within POST Houston has a Piranesian quality, comprising two sets of mirrored concrete steps supported by a green under-structure. The two sets of stairs zigzag and dogleg throughout the atrium to create two X shapes when viewed from the front.
Canadian architecture studio Saia Barbarese Topouzanov added colourful spiral staircases to housing units in Montreal's Saint-Michael neighbourhood.
The spiral staircases were added to a brutalist-style housing complex built in the 1970s, providing balconies for the apartments. They were pigmented in seven different tones from pale yellow to brick red.
