From bubble-like bulges amid the arches of London’s iconic Old Billingsgate to a 15-meter-tall red droplet frozen in the center of a disused swimming pool in Aberdeen, Steve Messam explores scale, form, and our experiences of the built environment in large-scale installations.

Messam is known for his large-scale inflatable works that reinterpret architecture and explore human influence over the landscape. Often, he fills apertures like arcades or underpasses with forms that balloon and billow, drawing attention to structural forms while considering their fundamental function as places to enter or move through.

In “Accommodation:Occupation,” Messam delves into the history of 19th-century infrastructure in the U.K. through an exploration of what are known as accommodation and occupation bridges—railroad crossings designed for rural areas that provided a tunnel beneath, so that farmers could still access their land on the other side of the tracks. Some of these historic bridges still exist, often on private land, such as two in County Durham along the former route of the Stockton & Darlington Railway.

For “Below,” which Messam situated under a bridge in Tianfu Art Park in Chengdu, China, the site’s use as a thoroughfare is retained by creating two symmetric forms with a gap between them, which people can walk through while immersing themselves in the installation.

Whether popcorn-like, spiked, bubbling, or cascading, Messam’s playful interventions prompt us to view our surroundings with renewed attention. Explore even more on the artist’s website and Instagram.
