Why a Railway Arch?
Arches offer ceiling heights of 3–8m at the peak — enough for rope climbs, Olympic lifting, and climbing walls. The structural strength supports wall-mounted rigs, pull-up bars, and heavy equipment without reinforcement. The industrial aesthetic is aspirational for fitness brands, and the enclosed space contains noise from dropped weights and loud music. Lower rents per square foot compared to purpose-built gym space improve margins in a competitive market.
