Before opening shop in Toronto in 2011, then selling online-only, Khai Foo spent 15 years honing high-performance concrete into fireplaces and pits. Hand-cast to spec, with multiple fuel and finish options, his sculptural fire features are adaptable to any contemporary space, indoors or out. Paloform has models that range from thick concrete bowls to slim-profiled squares of Corten to rectilinear tables whose folded aluminum sides intrigue the eye with shadow play.
