Often seen as only an industrial product, concrete has been transformed into a luxurious material by Walker Zanger,blending interior design with contemporary architecture in the new Kaza collection of 3: Lantern,Saturn and Vortex. They span the stylistic spectrum, from the angular geometry to the soft curves -“Lantern’s” ribbed-yet-soft texture, drawing inspiration from George Nelson’s iconic 1947 lantern-lamps. “Saturn” imbues a 1960s-mod feel with its soft-cream surface, and “Vortex” uses elongated hexagons to create a sci-fi feeling of being pulled into a tractor beam.
