A monumental black V stands between the New Exhibition Centre and the towns of Rho and Pero, a modern gateway to the outskirts of Milan. Two NH Hotel towers, designed by architect Dominique Perrault and opened in 2009, are presented as a facility in constant motion, generated by tilting the mirror surface of the stoneware-glass black colour coating. The entire complex significantly benchmarks the “architecture park” of Fieramilano, which also includes the exhibition centre by Massimiliano Fuksas. Like the latter, Perrault has surrounded his creation with five large ponds made from Watercube. Particular attention was paid to the design of the installation managing to place the hydraulic components in the small gap above the ceilings. To complete the work, two walls inclined by -5° as compared to the vertical plane have been fitted with a Waterwall acting as a vertical connection between the two golden structures inserted between the towers.
