The advanced architecture of Mandarin Oriental, Las Vegas’ exterior was designed by the award-winning firm Kohn Pedersen Fox. One of the key aims when designing Mandarin Oriental, Las Vegas was to achieve a building design that was as durable and energy efficient as possible within the taxing Las Vegas climate. Based atop a podium made of zinc, titanium, granite and limestone, the building rises vertically into a façade that draws inspiration from traditional Chinese motifs. Interiors have been designed by Adam D. Tihany with the infusion of contemporary elegance and delicate artful Asian influences.
