COMO The Treasury: Kerry Hill designed 19th-century State Buildings sanctuary in Perth with rooftop Wildflower and COMO Shambhala Spa
Occupying the impeccably restored collection of three 19th-century State Buildings (the Lands, Titles, and Treasury buildings) in the historic heart of Perth, Western Australia, COMO The Treasury opened in 2015 as an architectural masterpiece. Master-designed by legendary architect Kerry Hill, the 48-room luxury haven preserves historic dormer windows, original jarrah timber floorboards, and high vaulted ceilings. Featuring the critically acclaimed rooftop restaurant Wildflower (celebrated for indigenous six-season Western Australian gastronomy), the Italian osteria Post, a heated indoor swimming pool beneath a soaring glass roof, and the holistic COMO Shambhala Urban Escape, this property is Australia’s premier luxury heritage hotel.
Arrival introduces travelers to unvarnished 19th-century Australian architectural grandeur: personal hosts greet guests beneath grand colonnades beside the restored clock tower with chilled Margaret River sparkling wine and cold herbal towels. Day-one logistics focus on coordinating bespoke Perth cultural, wine, and coastal pursuits: exploring the State Buildings’ artisan chocolate shops, bookstores, and wine bars on-site, strolling through Kings Park and Botanic Garden (10 minutes away), visiting Cottesloe Beach or taking ferry trips to Rottnest Island to see quokkas, swimming in the heated indoor pool beneath the glass conservatory, indulging in botanical therapies at COMO Shambhala Urban Escape, enjoying aperitivo at the Cape Arid Rooms, and reserving dinner at Wildflower.
Hotel living balances heritage elegance with serene Australian wellness: the COMO Shambhala Urban Escape features four private treatment suites, steam rooms, the indoor pool, and therapies utilizing organic botanicals, Western Australian clay, and Asian holistic techniques. Dining is a celebrated Australian summit: indigenous six-season Western Australian fine dining at Wildflower on the rooftop (featuring marron, Geraldton kingfish, kangaroo, and Margaret River Grand Crus), authentic Italian regional dining at Post, and pastries in the Cape Arid Rooms.
Accommodations comprise 48 rooms and luxury suites designed by Kerry Hill ranging from 55 to 120 square metres. Each residence features custom bronze and dark timber furnishings, soaring ceilings, views of the Swan River or Stirling Gardens, plush king beds, and marble bathrooms with freestanding Kaldewei soaking tubs, heated floors, and COMO Shambhala amenities.
Heritage purists, culinary connoisseurs, and luxury travelers seeking Kerry Hill architectural perfection, Wildflower rooftop dining, and COMO Shambhala wellness in Perth should book COMO The Treasury without hesitation. Travelers seeking generic airport business towers should look elsewhere. Grounded review consensus confirms legendary standing with a 4.9 out of 5 on Tripadvisor across 1,600 reviews and a 4.9 out of 5 on Google across 2,100 reviews.
