COMO The Treasury occupies the State Buildings, formerly the Old Treasury Buildings, a group of government offices built between 1875 and 1958 on the corner of St Georges Terrace and Barrack Street. Kerry Hill Architects led the restoration, and the hotel opened on 15 October 2015, turning former offices into guest rooms with updated layouts. It sits at 1 Cathedral Avenue in the heart of the city, about a 20-minute drive from Perth Airport. The hotel has three dining venues, Wildflower, Post and the Cape Arid Rooms, a heated indoor pool and a collection of art, and guests can borrow a bike to explore. We have not confirmed a formal star class, so the rating field is left at zero.
Location and getting around
The hotel stands at the western end of Barrack Street, so the Bell Tower, Elizabeth Quay and the river ferry jetties are a short walk toward the water. The historic city centre, Kings Park and the shopping streets are all within a bus ride or an easy cycle, and the hotel's bikes suit short trips.
For Fremantle you can take the train from the city station, and for Rottnest or the Swan River cruises you can walk to the jetties at Barrack Square. Parking is not described on the hotel page, so ask about it when you book.
The rooms and the feel
Because the building was once a set of government offices, the rooms vary in layout, and tall heritage windows, high ceilings and a restrained, art-led design are the hallmarks. Wildflower is described as a rooftop bar with a view of the Swan River, and the hotel also lists Post and the Cape Arid Rooms for dining, along with private dining, wine and beer masterclasses and wine luncheons. The wellness section includes a heated indoor pool, according to the hotel's description.
Who it suits and what to know: choose it for a special occasion, a honeymoon or a stay where architecture and atmosphere matter more than resort-style facilities. It is a good match for couples and for travellers who want a central base without a chain-hotel feel. Rates are at the top of the Perth range, so check what is included, and ask about breakfast, parking and room categories before you book. Because the building is historic, ask for a quiet room if you are a light sleeper.
