Perth begins at Point Zero, the marker from which Western Australia's road distances are measured. COMO The Treasury places its guests beside it. The 48-room hotel occupies part of the State Buildings at Cathedral Square. Here, former government offices share a city block with restaurants, bars, shops, and cultural spaces. Behind the civic facades, Kerry Hill's interiors are calm and spare. Tall windows, pale timber, handcrafted furniture, and travertine bathrooms soften rooms of unusual scale. The result is neither a conventional heritage hotel nor a sealed urban retreat. It belongs to the public life of central Perth, yet the bedrooms, pool, and wellness spaces remain notably composed.
Some rooms have roll-in bathrooms for guests with access needs. These layouts are available on request.
Large windows look over Cathedral Square, Stirling Gardens or the city. They can be opened, with natural tones and travertine tiles throughout the room. Furniture made for the hotel sits within its old State Buildings.
Standard layouts have a bath and separate shower in the en suite bathroom. The built-in wardrobe has a luggage rack, with tea and coffee facilities nearby. Electronic sheer blinds sit beside blackout blinds or curtains.

The State Buildings grew in stages between 1875 and 1958. Their architecture brings together Victorian Georgian, Victorian Second Empire, and Federation Free Classical styles. It reflects decades of government use rather than one neat period. Former offices included the Treasury, Lands and Titles departments, and the General Post Office. That layered history survives in varying ceiling heights, dormer windows, old trusses, and paneling. It also explains the different proportions of individual rooms.
Kerry Hill Architects led the restoration and hotel interiors. The team worked within the retained historic fabric instead of forcing every space into a standard plan. New elements are deliberately quiet. Natural light and generous empty space matter more than decoration. Modern screens, lighting, and bathrooms are integrated with little visual noise. Guests interested in architecture will find the irregularities rewarding. Travelers who prefer every room in a category to look identical should expect some variation within the old building.
The accommodation begins with 45-square-meter City Rooms. They face either the city or an internal courtyard. Heritage Rooms increase to 55 square meters and look toward Cathedral Square, Stirling Gardens, or the surrounding streets. At 75 square meters, Treasury Rooms provide a proper sitting area. Selected layouts also have space for an extra bed or cot. King and twin configurations are available across these main room categories. This makes them more flexible than their restrained design first suggests.
Balcony rooms deserve careful comparison. The 55-square-meter Heritage Balcony Rooms face east toward Cathedral Square. Their French doors lead either to a Juliet balcony or a walk-out balcony. The distinction changes how much usable outdoor space the room provides. Treasury Balcony Rooms are larger corner accommodations with a king bed and broad sitting area. Three sets of French doors open north and east. Neither category should be selected on the word balcony alone. Outlook, orientation, and balcony type are the details that shape the stay.
Suites start at 80 square meters. Studio Suites favor open living space and city landmarks. The Cabinet and Heritage Suites retain stronger traces of their former civic roles through wood details, dormer windows, or a truss ceiling. Treasury Suites add a separate sitting room and partial Swan River views. The 120-square-meter COMO Suite has separate living and sitting areas. Its outlook includes St Georges Terrace and Stirling Gardens. These layouts feel residential in scale, although they do not list kitchens or kitchenettes.
The clearest family arrangement is the 150-square-meter Family Suite. Two bedrooms connect through a private foyer. They can be set with two king beds or one king and two twins. The COMO Suite can also accommodate children with extra beds. Selected Treasury and balcony rooms accept a cot or additional bed. The heated indoor pool welcomes family use. Across Cathedral Square, the City of Perth Library gives younger guests an easy change of scene.
For longer visits, the advantages are room size, real sitting areas, and strong blackout treatments. Laundry service and in-room dining also help. Many restaurants are immediately accessible. The limitation is equally important: this is a hotel, not an apartment residence. Even the largest suites are designed around sleeping, bathing, working, and entertaining rather than self-catering. Guests who need a full kitchen should look beyond the generous floor plans. Those who prefer to dine out gain unusual variety without leaving the State Buildings.
Wildflower gives the hotel its most distinctive dining room. Positioned on the rooftop, it looks across the city and Swan River. Its menu follows the six-season cycle of the Noongar calendar. The idea is more than a label for local produce. Ingredients and dishes change with Western Australia's own environmental rhythm rather than a four-season European model. The setting is formal enough for an occasion. Yet the connection to place keeps the experience from feeling detached from Perth.
Post is the relaxed counterpart. It serves Italian-influenced cooking alongside dishes from the COMO Shambhala Kitchen. Cape Arid Rooms provide a quieter salon setting shaped by Western Australian art. Beyond the hotel's own venues, the same precinct contains Petition, Long Chim, Wine Merchant, Beer Corner, and Shop 1875. That separation is useful to understand. The hotel has a focused dining identity. The State Buildings supply a wider social scene that can carry a multi-night stay without repeated meals.
COMO Shambhala The Treasury occupies reworked spaces within the historic vaults. Four treatment rooms support massage, body, and facial therapies. A sauna and wellness lounge add time around a treatment. The 20-meter heated indoor pool is the visual center of the facility. Daylight filters into a long, quiet room that feels removed from the surrounding business district. It makes a proper swim possible rather than treating the pool as a decorative amenity.
A rooftop gym completes the core facilities. Together, the pool, gym, sauna, and treatment rooms give COMO The Treasury a strong wellness offer. Its compact 48-room scale might suggest less. The emphasis remains urban: there are no resort grounds or outdoor leisure pools. Instead, the wellness floor fits around meetings, city walks, long flights, and dinners. It provides a calm interval without asking guests to leave central Perth.
The address at 1 Cathedral Avenue is useful for both leisure and business. St Georges Terrace, Perth Town Hall, Stirling Gardens, and the Swan River edge are close at hand. Elizabeth Quay is an easy walk. So are central shopping streets and several cultural venues. Northbridge and Kings Park require a somewhat longer walk or a short ride. A car is unnecessary for many city days. Valet parking is available for travelers continuing through Western Australia.
Perth Airport is about 17 kilometers from the hotel. Taxi, private transfer, and car access are straightforward. Rail or bus services connect the airport with the central business district before a short final walk. Journey times vary with road conditions, so the distance is more useful than a fixed-minute promise. The hotel also works as a composed first or final stop around wider travels. Rottnest Island, the Swan Valley, Margaret River, and more distant parts of the state can follow.
COMO The Treasury is most convincing when its apparent contrasts are understood. The building is historic, but the rooms avoid period pastiche. The location is central and socially active. Yet only 48 accommodations sit above the precinct. Dining can move from a rooftop tasting menu to an informal neighborhood table. Meanwhile, the pool and spa create a quiet parallel world inside the old civic structure.
There are practical trade-offs. Views range from courtyard outlooks to city landmarks and partial river glimpses. No room should be assumed to have a broad Swan River panorama. Public restaurants and events bring life to the State Buildings. That may not suit someone seeking an isolated hideaway. For design-minded city travelers, food-focused weekends, business visits, and families who value genuine space, the combination is rare. Perth's historic center is experienced from within, with enough restraint and physical comfort to make the city feel manageable rather than merely busy.
Original government offices form the guest rooms, letting you stay within Perth's civic history while enjoying Kerry Hill's calm, contemporary interiors.
Wildflower's menu follows the six Noongar seasons, bringing Western Australian ingredients to your table with Swan River views from the rooftop.
Blackout blinds or curtains in the rooms let you shut out daylight when you want to rest after a long flight.

Yes. COMO The Treasury is one of Perth's strongest luxury hotels, especially if you want design, heritage, dining, and a central city location in one stay. It is housed inside the restored State Buildings in Cathedral Square, in the heart of Perth CBD. The hotel works well for couples, business travelers, food lovers, culture-focused guests, and travelers starting or ending a Western Australia trip. Expect calm rooms, polished service, strong restaurants, COMO Shambhala wellness, and easy access to the city.
COMO The Treasury is in Perth's historic State Buildings at 1 Cathedral Avenue, beside Cathedral Square and close to St Georges Terrace. The location places guests in the CBD, near government buildings, offices, restaurants, shopping, and cultural sights. It is a practical base for first-time Perth visitors because many central attractions are nearby. Elizabeth Quay, the Swan River, Perth Concert Hall, His Majesty's Theatre, and Northbridge are easy to reach by walk, taxi, or rideshare.
COMO The Treasury has 48 rooms and suites. The small room count helps the hotel feel quiet and personal, even though it sits in the middle of the city. Rooms are spacious by city-hotel standards and sit inside restored 19th-century government buildings. Layouts can vary because of the heritage structure, so choose your category carefully if balcony, view, fireplace, or extra space matters.
Book a Heritage Room if you want the signature COMO calm and a generous city room. Choose a Balcony Room if outdoor space and Cathedral Square atmosphere matter more. Suites are best for longer stays, special occasions, or guests who want a separate living area. Ask about views and original architectural details before booking. Some rooms feel more connected to the historic State Buildings, while others are better if you want quiet, light, and a simple city retreat.
The State Buildings are a restored group of 19th-century civic buildings in Perth. Their past uses included government offices, a post office, land titles offices, and treasury functions before the precinct was reimagined as a hotel, dining, retail, and cultural destination. This setting is central to the COMO The Treasury experience. Guests are not just booking a room; they are staying inside one of Perth's most important heritage precincts.
