COMO The Treasury

Stone, Arches, and the Weight of Western Australian History

There is a particular quality of arrival at Perth's former State Buildings complex on Cathedral Avenue: the neo-Renaissance facades rise with the self-assurance of a colonial institution that expected to last centuries, and, architecturally speaking, it has. The cantilevered balconies, copper-trimmed Victorian rooflines, and dormer windows were built to project permanence, and the restoration that brought COMO Hotels and Resorts into the precinct has preserved exactly that character. What changed is the interior proposition. Where land titles officers once processed deeds beneath those soaring arches, guests now move through a hotel that treats the bones of the building as the primary design statement.

The restoration methodology here is worth understanding as an approach, not just a result. Internal walls were retained in their original configuration rather than reconfigured for efficiency, which means the 48 rooms across the complex are each genuinely distinct in size, footprint, and aspect. This is how heritage buildings are handled when the architecture is treated as an asset rather than a constraint. Properties that pursue this approach, among them Claridge's in London and Gleneagles in Auchterarder, accept the operational complexity of irregular room configurations in exchange for authenticity that no new-build can replicate. COMO The Treasury takes that same position on the other side of the world, at a price point from around AU$576 per night.

Architect Kerry Hill and the Pale Earth Tone Interiors

The interiors were designed by Kerry Hill, the Singapore-based architect whose work across the Pacific Rim consistently favoured calm materiality over decorative spectacle. Hill's signature is restraint with precision: pale earth tones, clean geometry, and a deliberate suppression of surface noise that allows structural features to read clearly. At COMO The Treasury, that approach means the truss ceilings, oversized opening windows, and custom bronze-cast mirrors by artist David Brazier become focal points precisely because the walls around them carry no competing artwork. The Cape Arid Rooms represent a considered exception: botanical illustrations from the Cape Arid Collection by Philippa and Alex Nikulinsky, inspired by their traverse of Cape Arid National Park, hang in those rooms as place-specific objects rather than decorative filler. They are available to purchase as prints or in book form, which gives them a weight that generic hotel art does not carry.

Bathrooms across the property follow a consistent specification: heated travertine stone flooring, German Kaldewei Duo freestanding bathtubs, walk-in showers, and COMO Shambhala products. The minibar reads like a considered edit of Western Australian provenance: Riedel glassware, Limeburners whisky from the Great Southern region, Vasse Felix wines from Margaret River, and Sue Lewis chocolates made in Perth. At properties in this tier, including Lime Wood in Lyndhurst and Estelle Manor in North Leigh, the minibar is frequently where the regional sourcing story gets told most directly. Here it does the same work.

The Fourth Floor and the Restaurant Question

Perth's dining scene has matured considerably over the past decade, and Wildflower, positioned on the hotel's fourth floor, is widely regarded as among the city's serious restaurant propositions. The terrace looks across Swan River, and the views carry enough weight that the space functions as a destination in its own right beyond the dining room. A sundowner on that terrace during the long Western Australian summer evenings is one of the more direct arguments for choosing this address over alternatives like Crown Towers Perth, which operates at a different scale and energy. The ground-level Post restaurant works the French-inspired register, and both draw from Western Australia's agricultural output, including avocado, mandarin, and passionfruit, which feature across menus seasonally.

The broader precinct adds further depth. The State Buildings complex includes Long Chim, Petition, a Wine Merchant, Beer Corner, Pooles Temple, and Telegram Coffee, among others. Guests can move through a range of formats within the same architectural envelope without stepping onto the street. For visitors working through our full Perth restaurants guide, this concentration inside a single precinct is a practical consideration worth weighing alongside the hotel's room rate.

Wellness, Safe Doors, and the COMO Shambhala Urban Escape

The spa operation here sits within the COMO Shambhala brand, which operates across COMO properties globally and brings a consistent holistic treatment philosophy to each address. What distinguishes the Perth iteration physically is the retained safe doors from the Treasury's original secure vaults, now serving as a dramatic architectural counterpoint to the soft treatment-room lighting. It is the kind of detail that emerges from a serious restoration brief rather than a cosmetic one, and it places the spa in a different conversation from purpose-built wellness facilities at newer hotels. The fitness centre and an indoor swimming pool complete the wellness infrastructure.

Perth as Context: The City of Light

Perth's geographic isolation is well documented: it sits roughly 2,700 kilometres from the next major Australian city by road, which historically created a certain scepticism about whether the city could sustain a hotel at this register. That scepticism has eroded. The La Liste Leading Hotels ranking awarded COMO The Treasury 94.5 points in 2026, placing it in a tier alongside properties from cities with far more established luxury hotel markets. The Google review score of 4.7 across 584 reviews provides a secondary signal of consistent delivery. Perth's nickname, the City of Light, dates to 1962 when residents illuminated the city as American astronaut John Glenn passed overhead during his orbital flight: it is a piece of local identity worth knowing, and it speaks to a city with a habit of signalling its presence to the wider world. Valet parking is available for hotel guests, with fees applicable.

For those building a broader Western Australian itinerary, our full Perth hotels guide covers the competitive set in detail, and our full Perth experiences guide maps the cultural and outdoor options across the region. Comparison with heritage-adaptive hotel projects in other markets, including Muir, A Luxury Collection Hotel in Halifax, 100 Princes Street in Edinburgh, and The Newt in Bruton, confirms that the adaptive reuse approach COMO employed here is not unique to Perth but is executed with particular fidelity to the original structure. Further afield, those interested in how luxury hotel groups approach historic buildings in entirely different urban contexts might also consider Aman Venice or Aman New York as instructive comparisons. For British counterparts working in the heritage register, Abbots Grange Manor House in Broadway, Amberley Castle, Ashdown Park Hotel in Forest Row, and Alexander House in Turners Hill each demonstrate how differently the same preservation mandate can land. At the design-led independent end, Artist Residence Brighton, Artist Residence Bristol, Artist Residence Cornwall, and Artist Residence Oxfordshire show what happens when artistic sensibility rather than institutional scale leads the brief. Rural Scottish alternatives including Ballintaggart Farm in Pitlochry and The Fifth Avenue Hotel in New York City round out the comparative picture for travellers calibrating where COMO The Treasury sits in a global portfolio.

Frequently Asked Questions

What is the vibe at COMO The Treasury?

The atmosphere is calm and architecturally anchored: high ceilings, pale stone, and the preserved fabric of a 19th-century government complex create a sense of weight and quiet that contrasts sharply with the glass-and-steel Perth CBD immediately outside. The arrival lounge replaces the standard reception desk, which sets the pace from the moment guests enter. La Liste awarded the property 94.5 points in 2026, and the Google score of 4.7 from 584 reviews reflects consistent delivery on that register. Room rates start from around AU$576.

What is the leading suite at COMO The Treasury?

Because the building's original internal walls were retained during restoration, every room and suite carries a distinct footprint. The upper-tier suites include features such as working fireplaces, Swan River views, and bathrooms described as bordering on palatial, with heated travertine floors and Kaldewei freestanding bathtubs. The La Liste 94.5-point ranking (2026) provides the clearest external calibration of where the property sits in the global luxury tier. Specific suite pricing is leading confirmed directly with the property.

Why do people choose to stay at COMO The Treasury?

The combination of a restored heritage building, architect Kerry Hill's interior design, and the Wildflower restaurant on the fourth floor drives the majority of the guest rationale. For visitors to Perth, the precinct also provides access to a dense cluster of dining and drinking venues within the same State Buildings complex. The 94.5-point La Liste score (2026) and a Google rating of 4.7 from 584 reviews confirm the property holds its position among Perth's small tier of credible luxury hotel options. See our full Perth hotels guide for competitive context.

How far ahead should I plan for COMO The Treasury?

At 48 rooms, the property operates at a constrained capacity, and demand from both leisure and corporate travellers tracking a 94.5 La Liste score can tighten availability during Perth's peak periods, generally October through April when the climate is warmest. Booking six to eight weeks ahead is a reasonable baseline for standard rooms; suites and high-demand periods warrant earlier planning. Check directly with the property via their official website for current availability and rate confirmation.

What makes COMO The Treasury's minibar worth paying attention to?

The minibar is stocked with a curated selection of Western Australian producers: Limeburners whisky from the Great Southern, Vasse Felix wines from Margaret River, Sue Lewis chocolates made in Perth, and Riedel glassware. Rather than generic international brands, it functions as a concentrated edit of the region's premium food and drink output, which gives guests a practical entry point into Western Australia's producer landscape without leaving the room. The Cape Arid botanical prints in the Cape Arid Rooms work similarly as place-specific objects with a direct connection to WA's natural environment.
