Restoring Heritage with Raw Elegance

Arched openings and rugged brickwork bring a touch of ancient Rome to Alchemy Saunas, a wellness haven crafted by Rezen in Fremantle, Australia. With a thoughtful nod to the ancient bathhouse style, it is nestled within the Royal George Hotel’s original 1903 stables and cellar. The center undergoes an innovative transformation while retaining its historical roots.

Studio director Rhys Bowring emphasized the pragmatic, unembellished design approach, stating, “The material palette was intentionally kept recessive to highlight the existing red brick and Tamala limestone.” This focus on raw materiality aligns with the space’s utilitarian past and classic aesthetics.

Design and Material Synergy

Entering through the hotel’s basement, the spa integrates utilitarian steel and tile with the organic textures of its historic setting. A central steel staircase links the entry to changing rooms enveloped by contrasting stainless steel and rough limestone surfaces, reflecting an ancient bathing style.

Saunas, discreetly housed in the western section, employ glazed exteriors and timber-lined interiors, maintaining a balance between modern functionality and traditional ambiance that mirrors historic bathing spaces.

Roman Bathhouse Aesthetic: Innovative Spatial Layout

Rezen navigated existing spatial constraints by aligning new installations with pre-approved project locales. The basement features two distinct pools, an ice pool and a warm magnesium pool, within the soaring double-height stable area. Both are illuminated by grand arched windows, creating a harmonious blend of natural light and material texture that exemplifies the ancient bathing tradition.

Concrete seating encircles these bathing spaces, providing structural reinforcement to the historic brick. New openings utilized exposed steel lintels, underscores a minimalist aesthetic while honoring the site’s architectural legacy and enhancing its interior transformation.

Creating Diverse Bathing Environments

Reflecting on the design, Bowring notes the placement of saunas and washrooms in areas with limited height, while generously spacious communal baths enjoy full daylight and openness, embracing traditional spa elements. This thoughtful arrangement caters to varied experiences from secluded, intimate spaces to lively, sunlit pools.
