The design makes the most of the double-height heritage building, with saunas and contrast therapy suites cocooned in a central core on the ground level and practitioner rooms set above, joined by a steel stair. To the rear, a cosy lounge – complete with compression boots, reading materials and complimentary tea – offers a space for guests to unwind following a session. An adjoining pavilion behind the main building is a flexible area that can hold workshops, such as a recent breathwork class, or be activated for community and private events.Nimbus Co was founded nine years ago in Bondi, Sydney, by nutritionist Su Tuttle and Neil O’Sullivan, who left a corporate career in marketing to focus on mental health. In 2018, the first Melbourne location opened, in partnership with co-owner Eva Kiriakoff, a social-impact entrepreneur who also co-owns the new Fitzroy studio.
