What Rob Mills Architecture And Interiors does

Rob Mills Architecture & Interiors, operating through Trade Winds Holdings Pty Ltd (ACN 112 806 185), is an Australian luxury residential architecture and interior design practice founded in the early 1990s and headquartered at 10 Grattan Street, Prahran, Melbourne. The firm delivers an integrated four-part service model covering land identification and acquisition, full architectural design, interior design, and strategic management (contract administration) under one roof, with each engagement delivered as a bespoke, fixed-price contract coordinated with selected builders. Its client base consists exclusively of high-net-worth private individuals and families commissioning primary residences, holiday homes, heritage renovations, coastal residences, country homesteads, and boutique apartment developments across Australia and internationally.

The practice operates from studios in Melbourne, Sydney, Perth, Brisbane, Byron Bay, and Milan, supported by region-specific landing pages spanning Australia, the United States, the Bahamas, St Barths, Geneva, New Zealand, the United Kingdom, France, Spain, Italy, Singapore, Hong Kong, the United Arab Emirates, and Brazil. Technical delivery is anchored in BIM and Revit-based design processes, with a stated requirement that all design hires be proficient in these tools; additional in-house capabilities include visualisation and sustainable design delivery, with the firm institutionalising 7-star energy-rated homes, off-grid architecture, and carbon-neutral home design as standard offerings above Australia's 6-star baseline.

Revenue is generated through professional services fees on a quote-based, project-by-project basis, with pricing not publicly disclosed. The go-to-market model is direct field sales: clients engage via studio offices, personal referrals, and the practice's award-winning portfolio and social channels (notably Instagram and a dedicated Films section on its website). Revenue streams comprise architecture services, interior design services, and strategic management/contract administration, all delivered under fixed-price contracts. The firm has not raised external funding, operates without a parent company, and has no public listing.
