What Alexandra Buchanan Architecture does
Alexandra Buchanan Architecture is a boutique residential architecture studio founded in 2011 by Alexandra Buchanan, operating studios in Brisbane (Fortitude Valley) and Melbourne (Carlton) with a by-appointment office in Daylesford. The practice creates highly resolved private residences across Australia and internationally, with a documented project portfolio spanning urban infill, heritage Queenslander renovations, laneway houses, rural homestead restorations, and Passivhaus-certified new builds. Core capabilities include architecture, interior design, and landscape architecture delivered as an integrated service. Technical specializations include Passivhaus design principles, heritage Queenslander renovation and relocation, courtyard-centric planning, subtropical home design, and rural homestead restoration combining heritage sensitivity with contemporary additions. Notable projects include Kent House (2024, awarded 2025 HIA Kitchen of the Year and Dezeen longlisted), Binnum Homestead (2025 AIA Building of the Year Darling Downs), Taringa Passivhaus (under construction), and Merri Creek House (ArchDaily nominated).
The business operates as a privately held, founder-owned practice (legal entity Alexandra Buchanan Pty Ltd) with no external investment, no parent company, and no subsidiaries. Revenue is generated through bespoke architectural commissions on a project-fee basis, with the firm undertaking only a 'select number of commissions each year' to preserve depth of focus. The go-to-market is selective and enquiry-based: potential clients submit enquiries via the website, and projects are evaluated on alignment, scope, and ambition. The client base is affluent private residential, served through direct enquiry, word-of-mouth referrals, and visibility generated by earned media coverage in Dezeen, AIA, HIA, Wall Street Journal, Architecture Australia, and The Design Files. Pricing is not publicly disclosed and is quote-based per project, with typical multi-year contract duration across design and construction phases. The firm has been carbon neutral certified since 2021 and currently employs approximately 10 named professionals across architecture, interior design, and technical roles.
