What Zai does

ZAI Pty Ltd is a Melbourne-headquartered architecture, urban design, and planning firm founded in 1951 by Polish engineer Michael Zakrewski as a multi-disciplinary Building & Engineering practice in Durban, South Africa. The firm operates across Australia, Southern Africa, Central Africa, Mozambique, Malaysia, Iran, and the USA, delivering projects in apartment buildings, hotels, residential multi-unit developments, commercial and retail facilities, convention and exhibition centres, healthcare facilities, and district-scale master planning.

Its service portfolio spans the full architectural lifecycle — concept design, master planning, construction documentation, 3D modelling and visualisation, contract administration, and project management — underpinned by an Ecologically Sustainable Design (ESD) philosophy and Green Building Council Australia membership held since 2008. Notable completed projects include the 80% extension to the Durban ICC Arena, the Polokwane International Convention Centre, a 240,000 sq m mixed-use development in Tehran, and a 300-suite 5-star hotel in Iran. The firm also participates in international design competitions (2010 FIFA World Cup Soccer Stadium consortium, 2011 Chinese civic and convention competitions in Ordos and Korla).

Commercially, ZAI generates revenue through project-based professional services fees on major commercial and public-sector commissions, with engagement typically driven by direct enterprise field sales to developers, government bodies, healthcare providers, and corporate entities. Distribution is direct, with no intermediary or reseller channels. Delivery in international markets is enabled through a network of regional strategic partners (Matrix Project Managers in South Africa, Emco in Iran, PDM Asia Pacific in Malaysia, Ocean Architects in South Africa), and the firm operates a Southern African regional entity under the trade name MI5 Architecture + Urban Design. No marketing channels, digital acquisition mechanisms, or pricing transparency are documented; engagement economics are negotiated on a per-project basis.
