STM Property Group is a Sydney-based property development and investment business with a long-term focus on owning and operating high-quality residential and mixed-use assets.

Founded in 2006, STM specialises in design-led developments across Sydney’s Eastern Suburbs, partnering with leading architects, designers, and consultants to deliver projects that stand the test of time — commercially and architecturally.

Unlike traditional developers, STM retains the majority of its developments, building a high-performing rental portfolio managed by our in-house property team. This long-term ownership mindset drives better decision-making, higher build quality, and a strong sense of accountability throughout the development lifecycle.

Alongside our build-to-hold strategy, STM selectively delivers build-to-sell projects where it aligns with market conditions and project fundamentals.
