About us.
Aatos Design is built on a close and considered approach to residential design - shaped through careful thinking, clear process, and a deep understanding of everyday liveability.
About us.
Aatos Design was established in Sydney’s Northern Beaches, shaped by a desire to craft a highly personal, design-led residential experience.
The studio has since evolved to work across both New Zealand and Australia, delivering projects on both sides of the Tasman.
Now based between Matakana and Ponsonby, Aatos is embedded in the Auckland region while continuing to deliver projects across Sydney.
This dual presence allows us to maintain longstanding client and supplier relationships in Australia while building a considered and growing body of work in New Zealand.
Our work centres on whole-home design through interior architecture - shaping homes from the inside out. At its core, Aatos remains a close, highly considered practice - focused on creating and transforming thoughtful homes through direct collaboration and a deeply involved design process.
Ideology & Vision.
Our design language speaks of pragmatism, consideration, and authenticity.
We believe well-resolved home environments have a direct impact on how we live, shaping the way spaces are experienced each day. Our work balances creative thinking with technical clarity to create homes where space, form, and materiality work together as a cohesive whole.
While our approach remains consistent across all projects, each response is carefully tailored to both client and context—resulting in environments that feel grounded, functional, and enduring.
Guided by nature, innovation, and the emotive sense of place, we create homes that support a clear and lasting way of living.
Team.

Brad Donelley | Project Director & Designer
Brad brings over 20 years of experience across property, design, and project delivery, with a deep understanding of how buildings are planned, constructed, and maintained.
With a background spanning large-scale commercial projects and residential construction, he brings a strong foundation in building design, technical documentation, and on-site delivery. Working across all stages of a project, Brad ensures clarity, coordination, and buildability from early planning through to completion.
Detailed in his approach and commercially minded, he leads the delivery of Aatos projects end-to-end - managing cost, programme, and procurement while maintaining the integrity of the design. His role is central to translating design intent into clear, buildable, and well-executed outcomes.
