DKO Architecture has promoted Sonny Oh and Lizzie Rix to Director and elevated Aaron Bettio-Sandlant to Senior Associate across its Sydney studio, in the practice’s latest round of senior leadership appointments.

Sonny Oh’s promotion to Director recognises a body of work spanning projects of varying scales, alongside a contribution to DKO’s studio culture that the practice identifies as equally central to this recognition. Oh has developed a talent for uncovering opportunities early in the design process — the kind of thinking that allows complex challenges to be distilled into clear ideas and concepts, and which DKO describes as foundational to great architecture. While his approach consistently pushes projects further, it does so while remaining true to the simple, powerful concepts at the core of each brief — a discipline that, across varying project conditions, defines his design contribution. He has equally established himself as a generous studio mentor, investing deliberately in the growth of those around him. His promotion, DKO notes, recognises not only his design leadership but the lasting impact he has made on the culture of the studio.

Lizzie Rix joined DKO in 2021 and has, over five years, built a reputation defined by technical strength and a consistent commitment to seeing projects through to completion. This focus has positioned her at the centre of some of the studio’s more demanding work — projects where precise construction detailing and the realities of large-scale delivery require steady, rigorous attention across every phase. Rix has built strong, trusted relationships with consultants and builders throughout this work, and her clear communication style has earned her significant respect across the industry. Discipline, confidence and an unwavering commitment to quality are the qualities DKO highlights in marking her promotion to Director.

Aaron Bettio-Sandlant’s elevation to Senior Associate acknowledges a reputation built through small to medium density residential projects, with particular strength across the planning and stakeholder engagement phases — stages where his ability to anticipate challenges, unlock project potential early and build trusted client relationships has had consistent impact. His contribution extends well beyond the projects he directly oversees: Bettio-Sandlant is identified by DKO as a valued studio mentor, particularly for colleagues navigating their architectural registration, generous with his time and invested in developing those around him. DKO characterises him as someone who brings a collaborative spirit — and, as the practice notes, plenty of personality — to the studio.
