What k20 Architecture does
k20 Architecture is a privately held, founder-led architecture practice established in 2001 in South Melbourne, Victoria, by Theodore Kerlidis and Anthony Uahwatanasakul. The firm operates as a multi-award-winning public projects specialist with panel appointments across Local, State, and Federal government tiers, serving councils, educational institutions (Deakin University, Monash University, Our Lady Help of Christians, Southmoor Primary), healthcare providers (Royal Children's Hospital, St John of God), sporting clubs and associations (Port Melbourne Football Club, Ballarat Red Devils, Knox Regional Netball Centre), and heritage authorities (Heritage Victoria, Heritage Tasmania). It maintains a secondary regional office in Apollo Bay, Victoria.
The firm applies a proprietary 'Eco-Centric Architecture' methodology that integrates design excellence, sustainability, and performance outcomes — including economic, environmental, and social dimensions — across the full project lifecycle from pre-design through to handover. It is ISO 9001:2015 certified in Quality Management, holds A+ membership of the Australian Institute of Architects, operates as a carbon-neutral business, and produces post-occupancy evaluations through its 'People in our Architecture' process. Notable technical components include passive environmental design, thermally broken double-glazing developed with Pilkington, masonry heat exchange labyrinths, and earth pipe heat exchange systems, alongside modular/prefabricated construction techniques for time-critical educational facilities.
Revenue is generated through professional services fees for architecture and project management commissions, primarily negotiated on a project basis via government panel appointments and direct institutional commissions. Work spans nine service categories — community, sports, education, healthcare, childcare, heritage, civic, residential, and architectural competitions. Differentiators include a documented cost variance of less than 2% between cost plan A and D, registered heritage practitioner status, NatHERS 9.1-star-rated residential outcomes (Trinity Apartments), 60% electricity reduction versus the replaced facility (Hindmarsh Shire Council Offices), and 50+ industry awards accumulated between 2008 and 2024.

- ClarkeHopkinsClarke: Large Australian architecture practice with deep public-sector exposure across education, civic, transport and community infrastructure. Overlaps directly with k20 on government panel work and education/community sector delivery, though operating at significantly larger scale.
- Fender Katsalidis: Established Melbourne architecture practice with significant cultural, civic, residential and heritage work, including adaptive reuse. Comparable on Victorian operating base, civic and heritage sector exposure, and reputation for award-winning public architecture.
- Kerstin Thompson Architects: Melbourne-based architecture practice of similar size with a comparable focus on sustainable, site-responsive public and residential projects in Victoria. Both firms share a small-team model, sustainability-led methodology, and a strong awards profile, making them the closest direct comparables in the Victorian sustainable-architecture niche.
- Jackson Clements Burrows (JCB): Multi-award-winning Melbourne architecture practice with comparable civic, education, sports and residential portfolios. Similar in size, sector mix, and awards-driven positioning, and a frequent co-competitor on Victorian public tenders.
- Breathe Architecture: Australian architecture studio specialising in sustainable, community-focused and social-housing projects, including multi-residential work such as The Commons and Nightingale. Directly comparable to k20 on eco-centric design philosophy, social/sustainability housing exposure, and Victorian operating geography.
- Architectus: Australian architecture firm with strong public-sector, education and civic portfolios across multiple states. Comparable to k20 in client segment (councils, universities, public agencies) and in pursuit of sustainability-led design, though materially larger and more geographically diversified.

- Cox Architecture: One of Australia's largest and most awarded architecture practices, with broad public-sector, education, civic, sports and cultural portfolios. A direct competitor on Victorian government panels and design competitions, but operating at materially larger scale across multiple states and sectors.
