Kreis Grennan Architecture believes that great design is a platform that can lift people’s spirits and encourage them to appreciate beauty in everyday life. The practice formed in 2015 as a creative collaboration between architect and licensed builder, Christian Grennan, and property developer and project manager, Chris Kreis. With these complementary skills and ranges of experience, KGA provides

the best possible integrated services in architecture, urban design, project management and property development. Working across single residential, multi-residential and commercial projects, KGA’s process is always collaborative — listening carefully to clients, consultants and craftspeople, asking questions, thinking critically and providing a transparent decision-making process.
