Our experience and range of design skills gained all over the world allows us to craft distinctive spaces to live, work and play.

KGA's creative output is driven by a collaboration between architect & builder Christian Grennan, and project manager & property developer Chris Kreis. 

Christian Grennan

Design Director
Principal Architect

Born into a family of makers, Christian has worked as an architect for more than 25 years both locally and internationally on multi-residential and mixed-use projects. He takes great pleasure in learning from all those around him — clients, professionals, tradespeople and the team at KGA — enjoying the process of crafting unique spatial solutions for people to enjoy.

Christian currently lectures in design and construction at UNSW. His interests outside of architecture and design include woodwork, metalwork, contemporary art and film, nature, poetry and landscape design.

Chris loves working with people and property, a joy that has developed over 25 years in the architecture and property development industries. Managing development projects, he enjoys the delivery of unexpected design solutions to clients to achieve a better outcome. He applies both precision and creativity to project management, providing solutions to complex challenges that enable projects to come to life.

When away from the studio, Chris enjoys spending time with family and being in nature hiking, camping, climbing, skiing and diving. His passions for travel and photography go hand-in-hand, while he stays mentally and physically balanced by practicing yoga.
