Based in Mosman, on Sydney‘s Lower North Shore, Downie North is a residential architecture practice founded by Catherine Downie and Daniel North. We design new houses, alterations and additions, and heritage adaptations across Sydney and in coastal and regional settings.
Our work begins with an understanding of the people who will inhabit a place and the qualities that make it distinct. The movement of light, the invitation of a garden, the character of an existing building and the changing seasons are as important to us as plan and form. We consider climate, materials and construction together, believing that environmental performance should be felt in the comfort, atmosphere and pleasure of everyday life.
We work directly with our clients from the first conversation through construction, alongside the consultants and builders who help realise each project. We bring imagination to the possibilities, rigour to the detail and clarity to the decisions along the way. Our ambition is to make architecture that feels deeply considered yet effortless to live in, and to make the process of getting there clear and manageable.

Catherine Downie
Catherine has a love of landscape and the intangible qualities of place that informs her architecture. She is driven by an enduring curiosity and a commitment to improving the world around her. Her approach is both rigorous and intuitive, informed by a belief that architecture should be modern yet timeless, culturally responsive and environmentally responsible.
As co-founder of Downie North, she brings extensive experience and considered judgement to the studio, continually questioning and refining ideas to create architecture of lasting value.
Catherine has served on architectural design juries, taught design at the University of Sydney and serves as Secretary to the Committee of the Glenn Murcutt Architecture Foundation.

Daniel North
Inspired by the ethos and optimism of the Modernists, Daniel co-founded Downie North to create memorable, enduring architecture that is hardworking, human-centred and deeply connected to landscape.
With a belief that nature is our greatest teacher, his approach brings together an interest in passive environmental design, the art of building and the atmospheric qualities of architecture. He is fascinated by the changing qualities of natural light and the way architecture can make us more aware of time, weather and the passing seasons.
Daniel serves as Treasurer on the committee of the Glenn Murcutt Architecture Foundation, taught at the University of Sydney and served as a design juror for the AIA.
Daniel loves to draw.
