We began working together in 1968 and have built an international reputation as one of the most innovative and integrated architecture and design practices in New Zealand.
Our team is a close-knit group of specialists in architecture, interior design, urban planning and landscape architecture.
We design by researching and challenging — by asking the right questions — and are guided by an unswerving sensitivity to the culture and climate of a place.
We make architecture that responds with spirit and ingenuity to the pressing challenges of our time: the need for sustainable design, quality
housing, public buildings and spaces that reflect the community, and genuine collaboration.
