About Us

Founder and lead architectural designer, Gavin Brownrigg formed Keystone Design driven by the desire to create enduring and authentic homes for New Zealand families.

With an eye for fine detail, Gavin honed his craft through an extensive career in architectural design. 

Keystone Design is driven by a desire to skilfully design elegant, timeless homes of enduring quality, form and craftsmanship. Our aim is to always fully harness a sites true potential and marry this with functionality and practicality. A sense of sophistication underpins all of our building design projects. 

Keystone Design is about creating exceptional spaces to last a lifetime. We favour simplicity, longevity, and quality materials used in a timeless, enduring and classic way.
