Guna Collaborative was established in 2023 in Portland, Oregon.

It was formed by John Holmes, former founding partner and design director at Holst Architecture (1992-2017).

Guna, which means attribute or quality, strives to synthesize those properties which lie at the root of Architecture: light, line, and materiality. The circumstances of each project–its constraints, opportunities, location–serve as the departure point for wholistic and meaningful Architecture.

Current projects include: a major campus redesign for the French International School of Oregon, a 600 unit Multifamily community in Tigard, Oregon, and a modern cottage cluster in Gresham, Oregon.
