ABOUT25 years of complex architecture.
Now focused on yours.
Peter Spruance is a registered architect based on Bainbridge Island, Washington, with over 25 years of experience designing custom homes, additions, and complex builds across the Pacific Northwest and Rocky Mountain West.
PETER SPRUANCE, AIAPeter spent his early career at Seattle-based firms Suyama Peterson Deguchi and Miller Hull, where over ten years he worked across a broad range of project types, from the Gould Hall Gallery at the University of Washington, a 2,200 SF architectural gallery addition that earned the AIA Seattle 2015 Award of Merit, to the Cascadia Community College Center for Global Learning and the Arts in Bothell, a 50,000 SF LEED Platinum building.
He ultimately served as project executive on the San Ysidro Land Port of Entry, a $480 million, 50-acre campus at the busiest land crossing in the western hemisphere. The project earned LEED Platinum certification and a GSA Design Excellence Award. That experience shaped how he thinks: complex sites have more potential, not less. Constraints are where good design starts.
“Peter is not driven by trends — he is driven by finding the optimal solution for your project and everyone involved.“
Spotswood Architecture + Design was founded in 2021, after a chapter leading building platform development at Katerra. Peter brought that systems thinking back to residential work, a practice now focused on custom homes, additions, and remodels for clients who want a home that genuinely fits their site, their life, and their budget.
He works on Bainbridge Island and across the Kitsap Peninsula, throughout greater Seattle, and along the Olympic Peninsula corridor from Port Townsend to Sequim and beyond. For mountain and remote projects he takes on sites throughout the Cascades into the Rocky Mountains, including Teton Valley, Idaho, Utah and Colorado. Complex terrain and technically challenging sites are a specialty, not an exception.
Peter is a registered architect in Washington State and a member of the American Institute of Architects. He has been a guest lecturer at the University of Washington and serves on the UW Professional Advisory Council. When he is not working, he skis, spends time with his wife and two daughters, and builds furniture in his workshop on Bainbridge Island.
