The practice of architecture is a highly personal service. Particular attention must be paid to the people involved in the conceptualization and construction of a successful project.

Castanes Architects presents almost thirty years of architectural work on a variety of building types throughout the Pacific Northwest. We are a small, client-oriented office with a fun, unique and constantly evolving collaborative approach to design projects.

From the initial site development, to the most intricate details, our work represents the culmination of clear communications and careful management of the expectations of our clients.

Relying on design and technical proficiency, our goal is to deliver a project that provides a positive sense of achievement for the entire project team of owner, architect and builder.


Jim Castanes

Award winning Architect Jim Castanes, AIA, founded Castanes Architects in 1984 with the goal of creating spaces that enhance the environment and the community as a whole. The influence of his extensive European travels can be found in many of the firm’s projects. His work has been featured in The New York Times, Luxe Magazine, Seattle Homes & Lifestyles, Northwest Home, and many other regional publications.  



Jordan Cowhig

Jordan (or Jo) has been with Castanes for the past 6 years as a project designer and manager. You will often see her swiftly walking around Seattle with a cup of coffee in one hand and dog leash in the other. Inspired by the dynamic of modern day human desires versus the simplicity of nature, she creates spaces that portray a collaboration between the two.

Originally from the midwest, but coming to Seattle to study Architecture and Construction Management at the University of Washington, she is knowledgable in designing for a multitude of climates. Her combined degrees of Architecture and Construction Management give her a deepened understanding of the process as a whole, start-to-finish - as such, she integrates the processes of designing and building, while also advocating for her clients throughout construction.
