INDOOR-OUTDOOR CONNECTION The pavilion scheme of Greenwood Garden Home is completely connected to its landscape. The kitchen, dining area, and living space link to the front, side, and backyard gardens with a variety of thoughtfully placed openings. A dry garden on the street and raised beds for veggies and herbs can be accessed by the kitchen door as well as the front entrance. A northwest garden with native perennials fills the backyard.

“From our very first meeting and every meeting thereafter, we worked with our clients to integrate their gardening goals with their architectural goals. The results are stunning! This home, located on a compact urban lot, connects to carefully planned garden spaces on three sides - without sacrificing privacy.” — Tim Hammer, architect

The abundant natural light and views of greenery work to both elevate and expand this home’s modest footprint.

The SEATTLE DAILY JOURNAL OF COMMERCE wrote this great story about the redevelopment of Nəxʷq’íyt (“Noo-kayet”) Point. This project marks the return of the ancestral village of the Port Gamble S’Klallam Tribe to its native people.

(No Paywall – Thank you, DJC!) Written by Nina Milligan.

Part of a decades-long environmental restoration of Port Gamble Bay, this project transforms a site once dominated by a 19th-century sawmill into a place that celebrates renewal—ecological, cultural, and communal.

Demolition Party! FYRE staff, supporters, and community members helped clear the way for the FYRE Village Youth Shelter by kicking off the demolition of the empty building at 9 Ash Street! Construction on the new facility will begin in earnest in early 2027.

The Foundation for Youth Resiliency and Engagement (FYRE) is an innovative grassroots organization serving young people 12-24 across Okanogan County.

Their services include educational advocacy, supporting young parents, increasing accessibility to whole-person health services, and providing referrals and resources to youth experiencing homelessness and sexual exploitation.

CAST is working with FYRE to design a residential shelter providing emergency and transitional housing for homeless youth. This new facility will also include various support functions, such as shared cooking and social spaces, as well as intake/counseling offices.

The Refugee Women’s Alliance is a non-profit organization that provides refugee and immigrant women and their families with culturally and linguistically appropriate services. Founded in 1985 by a group of successfully resettled refugee women, ReWA provides wrap-around services to more than 11,000 clients from over 70 different countries of origin.

We designed this 6,500 SF addition that combines a large community Gathering Hall, an Early Learning Center for 40 children, office space, and extensive site redevelopment. The space reflects ReWA’s core mission: to be a sanctuary for people who have traveled a long and difficult path. The building is LEED certified.

At 997 square feet, this Sedge Cottage in Ballard provides well-daylit living space, essential storage, and two covered outdoor porches.

Within its compact form, there are three bedrooms and two baths, a galley kitchen with a peninsula, and ample storage. It features a bedroom and 3/4 bath on the main level that works well for an aging parent, as a guest room, or work-from-home office. The front porch clearly marks the entry of the accessory dwelling.

The design targets 4-Star Built Green, with details for reduced air infiltration, energy-efficient heating, cooling, and water heating systems, passive solar heat gain in window/shading in summer, low-VOC finishes, no fossil-fuel appliances, and all LED lighting.
