Trillium Hollow is a suburban cohousing community nested in 4 acres of lush, forested wildlife setting, with a creek and evergreen firs. We are located minutes from downtown Portland, within walking and biking distance of mass transit, parks, schools (Beaverton school district), shops, and medical facilities. Our community includes 28 self-sufficient apartments (studios, one-, two-, three-, or four-bedroom units) with one stand-alone unit, all 29 owned as condominiums. Our common facilities include a 3,600-sq-ft Common House with three guest rooms and generous dining/meeting spaces; indoor and outdoor play areas for children; a workshop; hot tub; 24/7 internet; community laundry facilities; native-plant landscaping; and organic community garden. Our shared community life at Trillium is active: Members gather frequently for meals, work parties, celebrations, and social activities. Our regular celebrations include Winter Solstice, Talent/No Talent Show, Founders’ Day, Summer Music Bash and Halloween. We are a caring, supportive, consensus-based community, seeking to live lightly on the land, working cooperatively with our surrounding neighbors, valuing participation in our community, and living simply. Our vision is to create and live in a community that fosters harmony with each other, the larger community, and nature.
