What we do

We are a suburban cohousing community in Portland, OR, nestled in 4 acres of lush, forested wildlife setting, with a creek and evergreen firs. Trillium Hollow is located minutes from downtown Portland, within walking and biking distance of mass transit, parks, hiking trails, 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 including 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, Progressive Dinner, Summer Bash and Halloween Party, to name a few. 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.

Our Mission

We, the members of Trillium Hollow Cohousing Neighborhood, commit ourselves to the creation and maintenance of a supportive, enriching, and purposeful community that fosters the spiritual connection among ourselves, others, and the earth through simplicity, cooperation and service.

Worktrade Opportunities on Big Island Hawaii

We are continuing our work-trade program at Bridge Hawaii for the right people on this beautiful 86-acre land located along the Hāmākua Coast. Ideally, we want to host those individuals who can help with the garden and who can support with build projects for up to a 3 month stay. This work-trade would include lodging, food staples, community kitchen, running hot water showers, off-grid electricity, and laundry. There is access to high speed wi-fi. We often have a car that can be reserved. We also have full bar signal strength with Verizon cellphone service. We have about 2 acres of permaculture garden that needs to be cared for including; weeding, planting, picking up mulch, some tree trimming, ect. We are currently in a building stage on the land. We have a few current grant projects we are working on and some build projects that are underway. We are an intentional community with about 8 permanent residents. There are rescue dairy cows, mini cows, mini donkeys, horses, a donkey, cats, dogs, and active bee hives. We are a drug and alcohol “free” space. A glass of wine or beer with dinner is fine, but absolutely no day drinking or parties. We have a meditation temple and many waterfall pools that are wonderful for swimming. Close to some of the nicest beaches on island. We have snorkeling gear and a kayak. Since this is an animal sanctuary, we limit the consumption of meat on the land. Fish, eggs, honey, and dairy are fine. Let me know if you’re interested by sending an email or text for our application. Maomi (801) 623-0738 ma***@*****************ii.com
