Prairie Spruce Commons

Architectural Rendering Prairie Spruce Commons Cohousing

Architectural Rendering Prairie Spruce Commons Cohousing

Our current project is Prairie Spruce Commons Cohousing in Regina, Saskatchewan, the first cohousing community in Regina. The rendering above is the final design.

The Community

Part of cohousing philosophy and design is to be more ecologically sustainable. By designing smaller private units and sharing common space and amenities we can reduce, among other things, our consumption of construction materials and energy for heating and cooling. Because cohousing is resident designed, the final product typically reflects the values of the community members. It also reflects the site on which it is located.

During several workshops with the architects and consultants we defined our values and desires for our home. Our desire to maximize natural light and have access to green space is reflected in the initial schematic design. This current design includes 27 private units, with full kitchens, varying in size from small bachelor suites to 2.5 bedroom suites.  All units are flat apartment style. The shared common space for community activities currently includes – a large common kitchen and dining room, workshop, children’s playroom, media/TV room, lounge, exercise room, office, sewing/craft room, common laundry, two guest rooms, garden space and outdoor terraces.


Prairie Spruce Commons is a cohousing community committed to building an apartment-style condominium intentionally designed to use resources wisely and to encourage cooperation as well as friendly interaction among residents and neighbors, individuals and families. This inclusive, safe and authentic community is one that respects, shares & cares.

Oak Creek Commons

Entrance to Oak Creek Commons

Oak Creek Commons in Paso Robles on the Central Coast of California is a 36-home cohousing neighborhood.

We found our beautiful land in October 1999. Construction started in 2003 with most of us moving in during 2004. Our final home was completed in the summer of 2005.

We are a community that fosters enriching relationships with one another, nature and the larger community.

Our Values

The Pool at Oak Creek Commons
It is our intention to:

  • Celebrate, accept and welcome diversity,
  • Communicate with integrity, respect and trust.
  • Support, encourage and be compassionate with each other.
  • Live in loving connection while respecting personal space.
  • Create opportunities for fun, laughter, play, celebrations and rituals.
  • Contribute time and talents within our community and beyond.
  • Respect the environment by being sensitive to the interconnections between all things.

Trillium Hollow Cohousing

Trillium Hollow Cohousing Communitu

Trillium Hollow Cohousing Communitu

Trillium Hollow Cohousing began as a group of committed people at a time when there were few cohousing models available. The 12 founders of the community  borrowed against their assets and mortgaged their homes to make this dream happen. All but one was over age 60 when they took out the mortgage to buy this property.

In July of 1994, a notice was posted at the Unitarian Fellowship for folks interested in living in cohousing. That was the start.

Two years later, April 1, 1996, we closed on our new property.

From one of our founders, Joan: That evening we all went to T.H., bringing candles, wine, etc., and chairs.. We sat in a circle in the great room and grinned at each other.  I can’t quite describe it, but my eyes fill as I write it.

We held meetings and symposia to find new members. We hired a cohousing consultant and talked with architects, engineers and contractors. We went through three completely different design plans, lost our first contractor, attempted to integrate the dreams and visions of a dozen people and learned more than we ever expected about site requirements  and watershed protection.

We moved in during the summer of 1998.

Trillium Hollow Cohousing Community

Trillium Hollow Cohousing Community

From Joan: We felt like we were back in college, or summer camp, whatever, but it was one helluva honeymoon.

Today Trillium Hollow is a thriving, multigenerational community with residents ages 3 to 90+ (and every decade in-between). We work together, celebrate together, resolve conflicts with each other and sometimes we mourn together.

From Joan again: Trillium Hollow will always be made up of all of us who ever lived here.

We honor our founders each April. Without their leap of faith, their imagination and their dedication, none of us would be enjoying the remarkable benefits of this beautiful and amazing community.

Winslow Cohousing

Winslow Cohousing ExteriorWinslow Cohousing in Bainbridge, Washington includes 30 homes: 10 townhouse duplexes with 2, 3, and 4-bedroom homes; a fourplex with 1 and 2 bedroom townhouse homes; and the Carriage house with 6 flats of varied sizes. Homes range from 518 to 1500 square feet. Floor plans are similar throughout the village, and many homes have the capacity for some expansion. The duplex and fourplex homes have exclusive use areas (backyards) behind them, with all kitchens facing the walkways, courtyards, and green areas where children can play and neighbors can visit or stroll.

Environmental Concerns

Buildings are sited near each other and parking is located in one corner to preserve wooded areas and open space. Paved lanes connect all the homes, creating the pedestrian neighborhood. All construction is to strict energy-saving standards, and radiant floor heating is standard. Our refuse/recycle center and composting/worm bin projects are part of our care of the environment. Our landscaping uses drought-resistant, hardy, native species, edible by human or wildlife whenever possible. No fertilizers or toxic products are allowed on our land.

Common Spaces and FacilitiesWinslow Cohousing Interior

An integral part of the Cohousing concept is our centrally located 5,000 square foot community Common House. The Common House has dining and meeting space, a large kitchen, a recreation room for children, a fully equipped community office, a guest room, a quiet space, an exercise area, and a laundry for those who do not want laundry facilities in their homes. The orchard is flourishing near the large, sunny community garden. We also have an acre of woods, a children’s playground, a basketball area, a pottery studio, and a workshop.

WindSong Cohousing

Windsong Cohousing

WindSong Cohousing Community incorporates the best of urban and rural lifestyles. Our property is rich with indoor and outdoor beauty.

Our 34 townhomes are in two long rows facing each other across a pedestrian street. The common house is located midway between the north and south ends. Community streets are covered by a greenhouse-style glass roof enabling us to walk, talk, and play outdoors without getting wet, a significant factor in our west coast rainforest climate! Our building design encourages neighbourly interaction.

Our 5,000 sq. ft. common house includes an industrial kitchen, dining room, fireside lounge, playroom with loft and outdoor play structure, an arts & crafts room, workshop, laundry room, community office and board room, multi-purpose (exercise) room, media room, guest room, three washrooms, wheelchair ramps and an underground parking lot.

WindSong has a balance of public and private spaces. The dwellings are privately owned and each unit is self-contained with its own entrance and private kitchen. There is ample soundproofing between units.

ENERGYBrightly painted stairs at Windsong.
Our design incorporates energy-saving elements such as clustered homes and the glass-covered pedestrian street.
Other features include low-flush toilets and environmentally friendly building materials.

WindSong has preserved 4 acres in its natural state. Yorkson Creek runs through our forest and wetland areas providing habitat for birds, beavers and fish. Our site features many native plant species. We have organic vegetable gardens, lawns, fruit trees, and play spaces for children.

Composting bins are located in the north and south gardens. Recycling bins are located near the main garbage collection area to recycle paper, glass, cans, and some plastic. Beverage containers and batteries are collected inside for drop-off at the nearby depot.
