What is cohousing?

Each cohousing community is unique. It’s a custom neighborhood after all! Some start with missions that are focused for their particular residents and all evolve to reflect the specific group’s growth in social connectivity and resolution process. Senior cohousing naturally has a different vibe than intergenerational cohousing. Urban and rural cohousing neighborhoods deal with different constraints and opportunities in design and membership outreach. Core resident groups may be started in a Unitarian Church, an LGBTQ community center, or an urban meetup of homeschoolers.  Each of these offer a distinct perspective on how their residents agree to live in each community. 

There are, however, common features of cohousing, which have worked well for decades and that people keep gravitating towards this style of living:

• Cohousing is designed, owned, and managed by the residents.
• The greater good of the community is valued more than individual needs.
• Sustainability is inherent in cohousing design and development, as well as most residents' lifestyle choices.
• The common house and other amenities are integral to the daily lives of the residents and become an extension of the private homes. The private units are full residences with kitchen and bath(s).
• Cars are kept at the perimeter of the site and pedestrian paths promote health and spontaneous interaction.
• Participation is key to a thriving cohousing community, from the design process through everyday life in the neighborhood: regular common meals, essential committee work, and lots of playful times too.
• The decision-making process is non-hierarchical. Some communities practice consensus resolution; some use sociocracy. All try to hone their processes to fit their members, so that they are efficient, effective, and fair.
• Oh and it's NOT a commune. There is no shared economy.

Where can you find cohousing neighborhoods?

United States has 165 established cohousing communities with another 140 in formation.  Only the Netherlands and Denmark has more with 8% of Danish households live in cohousing.  Architects Katie McCamant and Chuck Durrett lived in and studied cohousing in Denmark before they wrote the book on it in 1987 and started designing and developing them back home in the US, starting on the west coast.  There was an east coast contingency too with an early hub in Massachusetts, designed by Kraus Fitch Architects.  Here are some wonderful examples to peruse:

How do cohousing projects get developed? What’s the process like?

While the various steps within the cohousing development may vary and do not always occur in the same sequence, the main phases and milestones are consistent:

  • Establishing the resident group and the professional team

  • Site research and acquisition

  • Design workshops, documentation, and submittals to the municipality

  • Construction and sales

In each phase, the resident group’s participation is essential for outreach, marketing, social community strengthening, design participation, and investment. Cohousing Opportunities Group and Lynn Gaffney Architect work in collaboration with the residents—educating, gather, facilitation, researching, designing, presenting, and bringing in consultants and developers. There is a lot to do; let us provide guidance and expertise.
