On May 16, Sunnyside Village members Norm and Jennie traveled to Seattle for the Cohousing US Summit, a one-day gathering for anyone drawn to deeper connection, whether they're already living in community, are working to create one, or are simply curious about new models of living well together.
The summit explored how cohousing and other community-rooted housing approaches can strengthen belonging, expand housing options, and support people across all stages of life.
It was a day full of learning, honest conversation, and shared inspiration, where forming communities could discuss their challenges and successes, learn from each other, and exchange advice on how to move their projects forward.
One of the highlights for us was Jennie's participation as a speaker on a panel of forming cohousing communities, where she shared the journey that has taken Sunnyside Village from just an idea to construction beginning this year.
We also loved connecting with fellow cohousers, professionals in the field, and people who were simply curious about what community-centered living can look like. It was a powerful reminder that what we're building at Sunnyside is part of a much bigger movement, and we came home feeling energized and grateful to be part of it.
What Exactly is a Common House?
If cohousing has a heart, it's the Common House. But what exactly is it?
Sunnyside’s future Common House
Think of it as a shared extension of your own home, a welcoming space that belongs to everyone in the community. At Sunnyside Village, our Common House will be around 3,000 square feet and designed to be the place where community naturally happens.
At its core, it's built around a communal kitchen and dining room where neighbors come together for regular shared meals, one of the true cornerstones of cohousing life. But it's so much more than a place to eat. It's where you might join a movie night, play board games with neighbors of all ages, share a glass of wine at the end of a long day, or sit down for a quiet cup of coffee on a slow morning.
The Sunnyside Common House will also include a children's room where kids can play safely while parents are nearby, a dual-purpose room that serves as a quiet workspace during the day and a craft room in the evening, two guest rooms for when friends or family come to visit, laundry facilities, a comfortable living room for smaller gatherings, and an outdoor patio for picnics and warm-weather hangouts.
The Common House also serves a practical purpose. It's home to shared resources like tools and equipment, which means less clutter in your private home and less need to buy things you'll only use once or twice. It's also where community meetings take place and where celebrations, holiday gatherings, and events bring everyone together.
What makes a Common House different from, say, a clubhouse in a typical neighborhood is how it's used. It's not a space you reserve or visit occasionally. It's woven into everyday life. Some days you'll pop in for five minutes, other days you'll spend an entire evening there. The beauty is that it's always there when you want it, and completely optional when you don't.
It's one of those things that sounds simple on paper but completely transforms what it feels like to live in a neighborhood.
