Built Green 4-Star certified 4-Verified, not advertised

Built Green is the residential green-building standard of the Master Builders Association of King and Snohomish Counties. A 4-Star rating is awarded after third-party verification of energy efficiency, water conservation, indoor air quality, materials sourcing, and site impact. Stream Dexios was certified at completion in 2020 and has held it since.

1,800+ trees planted in 4 years.

We collaborate with local leaders in land conservation across Western Washington, and our appliances and fixtures use less water and less energy.

Responsible to neighbors.

Socially responsible is the best way to be responsible. We care about our neighbors, community, and friends — and a sustainable community is one way to do just that.

Built to complement.

The economy suffers if you don’t build to complement your surroundings. We make ecologically sound decisions because they’re the right ones — for you, and for the next forty years of this building.

Living in South Lake Union has many perks. You’re conveniently located to many Seattle neighborhoods, and easy access to I-5 makes 1600 Dexter Ave N the perfect jump-off point for any adventure — from a morning paddle on Lake Union to a quick run downtown.
