A big win for the CornerStone team at the Seattle 2030 District Vision Awards! The project was honored with the Water Vision Award for its Living Building Challenge approach to rethinking how buildings use water.

Designed to meet strict Living Building Challenge requirements, the project captures rainwater onsite, stores it in a 268,745-gallon underground cistern, and reuses it for all non-potable needs like toilet flushing. This system saves about 589,000 gallons of potable water each year and reduces overall water use by 54%, exceeding the 2030 District target.

The project also shows how urban offices can strengthen communities, supporting people who live and work in the same neighborhoods while delivering benefits beyond the building itself. Seattle’s Living Building Pilot Program was key in making CornerStone possible, helping bring a highly sustainable project to market. Initiatives like this are essential to support and advance developments like these.
