35 Stone, a new mass timber office and retail building designed by Weber Thompson recently completed construction. Sourced from the forests of the Pacific Northwest, the glulam and dowel laminated timber (DLT) structure sets a precedent for environmentally sustainable development while pursuing Seattle’s Living Building Pilot Program (LBPP) and Petal Certification from the International Living Future Institute’s (ILFI) Living Building Challenge. Developed by evolution Projects, 35 Stone is a top-of-class workplace that attracted a full-building tenant, Brooks Running, with a forward-looking biophilic design that promotes health and wellness and an active lifestyle.
“35 Stone’s unique form pays homage to the neighborhoods’ industrial past while looking to the future of healthy, community-oriented workplaces,” states Weber Thompson Principal Cody Lodi, Design Lead for 35 Stone. “The balanced daylighting design and biophilic cues from the exposed mass timber along with spaces for social connection at all levels ensure that tenants will thrive in this groundbreaking project.”
Supporting Seattle’s climate mitigation strategies, 35 Stone’s participation in the LBPP provided height and floor area incentives in exchange for meeting high-performance green building requirements, including ILFI Petal Certification. 35 Stone is tackling the rigorous deep green certification requirements, including a minimum of a 25% reduction in energy use, no potable water used for non-potable uses like toilet flushing and irrigation, and construction with healthy building materials. Utilizing glue-free DLT, 35 Stone embraces healthy building materials with one of the most sustainable mass timber options on the market. The mass timber framework is complemented with operable windows, heroic balconies, and a large roof terrace, providing biophilic benefits to tenants.
“With two Living Building Projects completed, we are seeing the power that incentive programs have to help market rate projects achieve these high-performance building goals,” states Weber Thompson Managing Partner Kristen Scott, the Principal in Charge of 35 Stone. “The alignment between the LBPP and the focus on healthy, productive workplaces has never been more clear.”
As a regenerative, deep green building 35 Stone promotes the environmental stewardship of our urban ecosystem. Its hybrid mass timber-concrete structural system saves 1,886 metric tons of CO2e, a 35% reduction in its carbon footprint compared to a typical concrete and steel structure. Its massive 268,745-gallon cistern can store enough rainwater for all non-potable water demand, allowing the building to be self-sufficient for non-drinking water needs indefinitely, reducing the total demand on domestic water by 54%. 35 Stone also supports our local ecology and agriculture by caring for bees and other pollinators with plantings and a rooftop apiary alongside bioretention planters that clean stormwater runoff.
35 Stone is located at 3524 Stone Way N, anchoring evolution Project’s decade-long vision for Campus Seattle, a full-block development. This full-block development stands at the base of the rapidly evolving Stone Way corridor and includes The Fremont Collective and Bouldering Project.
“We are beyond excited to celebrate the opening of 35 stone. The project not only marks the confluence of sustainability and community-focused design but also serves as a symbol of resilience from the development team to the community at large during the challenging climate of COVID-19,” states evolution Project Director of Design & Development Jieun Shon. “We look forward to the unveiling and watching it flourish into a place of servitude for the Fremont community that has withstood a lot in recent years.”
Sellen Construction is the general contractor for 35 Stone’s core and shell as well as Brooks Running’s tenant improvement, which is designed by NBBJ. Occupancy is expected this fall.
