In 2001, Holst restored a historic, century-old warehouse to create a
center that encourages the exchange of ecologically and socially
responsible ideas, goods, and services. Ecotrust, officially the Jean Vollum Natural Capital Center, is an open, light-filled space for
progressive businesses and nonprofit organizations, that promotes interaction and at some points, even eliminates barriers between tenants.
Ecotrust was the first historic redevelopment in the U.S. to receive a gold-level LEED certification from the U.S. Green Building Council, and the first LEED Gold
building in the Pacific Northwest, heralding the green building movement in the region.
