Delridge Neighborhood Development Association
Project: Croft Place Townhomes

This month’s featured project is Croft Place Townhomes, a 3-Star townhome project in Seattle’s Delridge Neighborhood. Developed by the Delridge Neighborhood Development Association, the 21-unit project is a model of quality, environmentally friendly affordable housing. Winner of the 2008 Built Green Hammer Award in the multi-familiy low-rise category, this project not only incorporated green design and building strategies, but also took the next step to include community residents in designing community-wide artistic elements to establishing a sense of place. Croft Place Townhomes is one of the great examples here in the Pacific Northwest that demonstrates how green building can be realistic for affordable projects.
