Letitia Ave Development

Two new houses in the Columbia City neighborhood of Seattle.

Our first project, designed by Patricia Bittner and built by Case D&PM. These homes were a testing ground for resource-and-energy-efficient construction methods. An ICF Foundation system, Cellulose Insulation, and Radiant Floor Heat all provide for winter comfort, while lots of natural ventilation tempers summer extremes. The low-maintenance membrane roof and rain-screen exterior provide a longer-lasting home. Like all of our projects, these homes are highly efficient in their use of space and materials. They look out across their neighborhood toward the Cascade Mountains. For an article about their owners, and more interior photos, click here.
