Art Stable is an urban infill project in the rapidly developing South Lake Union neighborhood. Built on the site of a former horse stable, the seven-story mixed-use building carries its working history into the future with highly adaptable live-work units.

A novel geothermal heating and cooling system was a hallmark of this project. The project team pioneered the integration of the geothermal system and an augercast structural pile foundation array.

This technology has been tested in Europe, but is the first of its kind in North America. Additional sustainable features include flexible spaces, electric car-charging stations, daylighting and natural ventilation, in-floor radiant heating and cooling, and the ability to accommodate solar/photovoltaic technology.

Despite a very tight urban site adjacent to heavily trafficked streets, Exxel Pacific recorded no loss-time accidents.
