Glenstone opened in 2006, culminating a years-long process of collaboration between Glenstone Co-founder Mitchell Rales and architect Charles Gwathmey. In these never-before-shared drawings from the early days of the Gallery design, you can get a sense of how architect Charles Gwathmey thought through the volumes and shapes of the building we know today.

Gwathmey was tasked with designing a space to house a collection that included works of post-World War II art, and at the time was heavily concentrated in works by abstract expressionists and other mid-century movements. The space, lovingly now dubbed Glenstone's "Starter Museum", is a 9,000 square foot fusion of naturally lit stone-floored space with more traditional "white cube" style space, allowing for a variety of settings for artwork to be displayed.

Gwathmey's imaginiation was allowed to run free, leading so signature elements of the building's final construction, including a central wall set at a diagonal, and an eccentrically shaped conference room.

Today, the Gallery hosts changing exhibitions in generously proportioned spaces and opens up to a terrace overlooking a pond. A limited palette of materials—zinc, granite, stainless steel, and teak—allows the architecture to exist in harmony with the surrounding landscape and the art it houses. Intentionally situated alongside Richard Serra's Sylvester, 2001, the building represents the integration of art, architecture, and nature central to Glenstone's mission.

The eccentrically-shaped conference room continues to serve its purpose to this day.
