Glenstone Expansion

Potomac, MD United States


Project Description

From the Architect:

Glenstone Overview

Located on 200 acres in Potomac, Maryland, Glenstone strives to provide visitors with a seamless integration of art, architecture and landscape. Its first exhibition building, designed by the late Charles Gwathmey, opened to the public in 2006 and hosts exhibitions of artworks drawn from Glenstone’s collection of post-World War II art. The landscape is home to monumental sculptures sited amid rolling pastures and unspoiled woodlands. Admission is always free, and visits are scheduled by appointment to enable an unhurried, intimate engagement between viewers and their surroundings.

Project Description

Glenstone is now embarking upon an expansion to strengthen its commitment to the public. The centerpiece of this project will be a new exhibition building designed by Thomas Phifer and Partners. Its principal feature will be a series of discrete pavilions—in effect gallery rooms—surrounding a central water courtyard, with many of the pavilions devoted to single-artist installations. The building will significantly expand Glenstone’s gallery space and provide increased support facilities. Landscape architects Peter Walker and Partners will oversee a revised masterplan of Glenstone’s landscape. The expansion project will incorporate a new public entrance and visitor amenities to support a more comfortable and rewarding visit.
