That’s why the interiors of what is now officially the Brant Foundation Art Study Center come as such a shock. Gluckman left the spaces largely unencumbered, giving their dramatic proportions full expression.

The second floor, which used to house massive transformers beneath its 32-foot ceilings, is now one of the most compelling gallery spaces in New York. Its beige brick walls and the cleaned-up steampunk gantries that slide across the room on tracks add the kind of industrial frisson of such museums as Dia:Beacon, the Prada Foundation in Milan and the Tate Modern in London. Gluckman added a gantry-like mechanism of his own; mounted on the fourth-floor ceiling, it can move art up and down through 8-foot-by-10 foot openings cut into the building’s floor plates. The hatches that cover those openings are unobtrusive and strong enough to support crowds.

The third floor, with mere 18-foot ceilings, is relatively ordinary (though huge glass windows in the back wall offer Thomas Struth–like views of the surrounding neighborhood). But that just sets the stage for the remarkable fourth floor, where Gluckman’s interventions are most elaborate. First, the architect covered both floor and ceiling in boards of rift-cut, old-growth clear white oak, giving the large room the coziness of a Finnish sauna. (Elsewhere in the building, floors and ceilings are the original raw concrete.) In the center of the ceiling he and project architects Robert White and Edowa Shimizu installed a 10-foot-by-12-foot skylight, made of about four inches of clear acrylic covered with another four inches of water. Sun shining through the water creates dazzling (and dynamic) light-spatters throughout the room. It’s like a James Turrell Skyspace crossed with a David Hockney pool painting; the effect is so diverting that the fourth floor would be a worthwhile destination even without art on the walls. (That said, the 70 Jean-Michel Basquiat paintings in the Brant’s debut exhibition provide a wonderfully frenetic counterpoint to the calmly self-assured interiors.)

The 16,000-square-foot building required multiple infrastructural upgrades. Gluckman installed an elevator (with a slit window) in the southeast corner of the building, and restored and extended a glassed-in industrial stairway in the southwest corner. Both lead to the roof, where the landscape architect Madison Cox arranged paving and shrubs around the skylight-cum-reflecting pool. From bottom to top, the building is one that gives Gluckman, among the top ranks of museum and gallery designers for 40 years, a welcome chance to show just how accomplished he is.
