For years, even when its creator, Philip Johnson was still alive, the southwest corner of the plaster ceiling inside the Glass House in New Canaan has been sagging. It’s been getting progressively worse in recent years — to the point where three of the doors into the iconic structure (there’s one on each face of the house) could not be opened. About three years ago, those in charge of the National Trust for Historic Preservation site oversaw a temporary stabilization in the troubled corner, working with Brooklyn, N.Y.-based Evergreene Architectural Arts. “It sagged about three inches in that corner,” Brendan Tobin, senior buildings & grounds manager at the Glass House said Tuesday afternoon, standing near Johnson’s building on the Ponus Ridge site. “They stabilized it by putting some lag bolts and washers in place so it would not further sag, and they gave us basically three proposals to restore or preserve the ceiling.”
