There are only three private homes ever designed by I.M. Pei. This is the last, largest and most significant - and it has never before been offered for sale. Westover House, Fort Worth, 1969: more than 19,000 square feet of landmark modernist architecture on nearly 4 sloping acres in Westover Hills, with a soaring glass-roofed garden room, art gallery, one primary suite, six additional bedrooms, wellness room, heated pool, putting green and hilltop views. An acquisition of genuine architectural and cultural consequence.
