Designed for my clients 51 years ago by Charles F.D. Egbert, this well-preserved 1968 mid-century modern in Glen Echo Heights was featured in Better Homes and Gardens. The three-level house (including basement) with 3 beds and 3.5 bathrooms features a main level living room with 21-foot ceilings and walls of expansive glass. The exterior is clad in redwood. Sold before going on the market.
