With floor-to-ceiling walls of glass throughout this Midcentury Modern created by famed Philadelphia architect Robert McElroy is a rare treasure on the Main Line. Sitting on approximately 1.6 manicured private acres, seamlessly blending nature into your home, giving you your own private retreat yet only minutes away from everything. The home?s open concept design allows you to view the 35 foot 5 tier Waterfall and watch the exotic Japanese Koi right from your great room, separated only by a glass wall of windows. The vaulted ceiling Great Room with gas fireplace and hardwood floors, Kitchen, Dining, Master Suite with Steam Shower, and large home office/library are all on the upper floor giving the greatest access to the home?s amazing views and feeling of living in the treetops, as is typical of a McElroy?s upside-down floor plan. Carved into the hillside are the flagstone steps leading first to a flagstone terrace and continuing up to a large private deck complete with Brazilian IPE Wood floors and built-in seating, modern Cable Railings, and gas grill overlooking the 35 foot waterfall and Koi Pond, making it an entertainer?s paradise. There are over 3000 square feet of new Brazilian IPE Wood decks and Cable Railings surrounding the home which allow complete access to the ultimate indoor-outdoor living with gas fire pit and seating areas. The kitchen includes a Miele Induction Cooktop, Bosch Dishwasher, Stainless Steel Refrigerator, built-in oven, granite countertops and is not only open to the dining room but also has a breakfast room and oversized walk-in pantry. The walk-out lower level has a family room, 3 additional bedrooms, large bathroom, large gym and an additional kitchen making it perfect for an in-law suite with it?s own private entrance. The home is protected by a newly installed Generac whole house generator backup system and includes a whole house stereo surround sound system with Mirage speakers.
