It's time to unveil the pinnacle of lakefront living in IL, as this newer construction estate is better than brand new construction as it encompasses features that could never be built today with the new lakefront building ordinances. Try to top this...your personal wellness club that is only 20 steps out to your own private, 141-foot wide, sandy beach with indoor pool, sauna, and state-of-the-art gym, to outdoor entertainment space with built-in bluff terrace, 20x40 pool & spa with matching cabana, enclave fire pit, outdoor kitchen and grass tennis court. And the inside...first start from the very top by taking the elevator to the 3rd floor: where guests can have privacy in the in-law suite with a bar, studio, and private patio with panoramic lake views. Hit the 2nd floor with 5 more beds, laundry, and posh master suite with marble bath and jaw dropping lake views, 2 walk-in wardrobe rooms and massive bedroom with fireplace and private patio. Now for the main floor... a dramatic entry with cascading bridal staircase that was made famous with the hit show "Empire" will seem familiar as you step into the reception hallway with 15-foot soaring ceilings. Sun-drenched formal rooms with a stoic mahogany paneled office where deals get done as you step right out the French doors to the pool area. The great room is the perfect viewpoint to capture all the magnificent outdoor fun zones through the floor to ceiling windows with the blues of the lake in the distance. A kitchen that no real chef cannot fall in love with...double islands, endless counter space, all high-end appliances, even a built-in rice maker. The Solarium breakfast room allows for non-depressing meals even on a rainy day and a fabulous sun room with terraced patio for private conversations. Now down to the lower level as there is not one thing missing... theater room, wine room, bar, massive rec room for teenage parties and that secret tunnel to your own wellness wing. Of course, an attached 4-car garage, private gated entrance & motor court drive. No words can really bring this estate to life as only a private tour can bring this living experience to reality. No need to build... as this would cost over $55 million minimum to replicate. Your smartest lakefront investment is now available and even with lake front homes it's still about location, location, location. 319 Sheridan Rd. is the PRIME part of Sheridan Road where two other $30 million plus homes have just closed in the last year as these homes are not high in the bluffs but are in-town estates. Walk to Greeley & New Trier in 10 minutes, ride your bike to town in 5 minutes, jump on the train for a 29 minute ride to the city, and best yet...spend only 3 minutes pulling out your boat from the commercial level boathouse right into the gorgeous waters of Lake Michigan from your own private sandy beach! Private lakefront fun zone...enter at your own risk!
