Simply remarkable. This spectacular, custom Irvin Construction home is offered turnkey and is situated on an incredibly rare 4.75-acres, enjoying scenic views of beautiful Lake Markham, tucked away at the end of a cul-de-sac street within one of Seminole County's premier luxury gated communities Lake Markham Preserve. This expansive property exudes a fantastic lifestyle thanks to its incredible attention to detail, both interior and exterior. Boasting nearly 6,000 square feet of living space with its five large bedrooms, five full en-suite baths, plus two half-baths, each space is generously sized and well-appointed. After being greeted by the guard at the entry gate and approaching the cul-de-sac of Islewood Court, the impressive facade comes into view. The enormous circular brick paver driveway is appropriately sized for such a large estate. Upon entering, the attention to detail is astounding. Impeccable travertine flooring, an exemplary mix of design materials and an immaculate expression of craftsmanship is found throughout. The living room enjoys large windows overlooking the lanai and pool with splendid views of Lake Markham, while a purpose-built entertainment bar is ideally situated for entertaining family and friends. A private office and dining room are steps away, while the master suite resides down a private hall. The heart of the home is the chef's kitchen featuring dual Sub-Zero built-in refrigerators, Wolf double-wall oven and gas cooktop complete with a large exhaust hood. The family room enjoys a gas fireplace, powder bath access and large pocket sliders which open into the lanai and allow stunning lake view from both the main living spaces. The lanai and pool are wrapped in natural travertine decking and the summer kitchen is complete with a Wolf grill, lots of countertop space, plus a sink and fireplace. Taking a dip in the pool is an understatement, thanks to its Endless Pools system, which creates a current to swim against for those who like a real swim workout. Relax in the spa after a game of tennis or basketball on the lighted Har-Tru tennis court/half basketball court. The lifestyle this home provides is simply outstanding. Tucked away within a few steps of the summer kitchen are the gym/guest suite and the second half bath. Stroll upstairs for more fun in the game room, complete with pool table, balcony and microwave bar perfect for popping popcorn on the way to the home theater. Bedrooms four and five are also found on the second floor, while bedrooms two and three reside on the first floor, all with private en-suite baths. The generously sized laundry and convenient mudroom area are down the hall, en route to the oversized four-plus car garage. Mature landscaping, brick paver sidewalks and delicate use of exterior lighting bring an engaging evening impression. In addition to the amazing lifestyle this home brings, a wealth of outdoor activities is available nearby, including golf and country clubs, walking and hiking trails and easy access to attractions and the beaches. Seminole County enjoys top-rated schools, and boutique dining and shopping are just moments away, as are Interstate 4 and the 429/417 beltways.
