Description

Tucked on the private shores of Tingler Island in Marathon, FL, this one-of-a-kind dual-waterfront estate is where the Florida Keys lifestyle reaches its fullest expression.

The 8' wide by 107' concrete dock accommodates two boat lifts (3,000 & 17,000 lbs) w/ water, electric, & lighting along the full seawall, everything a serious boater needs. The Main Home stuns w/ soaring 18-ft vaulted ceilings, exposed wood beams, & a wall of six floor-to-ceiling glass panels that open to frame the Atlantic as your daily backdrop. The gourmet kitchen features Sub-Zero & Wolf appliances, a Miele coffee system, a 10-ft island, Brittanica quartz countertops, & a temperature-controlled glass wine wall. A sea-inspired chandelier, custom wall paneling & thoughtful finishes flow throughout. The Primary Suite offers ocean views, a floating soaking tub, glass rain shower, dual sinks, & a clever dual-purpose space doubling as a Primary suite & built-in home office. The private Guest Home above the double garage offers 2 beds, 2 baths, a kitchenette, private balcony, & its own washer/dryer-ideal for guests or family. Outside, resort-style grounds include a gazebo w/ marble dining table, outdoor kitchen w/ Lynx premium grill & fridge, beach sand, fruit garden, Tuuci marine-grade parasols, tiki torches, Coastal Source audio, 1,000 gallon gas tank & full home generator.
