No canal width is published for this dock — we found no facing bank within canal range to measure against.

That is the absence of a measurement, not a finding of open-water frontage. Check the waterway, depth and slip dimensions with the listing agent.

Description

Now priced UNDER recent appraised value of $4,500,000! Embrace the RARE opportunity to own 1.75 acres of open water paradise in the prestigious, gated community of Stirrup Key. Over 600' feet of direct, open Gulf frontage, you'll enjoy spectacular sunrises and sunsets from nearly every vantage point, including a charming sunset gazebo overlooking the iconic Seven Mile Bridge in the distance. The custom Mediterranean-style residence captures the essence of resort living with expansive pavered patios, sparkling elevated pool, and spacious lounging areas absolutely perfect for entertaining against a stunning Gulf backdrop. Five protected basin docks provide sheltered boating access in the marina, while terraced tropical gardens cascade toward the water, lined with mature palms and lush landscaping for a serene coastal ambiance. Inside, soaring cathedral ceilings, wood plantation shutters, and an airy great room with real coral fireplace showcase timeless Keys craftsmanship. The split-bedroom layout ensures privacy, with a luxurious master suite featuring dual closets and skylit bath, plus separate guest quarters. Additional highlights include an elevator, 12,000-gallon cistern, huge garage for cars and golf carts, and a large lower-level storage area with workbenches, pool table, and extra laundry facilities. This gated community, with unique architecture, fewer lots, limited rentals and higher quality restrictions help to sustain a premium and private feel.
