18501 Collins Ave 4003-04 Presenting The Sky Estate at Turnberry Ocean Club - one of only three developer-combined residences in this iconic Sunny Isles Beach tower, and the highest-floor combined residence in the building. Set within an all-glass tower engineered for 360-degree water views, this residence captures both the Atlantic Ocean and the Intracoastal - the water never leaves your sight. Spanning an entire half-floor, it offers a scale rarely available on the market. The residence delivers 6, 740 SF of interior living space plus over 1, 510 SF of terrace space, for over 8, 250 SF total. Two expansive 80-foot wide terraces - one oceanfront, one facing the sunset, intracoastal, and skyline- flank the residence, while the combined floor plan creates exceptionally wide-format living spaces framed by floor-to-ceiling glass on both exposures. Interiors feature fully custom build-outs with designer wood paneling, dimensional ceiling lighting, and more. 5 bedrooms plus office/den, 7.5 baths. Never lived in. Never touched. Residents enjoy over 70, 000 SF of amenities across six floors, including the 3-story private signature 'Sky Club, a $100 million investment: oceanfront pools, spa & wellness, fitness center, theater, full-service concierge, multiple restaurants, and more. This is not simply a residence - it is a rare condo with two backyards in the sky, and one of the most significant offerings to reach the Sunny Isles Beach market.
