579 COMMONWEALTH LANE, Siesta Key, FL, 34242 | $5,500,000

Pre-Construction. To be built. Welcome to a world where every day feels like an escape to Paradise! This meticulously crafted 4, 500 sq. ft. residence on Siesta Key blends contemporary architecture with earth tones, rich natural materials, and an undeniable sense of calm—evoking the ambiance of a private luxury retreat.

Designed for both serenity and spectacle, the home features 5 spacious ensuite bedrooms and 5. 5 baths, each curated with refined finishes and organic textures. The design leans into warmth—stones, layered woods, soft organic tones, and a sense of ease that feels more high-end boutique resort than new construction.

An airy, open-concept living space flows seamlessly to the outdoors, where the amenities rival a five-star resort. Enjoy a fully outfitted outdoor kitchen, a stunning sunken firepit, and generous covered lounging and dining spaces overlooking the water. Whether you’re hosting sunset celebrations or savoring quiet mornings off the canal, every moment feels like an experience.

Wellness enthusiasts will appreciate the private home gym, while boating lovers will relish the canal access and dock, offering quick passage to the Intracoastal and beyond. Boat weight capacity is 12, 000 lbs (with no low bridges in the way).

This home has the feel of a luxury resort, but with a warmth and simplicity that makes it easy to imagine living here every day. Construction is underway, and it’s one of those rare opportunities where you can secure the lifestyle before the final touches are even complete.

Live where luxury feels natural. Live where every day feels like vacation. Welcome to your future on Siesta Key. Builder: Design 2 Build, est. completion: December 2026.
