Welcome to 171 3rd St Key Colony Beach where every day you will feel like you are in Paradise! This isn't your average half-duplex--and that's exactly the point. Elegant, Sophisticated, and Spacious with Soaring double-height windows flooding the space with natural light, beautifully highlighting the home's thoughtful updates and rare architectural features. From the protected staircase and grand double-door entry to the electric shutters and transom windows throughout, every detail reflects quality and intention. With over 1,400 square feet, up to 12 foot ceilings, and an open, well-proportioned layout, this two-bedroom, two-bath home offers both volume and everyday livability. A true standout, the kitchen offers generous proportions, custom design, and finishes that balance style with function. Both bathrooms are finished in marble and were updated in 2023 with new vanities and mirrors. Additional upgrades in 2023 include electronic blinds in the family room and all-new landscaping in both the front and backyards. Wide plank flooring flows throughout, and the home is equipped with impact-rated windows and doors. Enjoy multiple outdoor living areas including a screened balcony off the main living level, a private balcony off the primary suite with a peek-a-boo ocean view, and a backyard patio framed by brand-new pavers that extend from front to back. The oversized guest bedroom currently features a king-size bed with room to spare. A dedicated laundry room and small office nook add everyday convenience. Two lower-level spaces--one finished and air-conditioned at 422sf, the other 171sf--offer versatile bonus areas well-suited for storage, gear, or overflow space when needed. This home features 30 feet of dockage with step-down composite decking, offering quick, easy access to open water five minutes away at idle speed. Short walk to white sand beach. One of the most distinctive half-duplexes on the island--worth seeing in person to appreciate just how stunning it is!
