The residence

Vertical living, curated from the water to the roof.

519 Rountree was designed as a private coastal retreat: a rare architectural statement positioned on a unique triangular lot with dual water exposure, offering both Gulf and canal views. The home is organised vertically, with a distinct experience on every level and a gallery-inspired aesthetic carried through professional interior curation.

From the street, the triangular balcony face makes the house read far larger than its footprint. Walls of glass pull the light in on every floor. A chef's kitchen anchors the main living level and opens to a BBQ terrace with outdoor kitchen. The spa-style primary bath has a steam shower; there is a private office, two laundry rooms, integrated whole-home audio, and a smart-home system run from its own server closet. A full-home LP gas generator keeps everything running.

Outside, a resort-style pool and jacuzzi sit beside a gazebo with canal access behind a new 34-foot seawall, with a dock and boat lift on the canal. Above it all, a rooftop terrace delivers 360° views: the Gulf of Mexico and its sunsets to the west, the bay side to the east.
