Set on approximately 1.25 acres along a private street, this magnificent waterfront home offers a rare combination of architectural charm, modern convenience, and everyday livability.
A thoughtful floor plan spans three levels, anchored by open living and dining spaces framed by panoramic lake views. Two primary suites with spa-inspired baths and walk-in closets provide privacy and comfort, while additional bedrooms, a dedicated sunroom/office, and a third-floor cinema room accommodate every lifestyle need.
High ceilings, crown molding, hardwood floors, and walls of windows create an atmosphere of light and sophistication while an elevator ensures effortless movement between levels.
Outdoor living takes center stage - an expansive front porch invites you into the home while a screened porch facing Lake Pontchartrain provides easy access to the pool, pier and grounds. Two balconies one floor above offer similar views from either side of the house and are only topped by the comprehensive views from the rooftop widow's walk. You'll be spoiled for choice when it comes time to enjoy stunning western sunsets over Lake Pontchartrain.
Waterfront amenities include a private pier with fishing light, two boat ramps, covered boat/car parking, and an above-ground pool surrounded by lush landscaping.
On the ground level, the covered carport area offers not only parking for multiple vehicles and boats but also a half bathroom and two storage rooms — perfect for stowing fishing gear, boating equipment, or poolside essentials.
Whether as a full-time residence or weekend retreat, 21 N Treasure Isle is designed for those who seek luxury, comfort, and the unmatched lifestyle of living on the water.
