Description
Bold design and thoughtful details set 3801 Flagler apart. This is not a copy-and-paste Key West home—it's the personal residence of an architect and a real estate broker, created to balance striking style with everyday comfort.
Set on a generous 9,500 sq ft corner lot, the property features two distinct structures. The main residence showcases soaring 18-foot vaulted ceilings, a chef's kitchen with gas cooking and stainless appliances, a serene bedroom suite, and a spa-inspired bath. A sculptural concrete-and-metal stair leads to a versatile loft, perfect for reading, work, or creative retreat.
The detached, oversized two-car garage, built in 2021 is rare for Key West—not just for storage but also climate-controlled, making it ideal as a gym, workshop, or (music) studio. Above, a 696 sq ft guest suite offers treetop privacy with flexible living space, bedroom, full bath, coffee bar, and a walk-in closet.
Elevated above FEMA flood zone AE-8 and recently improved, the home is built for longevity and ease of ownership, with a whole-house generator for peace of mind during power outages. Outdoor spaces are just as intentional: a two-tier saltwater pool and deck framed by mature landscaping, coastal breezes, and custom corrugated metal and wood fencing that doubles as a design statement and privacy screen.
For collectors, the restored 1974 Toyota Land Cruiser currently housed in the garage is available under separate negotiation.
With its combination of architecture, flexibility, and outdoor living, 3801 Flagler delivers more than just a residence—it's a modern island compound with expansion potential, now priced to sell.
