The project
South Flagler House is Related Ross's two-tower, roughly 103- to 108-residence project at 1355 S Flagler Drive in West Palm Beach, with architecture by Robert A.M. Stern Architects (RAMSA). The project is under construction and now selling, with pricing from about $6 million to $7.48 million and delivery guided to 2026-2027.
Two- to five-bedroom residences across the 28-story towers occupy a premier south Flagler position. RAMSA's classical-modern architecture differentiates it from the corridor's glass towers.
