Robert A.M. Stern Architecture and Pembrooke and Ives Interiors
South Flagler House is developed by Related Ross and comprises two 28-story towers containing 105 residences. RAMSA's design vocabulary here draws on classical proportions and masonry massing familiar from their work at 15 Central Park West and 220 Central Park South in Manhattan. Pembrooke and Ives, the firm responsible for interior design direction, is known for residential interiors that emphasize material warmth and restrained detail. The pairing of these two firms represents a deliberate pitch toward New York buyers already familiar with both practices.
Interior Layout Across Two Floors
A private elevator vestibule opens into a grand foyer that anchors the circulation between both levels. The lower floor contains the primary living, dining, and entertaining spaces, all oriented toward the water with floor-to-ceiling glazing capturing Intracoastal and ocean views. The kitchen, family room, and media room are arranged for daily use, with separate office space on each level.
Seven bedrooms and eight full bathrooms are distributed across the duplex, along with two powder rooms. A private interior elevator connects the two floors in addition to a formal interior staircase. The 28th floor positions the upper bedrooms at the highest residential elevation on the South Flagler Drive corridor, with unobstructed sightlines in every direction.
Covered Terraces and Panoramic Exposure
The 1,941 square feet of covered outdoor space wraps portions of both floors, providing sheltered terrace access from multiple rooms. The southern and eastern exposures deliver direct views across the Intracoastal to Palm Beach Island and the ocean beyond. West-facing terraces overlook the West Palm Beach skyline and the developing urban core along Dixie Highway and Clematis Street.
Building Amenities and Services
South Flagler House provides an attended lobby, key card entry, 24-hour security patrol, fire sprinkler and alarm systems throughout, and a full-service concierge operation. The building's amenity program is among the most expansive per residence in Palm Beach County. Two garage spaces are included with this penthouse.
Location and Access
The 1355 South Flagler Drive address sits directly on the Intracoastal, approximately one mile south of the Flagler Memorial Bridge connecting to Palm Beach Island. Palm Beach International Airport is a seven-minute drive west via Okeechobee Boulevard. The site is within the Jefferson Park area of West Palm Beach, positioned between the Southern Boulevard and Flagler Memorial bridge crossings, giving residents two direct routes onto the island. This stretch of South Flagler Drive has become the most actively developed luxury corridor in downtown West Palm Beach, with multiple new towers either completed or under construction within a half-mile radius.
