The Building
South Flagler House is Related Companies’ first luxury residential condominium in Florida and Robert A.M. Stern Architects’ first luxury residential high-rise in the state. The two firms, whose collaboration spans more than two decades and 17 buildings, are delivering 108 residences across twin 28-story towers on the Intracoastal Waterway in West Palm Beach.
The Lake Tower and Park Tower rise from a landscaped base of stepped gardens, with eastward views across the Intracoastal toward Palm Beach Island. RAMSA’s design draws from the architectural vocabulary of Palm Beach’s 1930s-era buildings. Flow-through floor plans provide exposure on multiple sides of each residence.
Developer Stephen Ross founded Related Companies in 1972, building it into one of the largest privately held real estate firms in the United States. His portfolio includes Hudson Yards in Manhattan (the largest private real estate development in U.S. history) and the 72-acre CityPlace (now The Square) redevelopment in downtown West Palm Beach. Interior design is by Pembrooke & Ives. Coastal Construction serves as general contractor.
Delivery is anticipated in 2027. Residents will have access to private club amenities and enrollment in The Related Life, a concierge and programming platform operated by Related Companies.

Pricing is set by the developer and moves as inventory sells, so we do not publish a fixed price list here. Tower residences with two to four bedrooms and 2,196 to 4,500 square feet of interior space represent the entry tier. Half-floor penthouses on floors 25 through 28 range from 5,500 to 6,450 square feet. For current availability and pricing, contact our advisory team.
Full-floor penthouses at the top of each tower provide more than 10,000 square feet of living space. These penthouses are delivered as custom builds by Rogers General Contracting (a Related Ross affiliate), allowing buyers to configure layouts to their specifications. A duplex penthouse is also available.
The price range places South Flagler House at the upper end of the West Palm Beach new development market and overlaps with resale inventory on Palm Beach Island. Buyers evaluating this price tier should compare the per-square-foot basis relative to comparable condominiums and waterfront properties in the area.
South Flagler House contains 108 residences across two 28-story towers, the Lake Tower and the Park Tower. Floor plans range from two-bedroom residences of approximately 2,196 square feet to full-floor penthouses exceeding 10,000 square feet. All residences have flow-through layouts with exposure on multiple sides.
Three residence categories are available. Tower residences include two- to four-bedroom layouts with 2,196 to 4,500 square feet of interior space and private elevator access. Half-floor penthouses occupy floors 25 through 28 and provide 5,500 to 6,450 square feet with four to five bedrooms. Full-floor penthouses encompass the entire floor plate and are delivered as custom configurations.
Residences can be combined to create larger layouts. Interior design by Pembrooke & Ives establishes the finish palette, with covered loggias and deep terraces extending the living area outdoors. For a comparison of floor plans and pricing at this and other new developments, or to explore waterfront properties across Palm Beach County, contact our buyer advisory team.
Delivery is expected in 2027. The project broke ground in April 2024, and both towers topped off at 28 stories in November 2025. Interior finishing and amenity buildout remain before the certificate of occupancy. The schedule has met each milestone since the site purchase in August 2023. Completion dates move, so the contract’s outside date and remedies matter more than the marketed year. Buyers should weigh each project’s stage against its deposit schedule and closing timeline. Contact us for guidance on comparable new construction.

South Flagler House provides approximately 50,000 square feet of private club amenities across both towers and the ground-level landscape. Fitness facilities include a gym, Pilates studio, yoga studio, and an outdoor yoga lawn. A lakefront lap pool, pool cabanas, and a full-service spa with hydrotherapy and beauty salon anchor the wellness offering.

Related Ross, the South Florida arm led by Stephen Ross, is the developer. Ross founded Related Companies in 1972 and built it into one of the largest privately held real estate firms in the United States. His portfolio includes Hudson Yards in Manhattan and the 72-acre CityPlace redevelopment in West Palm Beach, now The Square. Robert A.M. Stern Architects designed the building. Related and RAMSA have worked together for more than two decades on 17 buildings, including 15 Central Park West and 220 Central Park South.
South Flagler House is their first residential project in Florida. Pembrooke & Ives designed the interiors and SMI Landscape Architecture the landscape. Contact us for building-by-building comparisons of developer portfolios across Palm Beach County.
Monthly HOA assessments for South Flagler House have not been finalized during the construction phase. Comparable new-construction waterfront condominiums in West Palm Beach and Palm Beach County carry monthly assessments that scale with amenity scope and staffing levels.
Given South Flagler House’s 50,000 square feet of club amenities, 24-hour staffing, valet service, and The Related Life programming, buyers should anticipate assessments toward the higher end of the local market range. The 108-unit count distributes operating costs across a relatively small ownership base compared to larger condominium buildings.
HOA assessments in Florida typically cover building insurance (excluding unit interiors), common area maintenance, staffing, amenity operations, and reserves. Buyers relocating from states with different condominium governance structures should consult with local counsel regarding Florida’s Condominium Act (Chapter 718). For guidance on carrying costs across new developments in the market, contact our advisory team.
South Flagler House is a poured-in-place concrete structure designed by Robert A.M. Stern Architects and built by Coastal Construction, a large South Florida general contractor. The building is designed to the current Florida Building Code, which is among the strictest in the country for wind and flood. Residences are delivered with finishes by Pembrooke & Ives, including imported stone, custom millwork and fully equipped kitchens.
High ceilings, private elevator foyers, separate service entrances and covered loggias are standard. The Lake Tower and Park Tower sit around a landscaped motor court, which gives multiple exposures and cross-ventilation. Full-floor penthouses are custom builds by Rogers General Contracting, a Related Ross affiliate. We provide building-by-building comparisons of construction specifications across West Palm Beach.
South Flagler House sits at the upper end of the West Palm Beach condominium market by asking price, and its ceiling exceeds most current local inventory. Its closest comparison is The Bristol, 69 residences on South Flagler Drive completed in 2019, also designed by Robert A.M. Stern Architects. South Flagler House offers larger floor plans, two towers and about 50,000 square feet of club amenities run through The Related Life. Buyers comparing the two are weighing a completed building against new construction with projected 2027 delivery.
Related and RAMSA have built 17 buildings together over more than two decades. At 108 units across two towers, the building has fewer residences than several other new high-rises in the city. Full-floor penthouses overlap in price with single-family estates in Palm Beach, so buyers at that level should compare both. See all new developments for side-by-side data, or contact us for a comparison.
Florida has no state income tax. A buyer who moves domicile from New York, California, Connecticut or New Jersey stops paying state tax on income, including capital gains and investment income. The saving depends on the buyer’s income, not on the price of the residence. Property tax in Palm Beach County is set by the combined county, city and school millage. New construction is usually assessed at or near the purchase price in the first year, so the first bill on a large residence is meaningful.
The homestead exemption for primary residents caps annual assessed value increases at 3% and cuts taxable value by $50,000. Buyers from other states should also note Florida’s documentary stamp tax at closing, the intangible tax on mortgages and the absence of a state estate tax. A tax advisor experienced in interstate moves should review the position before closing. Contact us for referrals.
South Flagler House’s rental framework is established in the declaration of covenants filed by Related Ross prior to association turnover. Specific rental restrictions, including minimum lease terms and any initial owner-occupancy requirements, should be confirmed directly with the developer’s sales team or reviewed in the offering documents.
New luxury condominium developments in Palm Beach County typically impose minimum lease terms of six months to one year, with some restricting rentals entirely during the first one to two years of ownership. Buildings at this price tier tend to attract primarily owner-occupants, though some buyers acquire units for seasonal or part-time use with the option to lease during off-seasons.
Buyers considering South Flagler House as a partial investment should model the carrying costs (including HOA assessments, property taxes, and insurance) against realistic rental income for the submarket. Our advisory team can provide market data on rental performance for comparable waterfront and new development residences in the area.
No resale record exists yet, because the building has not delivered. Resale will depend on market conditions, absorption at delivery and the specific unit and floor. Related and RAMSA have completed 17 buildings together. Their Manhattan buildings, 15 Central Park West and 220 Central Park South, have an established resale market, though Manhattan differs from South Florida. Buyers in the secondary market usually value Intracoastal frontage and a low unit count, and South Flagler House has both, but neither guarantees appreciation.
Developable waterfront sites on Flagler Drive are few, which limits direct competition in the corridor, while the wider county pipeline will compete for the same buyers. New condominiums in Florida usually go through two or three years of price discovery after delivery as resales establish comparables. Buyers should set their hold period and carrying costs with that in mind. Contact us for resale data across West Palm Beach waterfront properties.
