South Flagler House by Related Ross and Robert A.M. Stern. 108 residences from $6M across two 28-story towers on South Flagler Drive. 2027 delivery.
Project Overview
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, with more than $70 billion in assets owned or under development. 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.

The Team
Stephen M. Ross founded Related Companies in 1972, building it into a global real estate firm with over $70 billion in assets owned or under development. His largest completed project is Hudson Yards in Manhattan (the largest private real estate development in U.S. history). Related also developed Time Warner Center.
In 2024, Ross founded Related Ross to focus on South Florida development. Related Companies is the largest commercial property owner in downtown West Palm Beach. South Flagler House is Related’s first luxury residential condominium in Florida. Ross is also the principal owner of the Miami Dolphins.
Robert A.M. Stern Architects (RAMSA) is an international architecture practice known for contextual residential design. The firm’s long-standing partnership with Related Companies includes 17 buildings across the country, among them 15 Central Park West and 220 Central Park South.
South Flagler House is RAMSA’s first luxury residential high-rise in Florida. The design draws from the architectural vocabulary of Palm Beach’s 1930s-era buildings, adapted to the property’s Intracoastal Waterway frontage in West Palm Beach.

Common Questions
Residences at South Flagler House were originally priced from approximately $5.9 million to $72.5 million at the 2023 sales launch. As lower-priced units have sold, current availability begins at approximately $7.9 million, with penthouses priced up to $73 million. 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, ranging from 5,500 to 6,450 square feet, begin around $25 million.
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 reached their final height of 28 stories when construction topped off in November 2025. Interior finishing and amenity buildout are the remaining phases before certificate of occupancy.
Related Companies’ portfolio includes Hudson Yards in Manhattan, the largest private real estate development in U.S. history. The South Flagler House timeline has progressed through each milestone on pace since the $194.6 million site acquisition in August 2023.
Buyers evaluating under-construction purchases in the Palm Beach County new development market should weigh each project’s stage against its deposit structure and closing timeline. For guidance on comparable new construction properties, contact our advisory team.

Related Ross, the South Florida development 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, with more than $70 billion in assets owned or under development. His portfolio includes Hudson Yards in Manhattan (the largest private real estate development in U.S. history) and the 72-acre CityPlace redevelopment in West Palm Beach.
Related Companies is the largest commercial property owner in downtown West Palm Beach. Robert A.M. Stern Architects (RAMSA) designed the building. The Related-RAMSA partnership spans more than two decades and 17 buildings nationwide, including 15 Central Park West and 220 Central Park South in Manhattan. South Flagler House is the partnership’s first residential project in Florida.
Interior design is by Pembrooke & Ives, and landscape architecture by SMI Landscape Architecture. For buyers evaluating developer portfolios across Palm Beach County new developments and condominiums, contact our advisory team for building-by-building comparisons.
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 typically carry monthly assessments in the range of $2.50 to $4.00 per square foot, depending on 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 (RAMSA), with construction by Coastal Construction, the largest general contractor in South Florida. RAMSA’s residential portfolio includes 15 Central Park West and 220 Central Park South in Manhattan. South Flagler House is RAMSA’s first luxury residential high-rise in Florida.
The building is designed to current Florida Building Code standards, which are among the most stringent in the country for wind resistance and flood mitigation. Residences are delivered with interior 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 across all residences.
The twin-tower design, with the Lake Tower and Park Tower arranged around a central landscaped motor court, provides multiple exposures and cross-ventilation. Full-floor penthouses are delivered as custom builds by Rogers, a firm specializing in high-end residential construction. For buyers comparing construction specifications across new developments and condominiums in West Palm Beach, our team provides building-by-building analysis.
Residences are priced from approximately $6 million to $73 million, placing the building at the upper end of the West Palm Beach condominium market by asking price. The building competes most directly with other waterfront high-rises along the Flagler Drive corridor, though its price ceiling exceeds most current local inventory.
South Flagler House competes most directly with The Bristol (69 residences, completed 2019, also on South Flagler Drive). Both buildings were designed by Robert A.M. Stern Architects. The Bristol established the $10M+ per-unit benchmark for the corridor; South Flagler House extends the price ceiling to $73M with larger floor plans, twin-tower scale, and 50,000 SF of private club amenities operated through The Related Life platform. Buyers cross-shopping the two buildings are comparing completed, move-in-ready residences at The Bristol against new construction with 2027 delivery at South Flagler House.
The Related-RAMSA partnership is the only developer-architect team in the West Palm Beach pipeline with a multi-decade, multi-building collaboration of this scale. At 108 units across two towers, the building has a lower unit count than several other new high-rises in the market.
Buyers should evaluate South Flagler House against both the West Palm Beach new development pipeline and resale inventory on Palm Beach Island. At the upper end of the price range, full-floor penthouses overlap in price with single-family estate properties in Palm Beach. See all new developments for side-by-side data, or contact our advisory team for a tailored comparison.
At South Flagler House’s price tier, Florida’s zero state income tax has an outsized impact. A buyer relocating from New York, California, Connecticut, or New Jersey eliminates state tax on all income sources, including capital gains and investment income. On a $20M+ purchase, the annual tax savings from domicile change alone can exceed six figures.
Property taxes in Palm Beach County are assessed at the combined county, city, and school district millage rate. New construction is typically assessed at or near purchase price in the first year, which can result in a meaningful initial tax liability for higher-priced residences. Florida’s homestead exemption (available to primary residents) caps annual assessed value increases at 3% and provides a $50,000 reduction in taxable value.
Buyers relocating from other states should also evaluate Florida’s documentary stamp tax (applied at closing), intangible tax on mortgages, and the absence of state estate tax. A tax advisor experienced in interstate relocations is recommended before closing. For a broader view of tax considerations affecting waterfront property and condominium purchases in Palm Beach County, contact our advisory team.
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.
Resale performance will depend on broader market conditions, absorption rate at delivery, and the specific unit and floor. Several factors are relevant to the analysis. The Related-RAMSA partnership has completed 17 buildings together; their earlier collaborations (15 Central Park West, 220 Central Park South) have traded well on the secondary market, though Manhattan dynamics differ from South Florida. The building’s Intracoastal Waterway frontage and 108-unit density (relatively low for a project of this scale) are characteristics that buyers in the secondary market typically value, but neither guarantees appreciation.
On the supply side, developable waterfront sites along Flagler Drive are limited, which constrains direct future competition in the immediate corridor. However, the broader West Palm Beach and Palm Beach County pipeline includes additional new developments at various price points that will compete for the same buyer pool.
New-construction condominiums in Florida typically experience a period of price discovery in the first two to three years after delivery as the initial sales program concludes and resale transactions establish market comparables. Buyers should evaluate their hold period and carrying costs accordingly. For data on resale trends across waterfront properties in West Palm Beach, consult our seller advisory team.
