South Flagler House: Prices, Floor Plans & Available Units

West Palm Beach spent a decade as the affordable side of the bridge. That is over. The waterfront strip along South Flagler Drive now carries the highest-priced new condominium inventory in Palm Beach County, and South Flagler House is the project that set the ceiling. According to PROFILEmiami, Related Ross celebrated the topping-out of the Robert A.M. Stern Architects-designed building in November 2025, one year after vertical construction began, with 105 two- to five-bedroom residences split across a North and a South tower and residents expected in 2027.

Florida YIMBY reported the same milestone at 1355 South Flagler Drive and has tracked the project since a $600 million construction loan closed in June 2025. Coastal Construction is the general contractor and Pembrooke & Ives handled interiors. For a buyer, the topping-out is the fact that matters most on this page. A pre-construction contract signed against a building that is already structurally complete carries a very different delivery risk than one signed against a rendering and a permit, and that difference should show up in how you think about your deposit ladder.

The unusual thing about how Related Ross sells this building is the transparency of the pricing. Most developers publish a single "from" number and make you call for the rest. The developer residences page instead publishes four separate floor bands with their own bedroom counts, square footage ranges and price ranges. Floors 5 to 9 hold one- to four-bedroom homes and owner guest suites of roughly 854 to 5,385 square feet at $16,650,000 to $23,500,000. The Signature Residences on floors 10 to 18 are two to four bedrooms, 2,592 to 5,173 square feet, at $7,980,000 to $34,500,000. Floors 19 and 20 run three to four bedrooms, 4,864 to 5,946 square feet, at $21,250,000 to $29,175,000. The penthouse collection on floors 25 to 28, four full-floor homes plus one duplex, runs 9,743 to 14,053 square feet at $49,500,000 to $70,000,000.

Read those bands together and one thing jumps out. When PROFILEmiami reported the topping-out in November 2025, the published range opened at $6 million. Today the lowest published band starts at $7,980,000. The entry point has moved up roughly a third in nine months as inventory sold, which is the clearest evidence I can give you that the trophy end of this market is behaving very differently from the generic mid-tier. It also means the "from" price you read in an older article is no longer the price you can buy at, and you should treat any secondhand number on this building as stale until someone checks the current sheet.

The amenity program runs to 50,000 square feet of private club space, per the developer amenities page. The headline pieces are a 25-meter lap pool with a sun shelf, hot tub and poolside cabanas, separate men's and women's spas each with a vitality pool, ice plunge, steam room and sauna, a fitness center with dedicated yoga and Pilates studios, a pickleball court and lounge, a sports simulator lounge with an indoor practice green, and a residents-only indoor and outdoor restaurant with private dining rooms and a wine tasting room. There is a business center with private offices and indoor and outdoor conference rooms, a theater, a games room, a children's playroom and craft room, and an outdoor butterfly garden.

Two programs sit alongside the building itself and both are worth asking about before you sign. Rogers by Related Ross, built with Rogers General Contracting, lets a buyer commission a fully custom home delivered turnkey at closing, with customization beginning before closing. Artisan Home is a separate membership covering post-closing alterations, vendor coordination, permits and HOA approvals, twice-yearly walkthroughs and preventative maintenance checks. Neither is automatically included in the purchase price, and I would want that clarified in writing rather than assumed. Call me at 305-964-8614 or use the contact page and I will pull the current band pricing, tell you which stacks face the Lake versus the city, and line this up against the other Palm Beach County waterfront launches so you are comparing like for like.
