An island beach or the island view

OLIN Palm Beach is OKO Group and Cain International's three five-story buildings at 2720 and 2730 South Ocean Boulevard, the first new condominium on Palm Beach island since 2006, with 32 residences offered in bands from under $20 million to over $40 million and no published delivery date. South Flagler House is Related Ross's pair of 28-story Stern towers on the West Palm shore, topped out, delivering in 2027, with residences from about $5.7 million and penthouses asked near $70 million.

Where each one wins
OLIN is the rarer thing: an ocean beach, an island address and a five-story building that will never be overshadowed, because the town's code will not allow it. It is also the less certain thing, with no date, no price list and a demolition that only began in July 2026.
South Flagler House is the certain thing: you can see it, you can price it and you will close in 2027. Its view is of the island rather than from it, and the towers beside it will be under construction for years.
Choose OLIN Palm Beach if
- You want the beach and the town of Palm Beach itself
- Low-rise, private, and OMA matter more than a date
- Your budget starts above $20 million
Choose South Flagler House if
- You want to close in 2027
- The lagoon view of the estate section is the view you want
- A 105-residence club suits you better than 32 neighbors
Where each one sits
