Edgeworth rises at 1155 S Flagler Drive in West Palm Beach, next door to South Flagler House. Related Ross stands behind both, which turns two neighboring addresses into one developer's statement on the corridor.
The pairing matters for buyers. The same developer answers for the street on both sides of the property line, and the two sales processes will run within sight of each other.
The first bet is privacy at scale. Every residence arrives by its own private elevator, set above more than 90,000 square feet of shared amenities.
The second bet is the corridor itself. Rather than plant a flag in a new district, Related Ross is adding a second address on the same stretch of S Flagler Drive it already builds on.
