A Sequel Before the Premiere
Edgeworth arrived by press release on March 16, 2026, with an official site and a sales gallery run by Corcoran Sunshine. The filing line is simple to state. Kohn Pedersen Fox designs the two towers, March and White Design handles the interiors, and the 168 residences span one to five bedrooms, nine of them penthouses. Pricing was reported from $2.5M to $35.5M at launch. Construction is planned to start in 2027, with completion targeted for 2029.
The address carries the real news. The site sits at 1155 South Flagler Drive, sharing a property line with South Flagler House, the developer's 108 residence flagship that delivers in 2027. One company now controls back to back addresses on the city's most watched waterfront stretch, a position our study of the drive examines in full.

What the Sequel Changes
A sequel gets to revise, and Edgeworth revises plenty. The architecture moves from Robert A.M. Stern's limestone classicism to Kohn Pedersen Fox, a modernist hand. The residence count grows from 108 to 168, so the towers slice into more and smaller homes. The private elevator, an arrival the flagship offers behind an $8.55M open floor, now reaches every home down to the $2.5M reported entry. And the shared amenity program steps up to a stated 90,000 plus square feet, against roughly 50,000 square feet of club floors next door.

The $2.5M Door
The lowest rung is the sharpest change. South Flagler House opens at $8.55M on its current asking ladder, so the flagship never meets the buyer with $3M to spend. Edgeworth does, at roughly a third of the neighboring entry, and its one bedroom lines mark the first time this developer has offered the drive at that scale. The reported range still climbs to $35.5M, so the sequel keeps a penthouse book while opening the door far wider at the bottom.
What Building Beside Your Flagship Signals
Developers rarely launch beside their own unfinished project, because the second book competes with the first. Doing it anyway signals confidence in the order at hand. A company does not queue 168 more residences behind 108 unsold ones, so the launch reads as public evidence of how the flagship's contract book stands. The pricing signals discipline too. Edgeworth undercuts the flagship's floor without touching its crown, which lets the pair cover the market from $2.5M to $70M with no rung contested between them.

What to Watch Next
Every figure above is a published number, and no closing has recorded at either address. Three markers will test the sequel. Watch whether the reported range holds through the first releases, since preconstruction books move with demand. Watch the 2027 groundbreaking date, the first hard promise on the calendar. And watch the flagship's first recorded closings after its 2027 delivery, because those deeds will price the ground the sequel stands on. The county pipeline page tracks all three.

Bottom Line
Edgeworth is Related Ross revising its own hit while the original is still in previews. The revisions run deep: more residences, a modernist hand, a private elevator at every price, and an entry near a third of the flagship's open floor. The launch itself is the tell. A developer extends a street only when the first book has earned it.
For a buyer watching the drive: Ask us for both books side by side, the flagship's open lines and Edgeworth's releases as they open. The gap between the two entries is where the early decisions get made.
Edgeworth facts follow the developer's published materials as of March 2026, including the official site and the March 16, 2026 release, and are subject to change. The residence count of 168 is the developer's figure. Press coverage at launch reported 164, and the developer count governs here. Pricing of $2.5M to $35.5M is the reported launch range, not a recorded sale, and no closing has recorded at Edgeworth or South Flagler House. South Flagler House figures are the building's open asking lines in August 2026, per our asking-ladder study. Building details are the developer's published materials as of August 2026, subject to change.
