South Flagler House vs Edgeworth West Palm Beach: two Related Ross towers on the same shore
South Flagler House vs Edgeworth compares two Related Ross condominiums on adjoining South Flagler Drive sites: a topped-out limestone pair by Robert A.M. Stern and a curved pair by Kohn Pedersen Fox that has not broken ground. Timing, title and amenity scale separate them more than the entry price does.

The short answer
- Both towers are Related Ross projects sold by the same team from the same gallery, so the choice is one of product and timing rather than developer.
- South Flagler House is topped out and sells in bands from $6 million to $8 million upward; Edgeworth quotes from $5.5 million and has not started construction.
- Edgeworth sits on a 99-year ground lease from Family Church, while South Flagler House stands on land Related bought outright.
- Edgeworth promises more than 90,000 square feet of amenities, close to double the roughly 50,000-square-foot club at South Flagler House, spread over more owners.
- Both parcels lie in FEMA Zone AE at an 8-foot base flood elevation and carry the same West Palm Beach tax stack.

South Flagler House vs Edgeworth in brief
South Flagler House vs Edgeworth is a choice between Related Ross condominiums on adjoining South Flagler Drive sites. South Flagler House at 1355 South Flagler Drive is topped out, with 105 residences selling in bands from $6 million to $8 million. Edgeworth at 1155 South Flagler Drive is in pre-sales from $5.5 million, and construction is expected to begin in 2027.
The two buildings share more than a developer. Adam McPherson of Related Ross leads sales at both, with Corcoran Sunshine Marketing Group alongside him at Edgeworth and Suzanne Frisbie of The Corcoran Group at South Flagler House. Frisbie Group sold the South Flagler House land to Related in 2023 and is Related's partner on the Edgeworth ground lease. The Edgeworth gallery is at 616 Hibiscus Street downtown.
The differences are architectural and legal. South Flagler House is a pair of 28-story Robert A.M. Stern Architects towers in a pre-war New York idiom. Coastal Construction is building it on about 3.4 acres Related bought for a recorded $194.6 million. Edgeworth is two curved 28-story Kohn Pedersen Fox towers planned for the southern 4.6 acres of the Family Church campus, on land the church is leasing for 99 years.
South Flagler House and Edgeworth prices and price per square foot
South Flagler House quotes in bands, and the published figures do not agree. The official inquiry form runs from $6 million to $8 million up to $20 million to $30 million. Haute Residence lists entry near $5.7 million and available non-penthouse homes from $5.7 million to $29.2 million. The top-off release cited availability from $6 million to $72.5 million.
Per-foot arithmetic at the entry depends on the plan quoted. If the $5.7 million entry is the smallest signature residence of 2,592 square feet, it works out to about $2,200 a square foot. At the top, a South Tower duplex penthouse of 13,904 square feet was listed in June 2026 at $70 million, about $5,030 a square foot. The developer publishes no price per foot, so the live sheet is the number to rely on, not a tracker.
Former Apple chief executive John Sculley was reported to have contracted a penthouse near $40 million. Related Ross reported more than $500 million in pre-construction sales in the first quarter of 2026 alone. Edgeworth launched in March 2026 at $2.5 million to $35.5 million, and the lower figure appears to have reflected 1-bedroom plans the site no longer offers.
The official Edgeworth site and Related Ross's property page now quote from $5.5 million, and Haute Residence lists $5.3 million to $35.5 million. Residence sizes are unpublished, so no per-foot comparison is possible yet. The nearest finished reference is Forté on Flagler next door, where two half-floor homes of about 4,440 square feet closed in September 2026 at $10.2 million each, near $2,300 a square foot.
Edgeworth is denser and still open to choice of stack
South Flagler House stacks three products. Floors 5 through 9 hold 1-bedroom owner guest suites, and floors 10 through 18 the signature residences of 2 to 4 bedrooms, from 2,592 to 5,173 square feet. The penthouses on floors 25 through 28 run from 9,743 to 14,053 square feet.
Those penthouses are large enough that the city changed its zoning in March 2025 to allow two full kitchens in one dwelling, a change requested for this building. Related has not published a per-floor count. Its 105 homes across two towers imply a low average per floor, with fewer homes on the penthouse floors and more on the guest-suite floors.
Edgeworth is denser on paper. The official site lists 184 residences of 2 to 4 bedrooms across two 28-story towers with 9 penthouses, roughly 3 to 4 homes per residential floor. Every residence has a private elevator, rather than only the upper floors. Counts conflict: the launch release said 168, and trackers say 190 in towers of 28 and 32 stories.
A Planning Board amendment in October 2025 reportedly equalized the towers near 30 stories, so the recorded site plan sets the count, not the brochure. The practical difference is choice. South Flagler House has sold through most of its program, and remaining selection lies in specific lines and floors. Edgeworth is early enough to pick exposure and stack, at the cost of waiting for a building that exists only as drawings.
Edgeworth nearly doubles the club and spreads it over more owners
The South Flagler House club covers about 50,000 square feet on three floors. It holds a 25-meter lakefront lap pool with cabanas, his-and-hers spas with hydrotherapy, a salon, fitness and pilates studios and a golf simulator lounge. An indoor pickleball court, a theater, a wine room and private dining follow, with three culinary concepts. The first, Tutto Caffe, was announced in September 2026, and interiors are by Pembrooke & Ives.
Edgeworth promises more than 90,000 square feet, with the full list still to be revealed. Confirmed so far are a vitality pool and cold plunge, lap and leisure pools on a resort deck and a racquet club. A spa and fitness program with Bradford Wellness as partner, a private arrival court and a residents' lounge complete it. Interiors are by MAWD and landscape by DS Boca.
Scale cuts both ways. A racquet club and a spa of that size are real daily advantages for a household that will use them. They are also fixed costs carried by 184 owners rather than 105, and neither developer has published an operating budget.
Brokers estimate South Flagler House dues near $2.12 a square foot a month, and there is no Edgeworth estimate yet. The True cost of ownership tool on this site runs taxes, dues and insurance side by side once the estimated budget is in hand.
Read the Edgeworth ground lease before the deposit
The ground lease is the largest structural difference between the two. Family Church is leasing about 4.6 of its 9.7 acres for 99 years in a deal reported near $100 million, and the proceeds fund a new 4-story school on the rest of the campus. South Flagler House is fee simple on land Related owns.
Edgeworth is therefore a leasehold condominium with a very long but finite term. Lenders and title insurers handle leaseholds routinely in Florida. The rent schedule, escalations and reversion still belong in a lawyer's review before a deposit is paid. Neither building has published a deposit schedule.
The South Flagler House sales team says terms are not published, and Edgeworth's trackers say schedules are available on request. Under section 718.202, deposits up to 10 percent of the price must be held in escrow. Amounts above that may fund construction only if the contract allows it and the statute's conditions are met. Section 718.503 gives a 15-day cancellation right after signing or receipt of the required documents.
The Deposit planner on this site sets any gallery schedule against those rules. Taxes are identical in rate: both parcels carry the 2025 West Palm Beach stack of 20.4468 mills. A $6 million residence assessed at full value pays about $122,700 a year before homestead, and a $5.5 million residence about $112,500. Both sites lie in FEMA Zone AE with a base flood elevation of 8 feet NAVD88, with a VE strip at the seawall at South Flagler House.
The 1100 and 1300 blocks deliver about 2 years apart
South Flagler House broke ground on April 17, 2024, topped out both towers in November 2025 and is now in fit-out. The developer says residents move in during 2027, and one tracker narrows that to the third quarter. A $600 million construction loan was reported in mid-2025. At this stage, delays tend to be measured in months.
Edgeworth has announced no construction loan or groundbreaking. A March 2026 report expected construction to start in 2027 and take about 2 years, and one tracker lists the fourth quarter of 2029. The Family Church planned development was filed in April 2024, and the Planning Board recommended an amendment in October 2025. A final City Commission vote could not be confirmed in the sources opened for this article, so the recorded approval should come from the sales team.
The two sites will affect each other. North-facing homes at South Flagler House will look at an active construction site for roughly 2 years after their owners close. Edgeworth buyers will move into a finished block, with South Flagler House complete to the south and the Bristol and Trianon to the north.
Timing and title decide between the two towers
South Flagler House suits a buyer who wants to close within about a year and prefers classical architecture with a fee-simple title. It also suits a household that may need a guest suite in the same building for family or staff. Its remaining choice is narrower, and its pricing reflects certainty.
Edgeworth suits a buyer for whom price per square foot is the first filter and who will use a racquet club and a large spa daily. That buyer must be able to hold deposits until 2029 and accept a leasehold after counsel has read it. A Premier Listings advisor can arrange a private viewing of both programs from the Hibiscus Street gallery in a single appointment.
