Two houses on South Hibiscus Drive face Biscayne Bay with almost the same amount of shoreline. 370 South Hibiscus has 122 feet of waterfront on half an acre. 270 South Hibiscus sits on two combined bayfront lots with 120 feet of frontage. Since mid-2025 both have sold, and the prices are $19.7 million apart.
Two feet of frontage can't account for a gap that size, and the clearest difference between the houses is that they were finished ten years apart. On this island, a house built in 2016 already prices as the previous generation, and buyers are paying a large premium for the years it takes to produce a new one.
| 370 South Hibiscus Drive | 270 South Hibiscus Drive | |
|---|---|---|
| Year completed | 2016 | 2026 |
| Living area | 10,800 sq. ft. | 9,100 sq. ft. |
| Bay frontage | 122 feet | 120 feet |
| Asking price | $37.5 million | $55 million |
| Sale price | $31.8 million, July 2025 | $51.5 million, August 2026 |
| Time to sell | About eight months | 11 days |
| Approx. price per sq. ft. | About $2,940 | About $5,660 |
The older house had more interior space and slightly more water, and it sold for about half as much per square foot. It also took longer to sell and closed further below its asking price.
A shell bought in 2021, a record in 2026
The story of 270 South Hibiscus shows where that value comes from. The Real Deal reported that a joint venture led by Luis Bosch, founder of Luis Bosch Luxury Homes, paid $19 million in 2021 for the property as an unfinished shell. Bosch then oversaw a redesign by the South African firm SAOTA, with interiors by ARRCC and landscape architecture by Raymond Jungles. The finished five-bedroom house has an office, a fitness center, a nightclub, a pool and two docks that fit a yacht up to 105 feet.
The New York Post reported that the house was finished in 2026, listed at $55 million in mid-August, and sold 11 days later for $51.5 million. That set a new record for Hibiscus and Palm islands. The previous high was $40.3 million in 2024 for 101 North Hibiscus Drive, a 10,800-square-foot house sold by a company managed by builder Paul Vogele, who had lived there.
Between the shell purchase and the closing, the venture's buy-in grew from $19 million to $51.5 million in five years. Construction costs come out of that gap, and the time does too. A buyer in 2026 who wanted a new house on this block had two options. They could buy one already built, or they could start the five-year process themselves.
The house that was new in 2016
370 South Hibiscus shows the same calculation from the other direction. In July 2025, The Real Deal reported that a trust linked to former Univision CEO Wade Davis sold the house for $31.8 million. It had been listed eight months earlier at $37.5 million. Records cited in that report show the house was bought for $26.5 million in 2021.
So the 2016 house gained about 20 percent over four years. In roughly the same period, the 2021 shell on the same street almost tripled. The listing agent explained the difference in the same Real Deal article, calling the island "a sort of transitioning neighborhood" where "everybody wants new product. They don't want to have to do any work."
A home completed in 2016 is far from worn out, but on Hibiscus it now competes against houses that are just being finished. The buyer pool at the top of the island's market is paying for a brand-new house, and a ten-year-old one doesn't qualify.
How a vacant lot becomes a $42 million ask
The third data point is on North Hibiscus Drive, and it shows each step in the process with a price attached.
- 2022, first purchase. Miami investor Laurent Groll and partners bought a 0.4-acre lot for $10.7 million, planning a spec home using designs by architect Kobi Karp.
- About a month later. They resold the lot for $14 million to a buyer who went ahead with Karp's design.
- Design and build. Karp worked with the European firm AED Planung on interiors. The result is a house of almost 7,900 square feet with 90 feet of bulkheaded waterfront and a dock with lifts for several boats.
- September 2026. The finished house was asking $42 million when Robb Report featured it.
That ask is about $5,300 per square foot on a lot with 32 fewer feet of frontage than 370 South Hibiscus, which sold in 2025 for about $2,940 per square foot. The land under the Karp house cost $14 million at its second sale. Most of the rest of the asking price is for a finished new house and the four years it took to deliver it.
Taken together, the three properties show a consistent pattern. A buyer can get land and water on Hibiscus at one price, and a finished new house costs a very different one. The gap between the two keeps widening, because so few new houses come to market and each takes years to finish.
Why the supply of new houses stays thin
Miami Beach places few barriers in front of a teardown. In 2022, the Miami Herald reported that Miami Beach's Design Review Board reviewed demolition requests for architecturally significant single-family homes built before 1942, but it could only try to persuade owners to preserve them, not stop the demolition. One of the Herald's examples was a 1937 Hibiscus Island villa designed by August Geiger. City planners had flagged it as architecturally significant, and it received a demolition permit in 2019 so a larger contemporary house could replace it.
Since that report, the rules have relaxed further. A May 28, 2024 Miami Beach Planning Department staff report explains that Florida's HB 423, effective July 1, 2022, preempts local rules on demolishing single-family homes whose lowest finished floor is below base flood elevation plus one foot. Homes designated historic before January 1, 2022 are the one exception to that preemption. For homes the preemption does cover, Design Review Board review of the replacement house is no longer mandatory unless the project includes an understory, seeks a design waiver or variance, or involves a lot split. The same report says that when the city adopted its Resiliency Code in 2023, it removed the old penalties that capped lot coverage at 25 percent and unit size at 40 percent when an architecturally significant pre-1942 home was demolished on lots being divided. The Planning Board can still set size limits when lots are subdivided.
Whether any of this applies to a particular address depends on that home's age, elevation, designation and the project planned for it. This post is general information, not legal advice, so anyone considering a teardown should confirm the details with a land-use attorney and the city's planning staff.
So the bottleneck is how long construction takes. The 270 South Hibiscus team started with a shell and still needed about five years. The Karp house took about four years from lot to listing. Even with the rules easing, the supply of new houses grows only as fast as those projects can be finished.
What this means when you compare two Hibiscus listings
Most of the price difference between two homes on the island reflects their completion dates. For a buyer, that affects three things.
- A resale home from the last 10 to 15 years is priced closer to the land beneath it plus a discounted house. In 2025, 370 South Hibiscus sold below its ask after eight months, which suggests that buyers of homes like it have some room to negotiate.
- A just-completed home is priced for the time someone else spent building it. 270 South Hibiscus sold within about 6 percent of its ask in 11 days.
- A shell or lot costs the least up front and asks the most patience. The 2021 and 2022 examples above show that turning one into a finished house took four to five years.
Each of these trades price against time in a different way.
FAQ
Does more waterfront mean a higher price on Hibiscus Island? Not on its own. The two South Hibiscus Drive sales had nearly identical frontage, 122 and 120 feet, and sold about $19.7 million apart. The Karp-designed house on North Hibiscus has 90 feet and was asking $42 million in September 2026, about $10 million more than 370 South Hibiscus sold for.
What is the current sales record on Hibiscus Island? As of the August 2026 sale, the record is $51.5 million for 270 South Hibiscus Drive. The Real Deal reported that it also set the per-square-foot record for Hibiscus and Palm islands.
Can an older Hibiscus Island home be demolished? The city's 2024 staff report describes a state preemption that covers many single-family homes, with exceptions for homes designated historic before January 1, 2022. The answer depends on the specific property, so confirm it with the city and your own counsel.
If you're weighing a finished Hibiscus Island home against an older house you'd remodel or rebuild, the decision usually comes down to how many years you're willing to wait.
