A New York family agreed to pay $47 million for The Charles penthouse at St. Regis Residences Brickell, about $4,694 per square foot, according to Realtor.com. What matters to me is that this is a pre-construction contract on a tower that does not deliver until 2027. Buyers chasing this tier should price the delivery risk, not last week's headline.
Two Brickell penthouse records inside five months is not a market doing anything by accident. A New York family agreed to buy The Charles, the two-floor top residence at St. Regis Residences on Brickell Avenue, for $47 million, according to Realtor.com. That works out to roughly $4,694 per square foot across 10,012 square feet, and it lands just under the $49.9 million paid in March for each of a pair of duplex penthouses at the Residences at Mandarin Oriental. The trophy number is not the interesting part. What a contract like this says about supply, timing and who is writing the checks in Brickell pre-construction is.
What $47 Million Buys at 1809 Brickell Avenue
The Charles spans 10,012 square feet over two floors, with five bedrooms, seven bathrooms, two terraces, a private rooftop pool, a spa and a summer kitchen, per Realtor.com. It sits at the top of a 50-story tower on Brickell Avenue overlooking Biscayne Bay, scheduled for completion at the end of 2027. Related Group is developing it with Integra Investments, and Robert A.M. Stern Architects handled the design.
The building holds 152 residences with prices starting above $5 million. Developers report more than 80 percent sold, representing roughly $900 million against a sellout approaching $1 billion. That absorption number is the one I would underline: a tower this expensive clearing four fifths of its inventory before topping out tells you the demand is not speculative froth arriving late, it has been there the whole cycle.
Anyone comparing this to the rest of the building should start with the floor and the line rather than the brand. A top-floor duplex with a private pool is a one-off product inside a 152-unit tower, and its price per foot does not set the number for a standard high-floor residence downstairs. Our breakdown of pricing across the St. Regis Brickell stack shows how wide that spread runs.
Why Brickell Is Where the Ceiling Moved
Brickell historically did not set the top of the South Florida market. Miami Beach and Fisher Island did. What changed is the buyer. Greater Miami has recorded 24 home sales above $30 million so far in 2026, against two in all of 2019, according to Bloomberg. The developer says the St. Regis buyer pool started roughly half foreign and half domestic, and recent contracts skew heavily toward the northeastern United States.
That shift explains the location. A buyer relocating from New York for tax reasons wants offices, restaurants and schools within a few blocks, not a barrier island. Florida has no state income tax, New York is rolling out a levy on highly valued second homes, and Brickell is the one Miami submarket that reads as an urban neighborhood rather than a resort. Related's condominium division president has said these buyers plan to live here a substantial part of the year rather than leave the unit empty.
| Contract | Price | Detail |
|---|---|---|
| Residences at Mandarin Oriental | $49.9M each | Pair of duplex penthouses, under contract March 2026 |
| St. Regis Residences, The Charles | $47M | 10,012 sq ft over two floors, reported July 31, 2026 |
| St. Regis entry pricing | From $5M+ | 152 residences total, more than 80 percent sold |
| Miami metro luxury median | $4,855,331 | Three months ending May 2026, up 14.2 percent year over year |
Set against that median, a $47 million contract is close to ten times the typical Miami luxury sale. The gap is the point: the top of this market is not moving with the rest of it. Anyone benchmarking a purchase against the Mandarin Oriental tower or the St. Regis is pricing a segment with its own supply curve.
The Supply Math Behind a $4.86 Million Median
The trophy contracts are downstream of a supply problem. Miami's median luxury sale price hit $4,855,331 in the three months ending May 2026, up 14.2 percent year over year, the second-largest gain of any major U.S. metro, according to Redfin. Over the same window, new luxury listings fell 13 percent and active luxury inventory dropped 17.2 percent, the steepest decline Redfin measured anywhere.
Demand rose into that. Pending luxury sales climbed 14.6 percent and closed sales rose 5.2 percent. When inventory contracts by a sixth while pending sales grow by a seventh, price is the only variable left to move.
One number cuts against the momentum story, and I think it is the most useful figure in the dataset. Miami luxury homes sat a median of 150 days before going under contract, 24 days longer than the prior year and the longest wait of any major metro Redfin tracked. That is not weak demand. At a near-$5 million median the buyer pool is smaller and due diligence takes longer. Sellers at this tier are getting their price, just not getting it quickly.
Here is what I would weigh before treating a headline contract as a signal for your own purchase:
- A penthouse price is not a building price: $4,694 per square foot is a top-floor duplex number. Standard high-floor residences in the same tower trade well below it, and the spread widens as you go down the stack.
- Delivery is 2027: Every contract signed today at St. Regis Brickell is an unbuilt product. Read the completion clause and the developer's delivery history before you read the renderings.
- Deposit schedule is the real commitment: Miami pre-construction typically calls for staged deposits well before delivery. Model the cash-out timeline, not just the purchase price.
- 150 days is the honest liquidity number: If you may need to exit inside two years, price that median marketing time into your decision now.
- Compare branded towers directly: Our side-by-side of the three flagship branded towers lays out where each one actually differs on price, amenities and delivery.
For buyers outside the United States, none of this changes the ownership structure questions, only the timing. Work the entity and financing decisions first, then the unit.
How I Underwrite a Pre-Construction Penthouse Contract
My advice on contracts at this tier is to underwrite the calendar before the price. A $47 million signature on a tower delivering in late 2027 means the buyer is holding a position for roughly 17 months against a market that has already run 14 percent in a year. If the top of the Miami market flattens between now and then, the contract price does not adjust. That risk sits entirely with the buyer, and it is the single thing I make sure a client can absorb before we talk about views.
The second thing I look at is the developer's completion record, not the brand on the door. A hotel name licenses its standards; it does not build the building or guarantee the delivery date. I want to know what the same sponsor delivered last cycle and how close it landed to the announced date. That history is knowable, and it is worth more than any rendering.
Third is the floor and the line. The thing I tell buyers about branded towers is that the premium is real but uneven: it concentrates in the corner lines and the top third, and it thins out fast in interior units where you are paying brand pricing for a standard layout. A headline penthouse number does not set the price for the stack below it.
Fourth is what happens after delivery. The pre-construction buying process guide covers the deposit schedule you commit to before a shovel moves, and the true cost of owning guide covers the carrying costs that arrive with the keys. At this size the annual carry is its own significant number, and buyers underestimate it more often than the purchase price.
"A record price on an unbuilt tower is a bet on a delivery date, not a valuation. Underwrite the 2027 calendar first, then decide what the view is worth."
The $47 million number will travel much further than the details underneath it, which is why the details are the part worth keeping. This is a pre-construction contract on a tower that does not deliver until the end of 2027, in a metro where luxury inventory has fallen 17.2 percent and the median luxury home still takes 150 days to go under contract. Those facts describe a market where the very top is tight while the transaction itself stays slow. The useful question is not whether Brickell can support a $47 million penthouse. It clearly can. It is whether your own timeline survives a 2027 delivery date.
