01Porsche Design Tower
At Porsche Design Tower the elevator carries residents in their cars, up to garages beside their homes. A turntable aligns the car, a shuttle slides it into the elevator cabin, and the cabin turns to a garage beside the residence, each car directed by its own RFID tag. Dezer Development built the tower with Porsche Design and completed it in 2016, and every one of its 132 residences is served by that system.
For all the engineering, most of its sales sit below $5 million. Between January 2025 and June 2026 the state's 2026 tax roll records 12 arm's-length sales at 18555 Collins Avenue, sales between unrelated parties on market terms, at a median of $4.1 million; only 2 reached $5 million or more. The circular tower stands on the ocean side of the avenue in Sunny Isles Beach, and the state registry records the condominium under its address, 18555 Collins Avenue Condo.

To the south is Turnberry Ocean Club (18501 Collins Avenue), completed in 2020 and 2021. To the north are the Millennium Condo (18671 Collins Avenue), completed in 1999, and then M Resort Residences (18683 Collins Avenue), completed in 2005. The architect gives the site 2.2 acres.
The tower lies in the City of Sunny Isles Beach, Miami-Dade County, a separate city from both Miami and Miami Beach; the city's own operating rate for 2025 was 1.7000 mills. No source used here records which way each floor looks or what it sees.

CTBUH names The Sieger Suarez Architectural Partnership as architect, and the builder credits Porsche Design Studio together with Sieger Suarez; CTBUH lists Studio F. A. Porsche for the interiors. The structure explains the open floors. The tower is circular and all-concrete, with just 12 columns carrying post-tensioned slabs, designed by CHM Structural Engineers with Suncoast Post-Tension on the slab system. Steven Feller P.E. designed the mechanical, electrical and plumbing systems, and Coastal Construction, with EGS2 Corp., was the main contractor.
The developer calls the car elevator the Dezervator, and Mid-American Elevator supplied it. A US patent, 9,765,546 B2, "Passenger and vehicle elevator system", was granted on 19 September 2017; its link to this tower rests on the patent family and press reports. The height depends on the source: CTBUH gives 641 ft (195.4 m) and 57 floors, the architect 58 and the builder 59, and the tower was marketed as 60 stories.
Sieger Suarez also designed Bentley Residences and the Trump Grande complex, and was architect of record for Muse and Residences by Armani/Casa. No source consulted names a landscape architect or states the design idea. Architecture of the coast places this tower among the work of its neighbors' designers.
§ 05Porsche Design Tower
The developer states that every residence has its own two-car garage and private elevator, and that most have a private pool on the balcony. The builder gives residence sizes of 3,500 to 5,000 sq ft (325 to 465 m²) and penthouses of about 15,000 sq ft (1,394 m²). The county records living areas of 3,130 to 8,566 sq ft (291 to 796 m²), with a median of 3,171 sq ft (295 m²); the two are measured under different rules and do not compare directly. Published floor plans were not found in the sources consulted.
Interiors are credited to Studio F. A. Porsche. For shared space, the developer lists a spa with Vichy showers, a sunset terrace with spa tubs, an oceanfront ballroom, and clubrooms with a movie theater and racing and golf simulators. It also names a car concierge and 24-hour valet and security staff. This page describes the building, not any brand's services.

The market has no single definition of a luxury home, so this site draws the line at a recorded sale of $5 million or more. The state's Department of Revenue sorts every recorded deed into arm's-length sales and the rest. Twenty deeds at this address carry 2025 or 2026 dates on the 2026 roll. Thirteen were arm's-length sales; the method sets one aside as an outlier, leaving 12, recorded between January 2025 and June 2026.
01
Median price:
$4.1 million.
02
Range:
$3.2 million to $13.0 million.
03
Sales at $5 million or more:
2, with a median price of $9.075 million and a median of $1,885 per sq ft.
04
Price per square foot:
$1,011 to $2,124 of county-recorded living area (about $10,900 to $22,900 per m²), median $1,214 (about $13,100 per m²).
How these figures compare. Most recorded resales here sit below $5 million. The highest count of arm's-length sales at $5 million or more at a single Sunny Isles Beach condominium address on the 2026 roll was 15. It was recorded next door at Turnberry Ocean Club and at The Estates at Acqualina South Tower. Across the city, 13 condominium addresses recorded at least one such sale, and 18 hold at least one residence valued at $5 million or more.
Sieger Suarez, the architect here, was architect of record for the Residences by Armani/Casa. Price per square foot is the median across all arm's-length sales in each building:
| Building | Sales at $5M+ | Median of those sales | Price per m² (per sq ft) |
|---|---|---|---|
| Porsche Design Tower | 2 of 12 | $9.1M | about $13,100 ($1,214) |
| Turnberry Ocean Club | 15 of 15 | $5.6M | about $20,600 ($1,913) |
| Residences by Armani/Casa | 2 of 19 | $5.4M | about $18,300 ($1,699) |
| Jade Signature | 6 of 19 | $9.8M | about $18,300 ($1,703) |
How to read them. These 12 sales are a floor, not a full count. The roll keeps only the two most recent sales of each residence, and a deed that closes a long pre-construction contract can fall outside the arm's-length code. Asking prices on listing portals, Zillow among them, are sellers' figures, not recorded prices. This site shows no unit numbers and no owners.
Values for tax. The county appraiser's estimate of market value, the just value, runs from $2.66 million to $19.1 million here, and across the 132 residences it adds up to $508.9 million. Just value is an appraisal, not a price. Nine residences (6.8%) carry a homestead exemption, a floor for the share of homes their owners live in.

Property tax. The combined property-tax rate in Sunny Isles Beach for 2025 was 16.7227 mills: $16.72 for every $1,000 of taxable value, or about 1.67% a year. A residence assessed at $5 million that is not the owner's Florida homestead would pay about $83,600 a year. After a purchase, the assessment resets to full market value on the next 1 January. The appraiser's just value can differ from the price paid; for this building the median just value on the 2026 roll is $3.16 million.
Assessment caps. For a residence that is not the owner's Florida homestead, the assessed value used for non-school taxes may rise by no more than 10% a year. Amendment 3, which Florida voters approved on 3 November 2026, lowers that cap to 5% from the 2027 roll; the state had not yet certified the result on 9 November 2026. The homestead exemption itself is open only to an owner who makes the home a permanent Florida residence in good faith, a test a person in the United States on a temporary visa cannot meet.
HOA fees. The association's budget was not found in a public source, so its fees are not known here. Before an offer, ask the seller for the last two budgets, the reserve schedule and the building's insurance policies. The car-elevator system is a maintenance cost worth asking about.
At purchase. Florida's documentary stamp tax on the deed is $0.60 for every $100 of the price in Miami-Dade County, about $24,600 at this building's median of $4.1 million; the purchase contract decides which party pays it. Miami-Dade's additional surtax of $0.45 per $100 does not apply, because state law counts a condominium unit as a single-family residence, which is exempt. A mortgage adds documentary stamp tax of $0.35 per $100 of the loan and an intangible tax, a state tax on the loan itself, of $2 per $1,000.
§ 08Porsche Design Tower
After the 2021 collapse in Surfside, Florida requires two checks of every condominium building three or more habitable stories high.
Status here. The state's Department of Business and Professional Regulation (DBPR) keeps two SIRS databases. In their full exports of 9 November 2026, neither shows an entry for 18555 Collins Avenue Condo, its association, 18555 Collins Avenue Condo Assn Inc, or the address. A missing filing is not proof that no study was done. By law the study was due by 31 December 2025, or by 31 December 2026 if combined with a milestone inspection, so one should exist: ask the seller for it. No building-by-building milestone list was found on the City of Sunny Isles Beach Building Safety page.
What a resale buyer is entitled to. On a resale the seller must give the buyer, at the seller's cost, the declaration of condominium, the articles, bylaws and rules, the annual financial statement and budget, and the association's question-and-answer sheet and governance form. The package also carries the most recent structural integrity reserve study, or a statement that none was done, and the summary of the milestone inspection report where one applies. If the developer handed control to the owners after 1 July 2023, the turnover inspection report is included too.
The buyer may cancel within 7 days of receiving the documents, weekends and legal holidays not counted. That right falls away if the contract records receipt more than 7 days before signing, and it ends at closing. A buyer who purchases from the developer has 15 days instead.

The revised flood maps bring this building into FEMA's high-risk flood area. From 19 February 2027 its map point lies in Zone AO, an area of shallow flooding where the figure given is the expected depth of water: 3 feet here. On the current maps, in force since 11 September 2009, the same point lies in Zone X (unshaded), where flood risk is minimal.
Toward the beach the current maps show Zone AE, the area with a 1% chance of flooding in any year, at a base flood elevation of 9 feet (2.7 m). Nearer the water lies Zone VE, at 10 feet (3.0 m), where storm waves strike and building rules are strictest. A base flood elevation is the height water is expected to reach in a 1%-a-year flood, measured from the map's reference level (NGVD29 on the current maps), never a depth of water above the ground. In Zone AE a mortgage lender usually requires flood insurance.
On the revised maps the VE zone keeps a base flood elevation of 10 feet, now measured from a newer reference level (NAVD88). It begins about 40 meters east of the building's map point, against about 110 meters today: some 70 meters closer. These are readings of FEMA's National Flood Hazard Layer, not official flood-zone determinations.
Like all of Sunny Isles Beach and Golden Beach, the address sits in Miami-Dade Storm Surge Planning Zone B, where storm surge, the sea water a hurricane pushes ashore, is a risk from Category 2 storms upward. The county orders evacuations by each storm's track and projected surge, not by category alone.
Flood insurance. The National Flood Insurance Program (NFIP) covers up to $250,000 for a residential building and $100,000 for contents. A condominium association's building policy can reach $250,000 multiplied by the number of units, or $33 million for the 132 units in the recorded condominium. At these values, cover above the NFIP limits is bought privately.
Windstorm insurance. Citizens, Florida's state-backed insurer of last resort, may not write a unit owner's policy where the unit's combined dwelling and contents replacement cost is $700,000 or more. The threshold rises to $1 million in counties where the state insurance regulator finds too little competition. What counts is the cost of rebuilding and refitting the unit, not the price paid; the association's policy for the building is a separate matter. An insurance agent can say whether a given unit qualifies.

Three rules weigh most for a buyer from abroad, and each carries conditions. When the seller is a foreign person, the buyer generally must withhold 15% of the price and pay it to the IRS, under the federal rule known as FIRPTA. A nonresident who is not a US citizen and holds US real estate directly is exposed to US estate tax. The third rule is Florida's own.
Florida's foreign-ownership law of 2023 covers people domiciled in China, Russia, Iran, North Korea, Cuba, Syria or under the Venezuelan regime of Nicolás Maduro who are not US citizens or green-card holders. It limits their purchases near military and critical-infrastructure sites and, for those domiciled in China, anywhere in Florida, with one narrow exception for a single home.
On this coast that exception is the only way in. The law counts a facility only where it is fenced, barred or guarded, and two that meet the test lie within 10 miles of every address. Fort Lauderdale-Hollywood International Airport is secured under the federal airport security program and Port Everglades under federal port security rules; both are about 6 to 10 miles away.
Two more facilities of the kinds the law lists are nearby: the Miami-Dade North District wastewater treatment plant, about 1 to 4 miles away, and North Perry airport, about 6 to 10. The nearest military installation, at Dania Beach, is about 8 to 12 miles away, beyond the 5 miles the exception requires.
A covered person may therefore buy here only one residential property of up to 2 acres, in their own name, with a current US visa not limited to tourism or with official asylum documentation. The purchase must be registered with the Florida Department of Commerce within 30 days. Companies and other entities covered by the law may not buy here. Each rule is set out in full in the guide to buying from abroad; this is general information, not legal or tax advice.
Rentals of six months or less need, among other requirements, a city short-term rental license for each unit and either the association's written consent or a copy of its bylaws; the condominium's documents may restrict rentals further. The same documents decide whether the association must approve a buyer, whether a company may hold title and what minimum lease term applies. They were not found in public sources.

On the state's 2026 roll, 12 arm's-length sales between January 2025 and June 2026 ran from $3.2 million to $13.0 million, with a median of $4.1 million. The 2 sales at $5 million or more had a median of $9.075 million. Asking prices of units and penthouses for sale are a separate matter.
About $13,100 per m² ($1,214 per sq ft), the median of 12 arm's-length sales.
18555 Collins Ave, Sunny Isles Beach, FL 33160, recorded as 18555 Collins Avenue Condo. It is in Miami-Dade County, in the City of Sunny Isles Beach rather than Miami or Miami Beach.
641 ft (195.4 m) to its architectural top, by CTBUH's count, with 132 residences.
The developer calls it the Dezervator. A turntable aligns the car, a shuttle moves it into the cabin, and the cabin turns to the owner's garage beside the residence; RFID tags direct each car. Mid-American Elevator supplied the system.
Dezer Development built the tower with Porsche Design. CTBUH names The Sieger Suarez Architectural Partnership as architect; the builder also credits Porsche Design Studio, and CTBUH credits the interiors to Studio F. A. Porsche.
Its residences belong to their individual owners, and the common areas to all of them through the condominium association. Dezer Development built it with Porsche Design.
This page answers structural questions only from public records. The building dates from 2016, so its first milestone inspection is due by the end of 2046, or of 2041 under the 25-year option. No structural integrity reserve study was found in either state database on 9 November 2026, which is not proof that none exists. The seller can be asked for the latest study and the association's engineering reports.
Yes: the builder gives about 15,000 sq ft (1,394 m²) for the penthouses. The highest arm's-length sale in the period was $13 million.
The developer states that most residences have a private pool on the balcony and lists a spa and a sunset terrace with spa tubs. The sources consulted describe no shared pool.
No budget was found in a public source. A resale buyer is entitled to the budget and the annual financial statement, which show the fees, the reserves and any special assessments.
Pet rules sit in the declaration, which no public source reproduces; ask for it before an offer. Assistance animals must be allowed in every case.
This page is not a review and quotes no testimonials. What an adviser can check is the public record cited below: the condominium registry, the recorded sales, the SIRS databases and the FEMA map.
The answer lies in the condominium's documents rather than in city law. The city's short-term rental ordinance does not limit how often a unit is rented, while the documents may restrict frequency and set a minimum term; they were not found in a public source.

Viewings at Porsche Design Tower are arranged through a licensed real estate broker. For a buyer abroad, a video walk-through of the residence can take the place of the first visit.
Before the visit, ask for the association's last two budgets, the SIRS and the declaration's rules on leasing, pets and buyer approval. Pet rules always allow assistance animals as the law requires.
