Glass Miami Beach

What is actually in the building

The county returns 12 folios at 120 Ocean Drive. Ten are homes. One is a reference folio carrying no dwelling, and one is a 708 sq ft ground-floor store classified commercial, which the county assesses at $1,699,200. Neither is included in any figure on this page.

The building is unusually simple. Seven of the ten homes are the same 3,389 sq ft floorplan — one to a floor. Two more are 1,938 sq ft, and the tenth is a 7,538 sq ft penthouse. Seven of the homes are three-bedrooms and two are two-bedrooms; the county leaves the bedroom field blank for the penthouse, so I am not stating a figure for it.

That structure matters more than it might sound. When seven of ten homes are identical, the building offers something most do not: a clean like-for-like comparison across time, with no floorplan mix to muddy it. Most of what follows depends on that.

For 2026 the county assesses the homes between $3,475,393 and $16,040,275, median $5,877,060. Among the seven identical 3,389 sq ft homes the assessments still rise steadily with height, from $5,200,937 to $6,970,229 — a 34.0% spread on homes of exactly the same size.

Did the buyers who paid the most do the worst?

At this building, yes — and the record is unusually clean about it.

Glass sold through in October and November 2015: ten of its eighteen recorded sales fall in those two months. Within the seven identical 3,389 sq ft homes, the developer priced by floor, and buyers paid between $1,888 and $2,626 per square foot for the same floorplan — a 39.1% spread driven by height alone.

Five of those seven have since resold. Here is every one of them, ordered by what the 2015 buyer paid per square foot:

The order is exact. Rank those five homes by what the original buyer paid per square foot and you get precisely the same order as ranking them by outcome, from best to worst, with no exceptions. The cheapest entry was the only clear gain; the most expensive was the worst loss.

I want to be careful about what this does and does not establish, because five data points is five data points.

What it does not mean is that the higher floors are bad homes, or that height is not worth paying for. The county still assesses the top of this building 34.0% above the bottom on identical square footage, and the resale prices themselves still rise with height — unit 1500 resold at $2,213 per square foot while unit 900 resold at $2,125. Height retains a premium; it simply retained a smaller one than the 2015 buyers paid for.

What it does mean is that the developer’s floor premium was priced ahead of what the resale market has since been willing to pay for it. The homes that were cheapest relative to the building have closed the gap; the ones that carried the largest premium have given part of it back. Because every one of these homes is 3,389 sq ft, none of that can be explained by size, mix, or which floorplans happened to trade.

The three other resales on the record, all of unit 600, tell the same story more bluntly. Unit 600 sold for $4,500,000 in December 2016 and for $4,500,000 in May 2024 — the identical price, seven and a half years apart, on the same 1,938 sq ft home. Before that it had gone $3,400,000 in October 2015 and $4,575,000 in February 2016, a 34.6% gain in four months, and since December 2016 it has neither gained nor lost.

The price record

No four-year change is published and the building carries a dash in my Miami Condo Index. Three of the four years are empty and the fourth holds two sales. That is not a trend and I will not present it as one.

What those two 2024 sales do establish is a level: $7,200,000 for a 3,389 sq ft home in January at $2,125 per square foot, and $4,500,000 for a 1,938 sq ft home in May at $2,322. Both are the most recent evidence this building has. The $2,125 sits inside the $1,992 to $2,213 per square foot range of the 3,389 sq ft resales since 2019; the $2,322 is for the smaller 1,938 sq ft floorplan.

The record price is $20,000,000, paid on 20 October 2015 for the 7,538 sq ft penthouse — $2,653 per square foot. It has never resold. The county now assesses it at $16,040,275, though that figure is a tax assessment rather than a valuation and should not be read as a market view.

The ownership record is the weakest part of this building’s case. Of the eight resales on the county record, four lost money — 50.0% — at a median outcome of −0.8% over a five-year hold. A median of essentially zero is unusual. Most buildings I measure sit clearly in positive territory — Capri South Beach at +17.9%, The Neville at +40.9%, 321 Ocean at +41.8% — and several have never recorded a single loss. Glass has recorded four in eight.

Turnover is one home in 20 a year (two sales in the last four years across ten homes), against one home in 23 for the median building in my Miami Condo Index. The building trades; it simply has not traded at rising prices.

Who this building suits, and who it does not

It suits a buyer who wants a full-floor home in a ten-home building on Ocean Drive and is buying it to live in. The product is genuinely scarce — one 3,389 sq ft home per floor, in a building where the entire ownership is nine other households.

It suits a buyer negotiating from evidence. This is a rare building where you can point to five like-for-like resales of an identical floorplan, three of them below the original price and two above it, and where the pattern of who lost is not a matter of opinion. That is a strong position to negotiate from and very few buildings hand it to you.

It suits badly anyone expecting the 2015 pricing to be reasserted. It has not been in eleven years, and the homes that carried the largest floor premium are the ones that have given the most back.

It suits badly a buyer who needs current comparables. There have been no qualified sales here since May 2024.

If you are selling here, be realistic about which half of the building you are in. If you bought low in 2015 or later, the record supports a modest gain and the January 2024 sale at $2,125 per square foot is your anchor. If you are one of the higher-floor original buyers, the evidence in your own building says the floor premium you paid has not held, and a well-prepared buyer will find that in ten minutes on the county record. The stronger argument in that case is not the 2015 price but scarcity: full-floor homes on Ocean Drive, ten households in the building, and a market where nothing comparable has come up since 2024.

It’s called Glass for a reason. This 18-story condo building is like an oceanside chandelier, perched above the exclusive South of Fifth Street neighborhood of Miami Beach, designed explicitly so that as it rises, it seems to dissipate into the atmosphere. Josh Stein loves to market these units not only because they are perfectly situated, spacious, and modern — they’re also largely customizable. “Each owner was encouraged to work with Rene Gonzalez, the architect, to develop the interior lighting and design,” Josh says.

Completed in 2015, Glass was part of a new boom in sleek, modern luxury in one of Miami’s most desirable neighborhoods. But Glass is particularly special because of its exclusivity: It has 18 floors and only 10 units.

And each residence is designed to be uniquely glamorous. The 18th floor is a master suite. The 17th floor has a floating glass interior staircase, all-marble kitchen, and 40-foot-long infinity pool. The 16th floor has a media room and gym. Every square foot is designed to be an experience, from the interactive wall in the lobby to the elevator installation that mimics the sea and sky as it climbs. “Elsewhere, the building’s mirrored walls at each entry were put there to reflect the spectacular view of the Atlantic Ocean,” the building’s designers said. In the residences, each owner can see it for his or herself through sprawling floor-to-ceiling windows.
