Una Residences Penthouse Sells for $17.8M: Brickell Bay Hits $2,900 Per Square Foot in May 2026

The Una Residences penthouse closing matters because it is the first nine-figure-per-foot data point at Una since the 47-story tower received its Temporary Certificate of Occupancy in February 2026. The Real Deal's May 13 column confirmed the $17.8 million transaction at 175 SE 25th Road, designed by Adrian Smith and Gordon Gill, the architects behind the Burj Khalifa. For Brickell Bay buyers, this is the comparable that closes the gap between Brickell financial-core pricing and the South-of-Fifth and Surfside ceilings. For pre-construction buyers in Brickell, Edgewater, and Coconut Grove, it confirms that finished, branded, water-direct product can clear at premium pricing without discounting.

The Una Residences Closing: What The Real Deal Reported on May 13

The Real Deal published South Florida's top closings for the week of May 12 on May 13, 2026, and Una Residences led the condo list. The unit was a penthouse at 175 SE 25th Road, the address that puts Una directly on Brickell Bay at the southern edge of the Brickell financial corridor. The buyer of record was NZC Miami LLC. The unit measured roughly 6,100 square feet, and the recorded price was $17.8 million, which works out to approximately $2,900 per square foot. OKO Group and Cain were named as the developers and sellers on the transaction.

According to Florida YIMBY (February 2026), Una received its Temporary Certificate of Occupancy in February 2026, which is the regulatory moment when a building can legally close and deliver units to buyers. That makes this May 2026 penthouse closing one of the first post-TCO trophy-tier transactions at the project. According to Miami Realtors Q1 2026 condo data, the Brickell submarket average sat at roughly $1,250 per square foot for new product. The Una penthouse cleared at more than twice that, which sets a new upper bound for Brickell Bay branded delivery.

Why Una Commands a Premium: Adrian Smith and Gordon Gill, Yacht-Form Architecture, and Bayfront Frontage

Una was designed by Adrian Smith and Gordon Gill Architecture. The firm is best known for the Burj Khalifa in Dubai and Jeddah Tower in Saudi Arabia, the tallest and second-tallest buildings ever constructed. According to the developer marketing materials, the curves of Una's facade are intentional, referencing classic Italian yacht hulls. The name itself comes from the Riva Aquarama and similar Italian sailing-yacht traditions, and the planning approvals process placed the tower directly on the Brickell Bay frontage south of the Rickenbacker Causeway sightline.

Three building-level factors drive Una pricing above the Brickell average:

• Direct bay frontage with unobstructed views: Una sits east of the South Bayshore Drive setback, which means lower-level views are unblocked and upper floors look directly over Biscayne Bay toward Key Biscayne. According to the Florida YIMBY 2026 profile, the site footprint at 175 SE 25th Road was specifically chosen for this view corridor.
• Penthouse-level amenities priced into the unit: Penthouse residences at Una include dual private pools, a summer kitchen, sauna, and steam room within the unit, per the developer marketing materials. Those private wellness features compress comparable shopping with hotel-branded buildings like the St. Regis Brickell Residences where similar features sit in shared amenity decks.
• Architect signal value: A building designed by the Burj Khalifa firm carries international resale recognition. According to The Real Deal Miami's running tracker, Adrian Smith and Gordon Gill projects in the Americas trade at a measurable premium versus comparably-located non-branded designs.

Una is a 47-story tower with finished delivery, which puts it in a different sales cycle than ongoing Brickell pre-construction. Buyers can walk the building, see the actual views from the unit, and close immediately. According to the Keyes and Illustrated Luxury Report Q1 2026, finished-delivery branded product in Brickell traded at a 12 to 18 percent premium versus comparable pre-construction units in the same submarket.

How $2,900 Per Foot at Una Compares to Other Miami Branded Towers This Spring

The Una penthouse closing does not exist in isolation. Three other May 2026 luxury condo closings in the same broad market window give it real comparable context. On May 14, Surf Club Seaway North in Surfside closed a 7,900-square-foot penthouse for $41 million, or roughly $5,190 per square foot, per The Real Deal. On April 27, Fort Partners closed three Surf Club units totaling $121 million and four units totaling $161 million at the same complex. Across town in Brickell, St. Regis Residences Miami and Waldorf Astoria Residences Miami have both reported pre-construction contracts in the $1,800 to $2,400 range for non-penthouse floors.

The takeaway is structural. Surfside oceanfront branded product sits at the top of the South Florida condo stack, in the $5,000 per square foot range. Brickell Bay branded delivery now has a defensible $2,900 anchor at Una. Brickell financial-core pre-construction sits in the $1,800 to $2,400 range, which means pre-construction buyers in that tier still have room before pricing converges with finished-product comparables. According to Knight Frank's Wealth Report 2026, Miami appeared in the top three global cities for branded-residence demand growth, and the spread between pre-construction and finished branded product typically compresses by 18 to 25 percent over a delivery cycle.

For Brickell pre-construction buyers, the practical implication is clear. The pre-construction buying process step by step guide walks through the deposit schedule, but the Una comparable is the data point that matters at the underwriting stage. A buyer signing a $1,800 per square foot Brickell pre-construction contract today, with delivery in 2027 or 2028, has a credible $2,900 ceiling once the building is finished if execution holds. The condo building financial health guide remains the right framework for evaluating which projects clear that bar.

My Recommendation: How to Use the Una Comparable When Negotiating Brickell Pre-Construction

I have walked clients through Una during sales gallery tours over the last 18 months, and the May 2026 penthouse closing changes how I price the rest of the Brickell stack for clients. Here is what I tell buyers depending on where they sit.

If you are evaluating a new Brickell pre-construction launch in the $1,500 to $2,000 per square foot range, Una is now the comparable the developer will cite to justify pricing. That works in both directions. It supports the developer's pricing, and it gives you a real ceiling for resale modeling. Bring the Una closing to the negotiation explicitly. I have done this with three clients since May 12, and it shifted the conversation away from "developer asks" toward "comparable evidence."

If you are evaluating Brickell resale in finished branded buildings, Una recalibrates the upper bound. Older branded Brickell product at $1,500 to $1,800 per square foot looks more attractive once a brand-new Adrian Smith and Gordon Gill building closes at $2,900. The Real Deal's May 13 report does not say Brickell is overpriced. It says Brickell now has a verified premium ceiling. Foreign national buyers should also review the foreign national buyer guide for FIRPTA, financing, and entity structuring before approaching any of these closings.

If you are a Brickell Bay buyer specifically targeting bayfront or direct-water frontage, Una is the only finished comparable that sits in this exact corridor. Adjacent pre-construction options in Coconut Grove or Edgewater have water frontage but a different submarket dynamic. Use the true cost of owning a Miami luxury condo guide to model HOA fees, taxes, and reserve assessments at Una versus a 2028-delivery pre-construction alternative before deciding.

"A $2,900 per square foot closing at a brand-new Adrian Smith and Gordon Gill tower is not a one-off. It is the first verified post-TCO data point we have for Brickell Bay branded product, and it gives every pre-construction conversation in Brickell a defensible upper anchor for the next 18 months. Buyers who treat this as the comparable will negotiate from evidence, not narrative." Gerardo Gonzalez, Licensed Agent at Compass

Frequently Asked Questions

Where is Una Residences located in Miami?

Una Residences sits at 175 SE 25th Road in Miami's Brickell Bay submarket, just south of the Brickell financial core and directly on Biscayne Bay. The 47-story tower was designed by Adrian Smith and Gordon Gill, the architects behind the Burj Khalifa and Jeddah Tower. OKO Group and Cain received TCO in February 2026.

What is the price per square foot at Una Residences?

The May 2026 penthouse closing translated to roughly $2,900 per square foot. That sits above the Brickell condo average of approximately $1,250 per square foot reported by Miami Realtors for Q1 2026, but below recent Surfside oceanfront penthouse closings such as Surf Club Seaway at $5,190 per square foot.

Who designed Una Residences in Miami?

Una Residences was designed by Adrian Smith and Gordon Gill Architecture, the firm responsible for the Burj Khalifa in Dubai and the Jeddah Tower in Saudi Arabia. The building's yacht-inspired curves are intentional, referencing the Italian sailing tradition that gave the project its name.

Should I buy pre-construction in Brickell after the Una sale?

A single $2,900-per-square-foot closing does not move the entire Brickell market, but it confirms that the top of the Brickell Bay stack is finding buyers without discounting. Pre-construction units in adjacent Brickell projects priced in the $1,200 to $1,800 per square foot range now have a credible upper-end comparable, which supports resale value as those buildings deliver in 2027 and 2028.
