Top Luxury Brickell Condos: Brickell Flatiron, Una Residences & SLS LUX

If you're cross-shopping the top delivered luxury condos in Brickell, three buildings consistently lead the conversation: Brickell Flatiron (CMC Group, 2019), Una Residences (OKO Group, 2024), and SLS LUX Brickell (Related Group, 2018). All three are delivered, walk-it-tomorrow product. All three were built with serious design pedigree. And all three trade meaningfully above the Brickell building-average for their respective vintages.

Each makes a different case for the premium. This guide pulls the three buildings side by side — architect, developer, amenity program, pricing, lines that hold value — and tries to answer the question buyers actually ask: which of the three is right for me?

The Quick Comparison

1. Brickell Flatiron — Design-Led, Sky-Amenity Trophy

Brickell Flatiron is Ugo Colombo's CMC Group flagship — a 64-story, 736-foot tower at 1001 S Miami Avenue, designed by Revuelta Architecture International with interiors by Massimo Iosa Ghini. When it received its TCO in October 2019, it briefly held the title of tallest residential condominium in Miami.

The case for Flatiron:

• Curvilinear architecture — Revuelta's flowing south façade is one of the most recognizable forms on the Brickell skyline, a deliberate departure from the rectilinear glass that dominates the neighborhood
• Named-designer residences — Iosa Ghini (Italian designer known globally for the Ferrari showroom rollout) executed both common areas and residences as one coherent program
• 64th-floor Sky amenities — Sky Pool, Sky Spa, and Sky Gym at the very top of the building. Very few Miami condos give residents daily-use access to a pool and full fitness facility on the top floor
• Long resale track record at this point — six years of comp data, including multiple penthouse transactions
• 23 distinct floor plans (14 tower + 9 penthouse), meaningful diversity vs typical stacked-identical inventory

The case against:

• Largest unit count of the three (~523 residences) — denser building than Una
• No bay-direct frontage — Brickell central core, not bayfront. East-facing upper-floor lines capture Biscayne Bay views but the building doesn't sit on the water
• HOA range is wide (~$1,100 to $10,841/mo depending on residence size)

Pricing band: 1BR ~$800K-$1.2M · 2BR mid-$1Ms to ~$2M · 3BR $2M-$3.5M · 4BR $3.55M+ · Trophy penthouses $18M-$20M+

2. Una Residences — Yacht-Inspired Bayfront

Una Residences is the newest of the three — delivered in 2024 by OKO Group (Vladislav Doronin) and Cain International, the same team behind Missoni Baia in Edgewater. It sits at 175 SE 25th Road on Brickell's south waterfront, a 47-story tower with roughly 135 residences and direct Biscayne Bay frontage.

The architectural form is the headline — designed by Adrian Smith + Gordon Gill Architecture (the firm behind several global supertalls), Una's silhouette curves and tapers in a way that reads as yacht-inspired from every angle. The result is one of the most distinctive deliveries on the Brickell waterfront in the post-2020 cycle.

The case for Una:

• Direct bayfront frontage — most of the highest-end Brickell trophy product sits inland or in the central core; Una puts buyers directly on the bay
• Lowest unit density of the three (~135 residences) — meaningfully more boutique than Flatiron or SLS LUX
• Newest delivery — fresh finishes, latest reserve cycle, no immediate post-Surfside inspection concern
• Private marina with bay access — a real, used amenity, not just marketing
• OKO Group execution — Doronin's firm has delivered Missoni Baia, Una, and Aman (in New York) at consistent finish quality
• Larger residence sizes on average than Flatiron or SLS LUX — Una's floor plans skew toward 2BR+ with limited 1BR product, which means the resident base is more owner-occupier and less rental-investor

The case against:

• Highest entry price of the three — Una starts higher because the 1BR pool is small
• Newest building, shortest comp history — only ~2 years of resale data at this point
• Inland walkability is weaker than Flatiron/SLS LUX — Una sits south of the Brickell core, so walking to restaurants and Brickell City Centre is meaningfully longer
• Smaller resident community can cut both ways — privacy advantage, but fewer amenity-deck residents means the resort deck reads as quieter

Pricing band: 2BR ~$1.4M-$2.8M · 3BR ~$2.5M-$5M · 4BR ~$5M-$10M+ · Penthouses $15M-$25M+ depending on stack

3. SLS LUX Brickell — Hotel-Branded, Art-Driven

SLS LUX Brickell is the hotel-branded condominium in the trio — delivered in 2018 by Related Group and Allen Morris Company, designed by Arquitectonica with interiors by Yabu Pushelberg. At 57 stories and roughly 450 residences at 801 S Miami Avenue, it sits directly across from Brickell City Centre.

What sets SLS LUX apart is the art program and hotel-service infrastructure. The building features a curated contemporary art collection across public spaces — including a large-scale Markus Linnenbrink installation — and operates with SLS-branded hotel services integrated into the resident experience. For buyers who value brand-managed service over residential-only privacy, SLS LUX is the most service-driven of the three.

The case for SLS LUX:

• Hotel-branded service — concierge, valet, F&B, and turn-down service operate at hotel standard rather than typical condo standard
• Yabu Pushelberg interiors — globally recognized hospitality interior firm; the lobby and common areas read like a luxury hotel, not a residential lobby
• Most rental-friendly bylaws of the three — SLS LUX historically allows more flexible short-term rental programs (verify current rules before underwriting)
• Brickell City Centre adjacency — directly across from Miami's primary luxury retail anchor (Saks Fifth Avenue, restaurants, cinema)
• Lower entry price — 1-bedroom inventory typically starts the lowest of the three buildings
• Curated art program — daily-life immersion in a contemporary art environment is rare in condo product

The case against:

• Hotel-component density — the building shares amenities with hotel guests on certain levels; some residents prefer pure residential
• Brand-licensing risk — branded residences with hotel operator contracts have long-tail questions about brand longevity and operator changes
• Smaller residence sizes on average than Una; SLS LUX has a wider mix including studios and small 1BRs
• Less distinctive architecturally than Flatiron or Una — Arquitectonica's tower reads more as standard high-rise than as a signature form

Pricing band: Studio / 1BR ~$700K-$1.1M · 2BR ~$1.2M-$2.2M · 3BR ~$2.2M-$4M · Penthouses $5M-$8M+

Side-by-Side: Which Building For Which Buyer

Honorable Mentions in Brickell

The three buildings above lead the delivered-luxury conversation, but they aren't the only Brickell trophy product worth comping:

• Echo Brickell — 180-unit boutique tower with private plunge pools on every residence; smaller, more private, premium pricing
• Brickell City Centre Reach + Rise — directly connected to Brickell City Centre mall via skybridge; SLS LUX is across the street, Reach + Rise is on top
• 1 Hotel & Homes (Brickell, where applicable) — hotel-branded residential with eco-luxury positioning
• 888 Brickell Dolce & Gabbana — pre-construction supertall, fashion-branded, fully furnished (not delivered yet)
• Baccarat Residences Brickell — pre-construction Baccarat-branded, riverfront variant (not delivered yet)
• Cipriani Residences Brickell — pre-construction members'-club service stack (not delivered yet)
• Mandarin Oriental Brickell Key — pre-construction Mandarin-branded on Brickell Key (not delivered yet)

For buyers willing to wait for pre-construction, the pre-con cluster will reset Brickell's top-end pricing meaningfully over the next 2-4 years. For buyers who want a walk-it-tomorrow trophy address, Flatiron, Una, and SLS LUX are the three to compare.

How To Choose Between the Three

A simple decision tree:

1. Do you want to be on the water? If yes → Una Residences is the only one of the three on direct bayfront. Stop here.
2. Do you want hotel-managed service and the highest rental flexibility? If yes → SLS LUX Brickell is the only hotel-branded of the three. Stop here.
3. If neither bayfront nor hotel service is a hard requirement → Brickell Flatiron wins on design pedigree, amenity scale (especially the 64th-floor Sky deck), and resale comp depth.

For most full-time-resident, design-conscious buyers who don't need water frontage or hotel service, Brickell Flatiron is the default answer in this trio.

For buyers who specifically want the newest, smallest-density, on-the-water product in Brickell, Una Residences is the answer.

For buyers who want hotel-branded service + the lowest entry price in trophy Brickell product, SLS LUX Brickell is the answer.

The Risk Side

All three buildings carry standard delivered-luxury Brickell risk:

• HOA trajectory — Brickell luxury HOAs have climbed meaningfully since 2022 driven by insurance and the post-Surfside reserve regime
• Structural-integrity milestone inspections — required across Florida; relatively low concern on buildings delivered 2018+ but verify the latest report
• Resale liquidity by line — water-facing or distinctive-line product clears reasonably; non-distinctive lines run longer days-on-market in any of the three
• STR restrictions — vary by building; SLS LUX has historically been the most flexible. Verify exact bylaws before underwriting rental income
• Branded-residence brand longevity — Iosa Ghini, OKO, and SLS each carry different brand-risk profiles; SLS hotel-operator contract changes are the most acute case to watch

Bottom Line

Brickell's top three delivered luxury condos each make a distinct case:

• Brickell Flatiron — design-led trophy with the 64th-floor Sky deck, deepest amenity stack, and broadest floor-plan diversity
• Una Residences — newest, smallest, on-the-bay, OKO-Group-executed boutique product
• SLS LUX Brickell — hotel-branded service at the most accessible entry price, with the most flexible rental bylaws

Comp across all three before fixating on one. The right answer depends on whether you want water frontage, hotel service, or pure design-led residential — and on your specific line and floor preferences within each building.
