Una Residences: Bjarke Ingels Brings Sculptural Modernism to Brickell Key
BIG — Bjarke Ingels Group — designed Una Residences as a twisting, tapering tower that rises from the southern tip of Brickell Key like a sail catching the Biscayne Bay breeze. The result is one of the most architecturally ambitious residential buildings in Miami's history.

A Tower That Belongs to the Water
Brickell Key remains one of Miami's most exclusive addresses — a compact island in Biscayne Bay tied to the mainland by a single bridge, offering enclave-level privacy with Brickell's financial district minutes away. For decades the island's residential stock delivered competence without character. Then came Una Residences.
Completed in 2023 at 175 SE 25th Road, Una was conceived by BIG — Bjarke Ingels Group — the Copenhagen practice that has defined much of contemporary architecture. BIG arrived with a globally visible portfolio that includes the LEGO House in Billund, the Amager Bakke waste-to-energy plant in Copenhagen (with a ski slope on the roof), and Google's Mountain View campus. At Una, the firm paired formal ambition with pragmatic intelligence and reset expectations for luxury residential design on the island and across Miami.
Bjarke Ingels and the BIG Philosophy
Bjarke Ingels launched BIG in 2005 after a formative period with Rem Koolhaas at OMA. The practice promotes "pragmatic utopianism" — ideas that are visionary and buildable at once, where daring form and programmatic function amplify each other.
Una distills that philosophy into one decisive gesture: a tower that tapers and twists as it rises. Floor plates rotate slightly at each level to maximise views and generate a sense of motion. The silhouette reads as sculpture from Biscayne Bay, the Brickell skyline, and from the air. The move also produces measurable benefits: every residence secures unobstructed water views, and the building's orientation captures prevailing breezes while reducing solar gain.
A continuous curtain wall of floor-to-ceiling glass defines the facade, interrupted only by deep balconies that extend from every residence. These balconies — some exceeding 15 feet in depth — act as true outdoor rooms suited to year-round use in Miami's subtropical climate, not as cosmetic add-ons.
The Architecture: Twist, Taper, and Light
Una's structural logic mirrors its formal clarity. A concrete core provides lateral stability while perimeter columns, expressed as vertical fins on the facade, carry floor loads. The twist arises from a sequence of slightly rotated floor plates, each offset from the one below to create the tower's spiral profile.
At ground level the building steps down to the water through landscaped terraces that lead to the private marina. The bay is a design driver: Una embraces the water instead of turning its back on it. Pool, beach club, and marina interlock to produce a continuous waterfront experience.
The crown, where the tower narrows, contains the penthouse residences. The uppermost floors deliver 360-degree views across Biscayne Bay, the Atlantic Ocean, the Miami skyline, and the Everglades to the west — a panorama rare in South Florida.
Interiors: Warm Modernism by Arquitectonica Interiors
Arquitectonica Interiors translated the exterior's sculptural intent into warm, disciplined living spaces. The brief avoided competing with the form: materials and detailing recede so views and architecture remain the focus.
Finishes read as understated luxury: large-format natural stone floors, custom light-oak millwork, and a neutral palette that shifts with bay light. Kitchens specify Italkraft cabinetry, Sub-Zero and Wolf appliances, and waterfall-edge stone counters. Bathrooms use book-matched marble, freestanding soaking tubs, and frameless glass enclosures.
Ceilings are generous — 10 feet in standard residences and 12 feet in penthouses — while floor-to-ceiling glazing floods interiors with daylight. Deep balconies form a layered threshold between inside and out, one of Una's most distinctive spatial qualities.
The Residences: Scale and Exclusivity
Una contains 135 residences across 47 floors — a deliberate density that privileges scale and privacy. Units begin at 2,300 square feet for three-bedroom plans and extend beyond 8,000 square feet in the penthouse collection. There are no small apartments; every home delivers expansive living areas, multiple en-suite bedrooms, and private outdoor space.
The penthouse collection occupies the building's upper floors with full-floor residences and private rooftop terraces. These homes represent the project's pinnacle: double-height living rooms, private plunge pools on terraces, and horizon-to-horizon views. Penthouses price between $15M and $35M.
Standard residences start at approximately $3M for a three-bedroom unit, with four-bedroom residences beginning at $5M. With only 135 units in a market where comparable towers often contain 300+ units, Una's scarcity underpins both its pricing and its appreciation trajectory.
Amenities: The Private Island Experience
Una's amenity program exploits its waterfront position. A private marina accommodating vessels up to 100 feet lets residents dock a yacht steps from their front door — a genuinely rare convenience even in a water-centric city.
The pool deck sits at the water's edge and features an infinity pool that visually dissolves into Biscayne Bay. The waterfront program also includes a beach club, spa, and fitness centre. The spa offers treatment rooms, a steam room, a sauna, and a vitality pool; the Technogym-equipped fitness centre includes a dedicated yoga and Pilates studio.
Concierge services manage yacht charters, private chefs, helicopter transfers, and curated Miami and Caribbean experiences. Brickell Key's single-bridge connection creates a natural security perimeter, intensifying privacy and exclusivity.
The Investment Case
Brickell Key has long produced stability, with steady demand from international buyers, corporate executives, and seasonal residents. Una elevated the island's profile: its architectural pedigree and the scarcity of 135 units command a clear premium and have driven robust appreciation since delivery.
At launch in 2019, residences started at approximately $2M. By 2026 comparable units trade in the $3.5M to $6M range, representing appreciation of 75% to 200% over the pre-construction period. The rental market supports those values: best-in-class residences lease for $15,000 to $40,000 per month.
For investors, Una bundles scarcity, location, and architectural distinction into a package that is difficult to replicate. New luxury inventory arrives regularly, but buildings with authentic architectural pedigree — from practices of BIG's calibre — tend to outperform the broader market over the medium and long term.
