Icon South Beach Floor Plans | 1 to 4 BR & Penthouse Guide | 450 Alton Road SoFi

Icon South Beach — Floor Plans

At 450 Alton Road in Miami Beach's South of Fifth neighborhood, Icon South Beach is the building that established the residential design standard for SoFi — completed in 2005 by Related Group and designed by Sieger Suarez Architects with interiors and common areas by Philippe Starck through Yoo Ltd / Yoo Studio, Icon South Beach delivered the first Starck-branded residential tower in South Florida and set the aesthetic benchmark that has influenced every South Beach luxury condoMore Info building constructed in SoFi since. The address at 450 Alton Road places the building on the direct approach to South Pointe Park — the same street that runs toward Apogee South BeachMore Info and Five Park Miami BeachMore Info to the south.

The building is a contemporary two-tiered residential tower rising 35 and 40 floors respectively — an S-shaped dual-tower configuration on a seven-acre site with 1,000 linear feet of Biscayne Bay waterfront. The S-shape is not aesthetic; it is structural: the building's curve was specifically designed to maximize bay and ocean views from the widest possible number of residences simultaneously, rotating floor plates so that every unit in both tiers captures at least a partial water view from its primary living areas.

The Philippe Starck Grand Lobby — 20-foot soaring ceilings, a 40-foot reception desk enshrouded in a semicircle of white curtains, and a dramatic chandelier above — remains one of the most theatrical residential arrivals in Miami Beach over two decades after its delivery. Every time a resident returns home to Icon South Beach, they pass through a space that was designed by one of the world's most celebrated designers at a moment when that level of residential lobby investment was genuinely unprecedented in South Florida.

Icon South Beach — Floor Plans at a Glance

The S-Shaped Tower — Why the Architecture Defines Every Floor Plan's View

The S-shaped profile of Icon South Beach's two-tiered structure — rising to 35 floors on the lower tier and 40 floors on the upper — is the single architectural decision that most directly shapes the floor plan experience at this building. The curve of the S-shape rotates the building's floor plates at different orientations as the structure winds from north to south along the Alton Road site, producing:

Bay-facing and ocean-facing floor plans across all floors. The S-curve's rotation means that both the 35-floor and 40-floor components of the building have primary exposures pointing toward either Biscayne Bay (west) or the Atlantic Ocean / South Beach cityscape (east) — giving buyers a genuine choice of view orientation across a wide range of floor levels without sacrificing view quality in either direction.

No single-exposure floors. The S-shape eliminates the conventional problem of a straight slab tower — where one face has the primary view and the opposite face is a secondary city view or an obstructed outlook. At Icon South Beach, the curve of each floor plate produces angled exposures that capture elements of both the bay and the city or ocean on all but the most interior-facing rooms.

The building is identifiable from across Biscayne Bay. The S-shape makes Icon South Beach one of the most recognizable buildings on the South Beach waterfront from the water — the curve is visible from the causeway, from boats on the bay, and from the MacArthur Causeway — giving the building a skyline presence that reinforces the address identity for residents and their guests.

1 Bedroom Residences — 851 to ~1,050 Square Feet

One-bedroom floor plans at Icon South Beach range from 851 to approximately 1,050 interior square feet — the building's entry configuration and its most actively traded investment tier. At this square footage on the SoFi bayfront, the one-bedroom Icon floor plan delivers:

• 9-foot ceilings with floor-to-ceiling sliding glass doors throughout
• Private oversized balcony with glass railings — the glass railing standard was relatively unusual in South Florida residential construction at the time of delivery and adds meaningful view quality from the seated interior position
• Choice of bay or ocean views depending on specific unit orientation within the S-curve
• Miele kitchen appliances with European cabinetry — a specification that at the time of delivery in 2005 was meaningfully above the luxury standard in the South Beach residential market
• Choice of granite or marble countertops
• Choice of four Philippe Starck interior color schemes — a buyer customization option that reflects Starck's view that residential interiors should reflect individual identity rather than a single mandated palette
• Kohler fixtures and whirlpool tubs in select configurations
• Imported porcelain or marble flooring throughout

The four Starck color schemes are one of the building's most enduring differentiators in the SoFi resale market — residents who originally selected different color schemes means that no two Icon South Beach interiors are necessarily identical even within the same floor plan configuration. For buyers specifically interested in a Starck-designed interior rather than a generic renovation, finding a unit that retains its original color scheme is a meaningful floor plan consideration.

2 Bedroom Residences — 1,200 to 1,750 Square Feet

Two-bedroom floor plans range from approximately 1,200 to 1,750 interior square feet — the building's most active resale tier for owner-occupiers and investors who want meaningful accommodation beyond a pied-à-terre. Multiple view orientations are available within the two-bedroom collection: bay-facing units look directly west across Biscayne Bay toward Key Biscayne, while ocean-facing and city-facing units capture the South Beach skyline and the approach to South Pointe Park.

All two-bedroom residences include walk-in closets, the full Miele appliance suite, and private oversized balconies. The S-curve building geometry means that corner-positioned two-bedroom units — available at the inflection points of the S-shape — capture the building's most dramatic dual-water views simultaneously. These corner configurations are among the most sought-after resale floor plans in the building and consistently command a premium over comparable interior-facing two-bedroom configurations.

3 Bedroom Residences — 1,750 to 2,158 Square Feet

Three-bedroom floor plans represent the building's most spacious standard configurations, ranging from 1,750 to 2,158 interior square feet — delivering meaningful scale within a 40-story tower that was, at its delivery in 2005, among the largest residential buildings in South of Fifth. Expanded terraces in the three-bedroom configurations — notably generous relative to the floor plan scale given the building's bayfront waterfront depth — provide outdoor living rooms that are disproportionately large relative to the interior square footage. For buyers who want the South Beach penthouseMore Info experience without the penthouse price, upper-floor three-bedroom units at Icon South Beach consistently represent the most value-efficient path to panoramic water views in the SoFi market.

4 Bedroom and Penthouse Residences — 2,158 to 4,000+ Square Feet

Icon South Beach's floor plan range extends to four-bedroom configurations and penthouses at over 4,000 square feet — the building's crown floor plans with panoramic views of the Atlantic Ocean, Biscayne Bay, South Pointe Park, and the Miami skyline simultaneously. At the penthouse level, the S-shaped tower's geometry produces view angles that are unavailable at any standard residential floor below — the full arc of the building's curve is visible from the terrace, and the panorama extends from the Port of Miami and Government Cut to the south all the way to the Venetian Causeway and the Design District in the north.

The Nine Design Selections — Understanding the Starck Specification

Icon South Beach's nine distinct floor plan configurations are organized around nine design selections — a terminology specific to this building that refers to a combination of floor plan layout and interior finish package. Within each configuration, buyers at the time of original delivery could select from four Philippe Starck-designed interior color schemes, producing a total matrix of floor plan and color options that Starck described as allowing each residence to express its owner's individual identity rather than a building-wide aesthetic mandate.

The four color schemes remain visible throughout the building's resale market today — units that retain their original Starck color scheme carry a specific design identity that renovation-neutral units do not. For buyers who are specifically drawn to the Starck aesthetic rather than to a generically renovated luxury interior, verifying the original color scheme preservation status of a specific unit is a floor plan consideration with no equivalent at any other building in this MPE series.

The overall finish standard across all nine design selections includes:

• 9-foot ceilings throughout all living and bedroom areas
• Floor-to-ceiling hurricane-impact tinted glass windows and sliding doors
• European cabinetry in kitchens and bathrooms
• Miele appliance suite
• Choice of granite or marble countertops
• Kohler fixtures throughout bathrooms
• Whirlpool tubs in select configurations
• Walk-in closets in all bedroom suites
• Private oversized terraces with glass railings
• Marble or high-quality porcelain flooring throughout

The Philippe Starck Grand Lobby — Two Decades Later

The Philippe Starck Grand Lobby at Icon South Beach — 20-foot soaring ceilings, a 40-foot reception desk enshrouded in a semicircle of white curtains, and a dramatic chandelier — was the most discussed residential lobby in Miami Beach at the time of delivery and remains one of the most distinctive in the city twenty years later. The lobby's elongated reception desk, wrapped in its theatrical curtain, is a Starck signature that operates simultaneously as a functional check-in point and as a stage set — the beginning of a designed experience that Starck intended to continue into each individual residence via the color scheme selections. At a time when most luxury residential lobbies in South Florida were marble slabs and security desks, Starck's Icon lobby established an entirely different category of residential arrival.

The 1,000-Foot Bay Waterfront — Seven Acres in South of Fifth

Icon South Beach's seven-acre site with 1,000 linear feet of Biscayne Bay waterfront is the second-largest bayside residential land holding in South of Fifth after Continuum's 12-acre beachfront compound — and the only one with a Philippe Starck design pedigree. The seven-acre site encompasses:

• Two infinity-edge pools — a heated bay-facing lap pool and an infinity-edge bayfront swimming pool, both positioned directly on the bay waterfront
• Bay-view café — a resident café with direct views across Biscayne Bay and the Miami Beach Marina
• Whirlpool spa on the water's edge
• A seven-acre landscaped ground plane that connects the tower's base to the waterfront without the compressed pool deck approach common to narrower-footprint buildings

The combination of the 1,000-foot bay waterfront and the seven-acre site means Icon South Beach residents experience the bay from their amenity level in a way that is closer to being on the water than to being in a building that happens to face the water. The pool-to-bay visual connection at the infinity edge is one of the most compelling daily amenity experiences in the SoFi residential market.

The SoFi Context — Where Icon Sits in the Neighborhood

Icon South Beach at 450 Alton Road sits at the northern end of South of Fifth — closer to the David neighborhood and Sunset Harbour to the north, and two to three blocks from the SoFi restaurant corridor along South Pointe Drive. The building is positioned to the west of the SoFi island's centerline — meaning its primary view is bayward rather than oceanfront, a position that gives it a visual relationship to the water that is calm, wide, and perpetually sunset-oriented rather than the wave-facing eastern exposure of Continuum South BeachMore Info and ApogeeMore Info to the south.

Five Park Miami Beach — the newest building in SoFi and the subject of this MPE series' opening floor plan page — sits a single block to the south of Icon on the same Alton Road. For buyers comparing the two buildings as alternative SoFi bayfront addresses, the primary distinctions are generational: Five Park delivers newer construction at a higher price per square foot and carries the Canopy Club amenity program and the 3-acre Canopy Park; Icon South Beach delivers the Starck design legacy, the 1,000-foot waterfront, the seven-acre site, and a 20-year resale track record that provides meaningful price-per-square-foot transparency.
