One&Only Residences Key Biscayne A New Oceanfront Residential Development at 301 Ocean Drive
About One&Only Residences Key Biscayne
Overview
One&Only Residences Key Biscayne is the proposed branded residential development at 301 Ocean Drive, the former Silver Sands Beach Resort site. Terra Group and Fortune International are developing the property, with architecture by Touzet Studio. The current program calls for 48 residences, replacing the earlier 56-residence plan associated with the site.
The anticipated mix includes three- and four-bedroom residences and two penthouses. Preliminary information shared on October 14, 2026 indicates three-bedroom residences of approximately 3,860 square feet, four-bedroom corner residences of approximately 4,700 to 5,200 square feet, and pricing from $18 million to $26 million. The two penthouses were indicated at $70 million each.
Demolition and site work have occurred, but vertical construction has not been independently confirmed. Contracts were expected in early November 2026, with completion estimated for the first quarter of 2030. These details are preliminary and should be reconfirmed before a buyer relies on them.

What Makes It Special
Why Buyers Choose One&Only Residences Key Biscayne
One&Only Residences Key Biscayne is worth watching because the combination of new construction, ocean frontage and branded service is difficult to reproduce on the island.
Limited New Oceanfront Supply
Key Biscayne has very little developable oceanfront land and few new condominium projects. That scarcity is the clearest part of the investment case.
Estate-Sized Residences
The preliminary program begins with three-bedroom residences around 3,860 square feet and four-bedroom homes approaching 5,200 square feet.
Branded Residential Service
The proposed One&Only identity would place the project in the branded-residence segment. Final operating details and service charges still need to be reviewed.
A Long-Term Purchase
With estimated completion in Q1 2030, this is best suited to buyers comfortable with a multi-year pre-construction timeline and evolving project documentation.
Advisor Perspective
Our Take on One&Only Residences Key Biscayne
This is an unusually scarce type of offering: a new branded oceanfront development on Key Biscayne, where new supply is limited and most competing condominium inventory is considerably older. The current residence sizes and $18 million starting point put it squarely in the estate-sized, ultra-luxury segment rather than the broader Key Biscayne condominium market.
The most important issue today is not the headline pricing. It is the lack of a final unit-level inventory sheet and complete residence plans. Buyers should compare the eventual layouts, exposures, deposit structure and carrying costs against established oceanfront alternatives before choosing a residence.
The October 14 information is useful, but still preliminary. We would treat the proposed One&Only branding, Q1 2030 completion estimate and current pricing as working sales information until the developer issues final documents.

Key Biscayne — Oceanfront Living Near Brickell
Key Biscayne is a barrier island community that offers privacy, controlled density, and strong residential character within 15 minutes of Brickell and downtown Miami. The island's limited development pipeline, direct ocean frontage, and village-scale lifestyle make it one of South Florida's most distinctive residential markets. Silver Sands sits on the ocean side of the island with direct Atlantic frontage.
Beach & Nature
Key Biscayne offers some of the best beaches in South Florida, including Crandon Park and Bill Baggs Cape Florida State Park at the island's southern tip.
Village & Dining
The Key Biscayne village center offers a walkable, family-oriented environment with restaurants, cafes, and local shops — a stark contrast to the intensity of Miami Beach or Brickell.
Proximity to Miami
Despite its island seclusion, Key Biscayne is remarkably close to Miami's financial and cultural core via the Rickenbacker Causeway.
Schools & Family
Key Biscayne is known for its family-oriented community with highly rated schools, safe streets, and abundant outdoor activities — a primary reason families choose the island over mainland alternatives.

Miami Real Estate Market Intelligence
Market Context: The Miami-to-Northeast and Miami-to-California migration has converted from pandemic-era spike to structural relocation. Miami’s millionaire population grew approximately 78% between 2013 and 2023. Geographic constraint is binding: ocean, bay, and Everglades pin supply. December 2025 medians: Miami Beach condo $620K, Brickell condo $580K. Luxury condominium price per sq ft: $1,200-$3,500+, extending to $2,000-$4,500+ on Fisher Island and $1,800-$4,000+ at South of Fifth.
Value submarkets: Brickell ($600-$1,500/SF), Edgewater ($700-$1,200/SF), Downtown Miami ($600-$2,000/SF). Trophy submarkets: Fisher Island, Sunny Isles Beach ($1,500-$3,500/SF, dense branded-residence inventory), South of Fifth. Branded benchmarks include Four Seasons Surf Club ($2,200-$3,500/SF), St. Regis Sunny Isles ($1,800-$2,800/SF), and Porsche Design Tower ($1,600-$2,400/SF). Miami now carries more hotel-branded residences than any other Western Hemisphere city.
Structural inputs compound: no state income tax (vs. 10.9% NY, 13.3% CA), no estate tax, 78% decade millionaire growth, and construction-cost inflation. Current pre-construction inventory was financed and broken ground before 20-50% tariffs landed on steel, aluminum, concrete, and lumber, effectively the last tranche of pre-tariff pricing. Florida SB 264 restricts acquisitions by nationals of certain countries within 10 miles of military installations and must be screened at contract stage for international buyers.

Miami Real Estate FAQs
What are Miami’s current condominium medians?
December 2025: Miami Beach $620K, Brickell $580K. Luxury condominium stock runs $1,200-$3,500+ per sq ft, extending to $2,000-$4,500 on Fisher Island and $1,800-$4,000 at South of Fifth.
Why is Miami attracting UHNW capital structurally?
Zero state income tax (versus NY 10.9%, CA 13.3%), no estate tax, a 78% decade growth in the millionaire population (2013-2023), and geographic constraints that cap long-run supply. These are structural inputs, not cyclical.
What does the construction-cost tariff environment mean for current inventory?
Current pre-construction inventory was financed and broke ground before 20-50% tariffs landed on steel, aluminum, concrete, and lumber. Replacement-cost pricing on the next development cycle is expected to rise materially. Current allocations represent the last tranche of pre-tariff pricing.
What is Florida SB 264 and how does it affect international buyers?
Florida SB 264 restricts property acquisitions by nationals of seven countries (China, Russia, Iran, North Korea, Cuba, Venezuela, Syria) within 10 miles of military installations. The restriction must be screened at contract stage and may require entity-structure adjustments to comply.
What are typical monthly carrying costs on a Miami condominium?
HOA $0.80-$2.50 per sq ft per month, property tax ~2% of assessed value annually, HO-6 insurance $2,000-$5,000+ annually, flood insurance $500-$3,000+. A 2,000 sq ft condo runs $1,600-$5,000 per month in HOA alone.
What are the post-Surfside inspection requirements?
Buildings 3+ stories must undergo structural inspections at year 30 (year 25 if coastal), then every 10 years. Associations must fully fund reserves; reserve waivers are no longer permitted. Older buildings carry special-assessment risk; inspection and reserve-study review is required at due-diligence.
