301 Ocean Drive is the key upcoming new construction condo on Key Biscayne: 56 planned oceanfront residences on a 3.8-acre site, with private sales expected in Fall 2026. Oceana is the island's newest completed luxury oceanfront reference point. Buyers choosing between them are trading immediate occupancy and known operating history for current-era design, staged deposits, and first selection of a new boutique residence.

The phrase 'Key Biscayne new construction' has a narrow answer. The island is not a Miami mainland district with multiple towers in a rolling pipeline; oceanfront land is limited, and completed luxury buildings already occupy most of the coastline. 301 Ocean Drive is the important new project: a 3.8-acre site, 56 planned residences, and a private sales launch expected in Fall 2026. The right comparison is not new versus old in the abstract, but future specifications and first selection versus immediate occupancy and known facts.
Why New Supply Is Unusual
Key Biscayne is a barrier island connected to Miami by the Rickenbacker Causeway, with a limited land base and a small number of oceanfront addresses. The former Sonesta Beach Resort parcel created an unusually large redevelopment opportunity, but comparable sites are not routinely available.
That makes 301 Ocean Drive a supply event rather than one entry in a long list of competing launches. Buyers should still compare it against completed buildings because a scarce opportunity can be overpriced.
301 Ocean Drive's Planned Program
The project is planned for 56 residences from approximately 3,354 to more than 8,000 square feet, including penthouses with private pools. Architecture is by Touzet Studio and landscape design is by Raymond Jungles. Those facts define the intended product, while final plans, pricing, and amenity documents govern what a buyer can actually contract.
The low residence count is important for privacy and amenity ratio, but it also means fixed operating costs are shared by fewer owners. Compare the lifestyle benefit with the expected HOA budget.
The Pre-Construction Trade
A buyer receives first selection and a chance to choose a residence before public inventory narrows. Capital is paid in stages, commonly beginning near 10% at contract and continuing through construction. The trade is time: delivery is years away, the contract is developer-drafted, and the market at closing cannot be known today.
Completed resale removes construction and delivery uncertainty, but the best stacks may not be listed and older systems can create assessment or renovation risk. Neither path is universally better.
How to Compare the Buildings
Start with location and exposure, then compare exact stacks. Review terrace depth, ceiling heights, elevator privacy, parking, storage, beach route, amenity crowding, assessments, insurance, and rental rules. Building names are a poor substitute for unit-level diligence.
Use closed resale sales as the baseline for existing product and treat pre-launch pricing as a separate premium analysis. Our building comparison guide and pricing guide provide the context before the official 301 Ocean Drive list is released.
The Right Next Step
Registering for 301 Ocean Drive is free and non-binding. It puts buyers on the list for the plan book, price list, and availability before the expected Fall 2026 public release.
At the same time, tour completed island buildings. Seeing Oceana, the Towers, and the Sands in person turns an abstract new-versus-resale decision into a comparison of light, sound, service, beach access, and actual daily life.
