Key Biscayne Luxury Condos for Sale

Beyond the Rickenbacker tollgate, tucked between two state parks, Key Biscayne functions as Miami's island village — a K-8 school and streets where children pedal to the beach. Ordinance limits the condo count and no new building has opened since 2014, which means the scarcity driving prices here is entirely real.

Luxury in a Key Biscayne condo is a specific tier, not a mood — full-floor and half-floor residences, branded towers, private elevator foyers and service that runs like a hotel. In a market known for a family island village between two state parks, fifteen minutes from Brickell, the seven-figure condo segment is where provenance matters most: the developer, the architect, the finish level and how the building has aged move value as much as the address. This page holds Key Biscayne condos priced at $1M and up, sorted so the whole luxury range is in front of you.
