Full-Floor Living: The Rise of Buying Entire Floors to Create Mega-Residences in Miami

South Florida’s luxury condo market is increasingly defined by scale: adjacent residences and full-floor purchases that are combined into singular “mega-homes” with the services, security, and lock-and-leave ease of premier towers. From Fisher Island to Surfside and Bal Harbour, ultra-high-net-worth buyers are treating vertical living like a bespoke build, shaping layouts early in construction or commissioning complex integrations after closing. The result is a new category of trophy property where privacy, discretion, and hospitality-level operations matter as much as square footage.
