On a recent trip to Miami, I got an exclusive tour of a $48 million three-story penthouse in Miami Beach.

It's the most expensive condo for sale in Miami-Dade County, according to Zillow and Trulia.

The 11,031-square-foot condo, which sits at the top of the 42-story Continuum tower in the South of Fifth neighborhood, is the personal penthouse of real-estate developer Ian Bruce Eichner, founder of the Continuum Company, which built the 42-story tower.

The seven-bedroom luxury apartment includes a 6,091-square-foot private terrace with a pool. It also comes with 10 parking spaces, a beach cabana, and a separate guest apartment on a lower floor.

Eloy Carmenate and Mick Duchon of Douglas Elliman are the listing agents.
