The high-end condo will only have nine apartments, and depending on the unit chosen, there are 3-5 bedrooms and bathrooms in each. Unit sizes range from 2,850 to 7,000 square feet, and one will find a full-floor, duplex, or triplex layout. The floor plan for the penthouse, however, has not yet been released.
