The legendary Italian design house of Salvatore Ferragamo will design the interiors of Trident International's new Dubai-based Pentominium (where expansive penthouses meet the convenience of condo living). The tower for which Ferragamo will design is slated to be the tallest residential building in the world at over 500 meters high. Each floor will comprise one penthouse unit, measuring a luxe 6,500 square feet and offering expansive ocean views.

The building itself will offer a Davidoff-inspired cigar lounge, rooftop observation deck, Swarovski-crystallized grand entrance, indoor pool and spa and fully functional business center. Not that you'd need to leave the tower, but if the need arises, Pentominium residents have use of a fleet of Rolls Royces and Azimut yachts. Residences are expected to be finished by 2012. Though standard units will start at $5.3 million, penthouse list prices have yet to be disclosed.
