Italian shoe designer Salvatore Ferragamo has officially slated plans to design the interior of Trident International’s latest building venture in Dubai. The penthouse tower that Ferragamo will design is predicted to be the tallest residential building in global existence at 500 meters high and will include amenities such as a Davidoff- inspired cigar lounge, indoor pool and spa, business center, and roofdeck. Residents will have the luxury of using a fleet of yachts and Rolls Royce’s. As such, standard units are starting at $5.3 million. Construction is predicted to be completed by 2012.
