When Islands Records founder Chris Blackwell purchased a 1930s-era Art Deco hotel on Miami’s Collins Avenue in 1997, he had the building reconfigured so that it housed only 45 rooms and suites instead of its original 115. After the hotel changed hands again, in 2004, its new owner, the Kor Hotel Group, began another renovation, which it completed this spring. The Art Deco facade of the 10-story Tides South Beach (www.tidessouthbeach.com) remains, but the hotel’s interior now features an eclectic mix of antique sculptures, hemp-cloth wall coverings, and hammered-brass desks. The 2,500-square-foot, $7,500-per-night penthouse occupies the entire top floor and offers views of Ocean Drive and the Atlantic. . . . At the quieter, north end of Collins Avenue, entrepreneur Giuseppe Cipriani, grandson of the founder of the Hotel Cipriani in Venice, Italy, has broken ground on a condo-hotel. Scheduled to open in 2010, the Cipriani Ocean Resort and Club Residences, South Beach (www.ciprianimiami.com) will feature 65 residences priced from $1 million to $33 million.
