John Portman, the architect and developer who designed the Detroit Renaissance Center in the post-riot era, revolutionized hotel designs with soaring futuristic atriums and built commercial towers that revitalized the downtowns of decaying postwar American cities, died Friday in Atlanta at age 93, The New Times writes.
The family gave no cause of death. Robert McFadden of the Times writes:
One of the world’s best-known and most influential architects, Mr. Portman, over a half-century, redefined urban landscapes in the United States. He built the Peachtree Center in Atlanta, the Embarcadero Center in San Francisco, the Renaissance Center in Detroit and scores of hotel, office and retail complexes in New York, Los Angeles, Chicago, Houston, Fort Worth, San Diego and other cities.
His buildings often evoked oohs and aahs from the public, but were not always a hit with critics, who called them concrete islands, self-contained cities within cities — serving their patrons yet insular, even forbidding to outsiders. But by combining architectural talents with the savvy of a real estate entrepreneur, Mr. Portman was hugely successful and a rarity among contemporaries: both an artist and a tough businessman.
In the 1960s and ’70s, his signature hotels — skyscrapers with escarpment atriums, cantilevered balconies overlooking interiors big enough to contain the Statue of Liberty, whooshing glass elevators, waterfalls, hanging gardens and revolving rooftop restaurants — offered thrilling antidotes to the standard lot of dreary hotel lobbies, claustrophobic box elevators and shotgun corridors lined with cells for the inmates.
