As land in cities becomes scarcer and more valuable, designers and developers are continually pushing for more slender floor plates in tall buildings. Building tall and slender is generally more expensive, but the price tags on luxury apartments make the projects very profitable, the Wall Street Journal reports.
"If you can build more slender and higher, you can get more units with good views—and height is valued," Vancouver developer Jon Stovell told the Journal.
An excerpt from the Journal article:
“While thin towers already crowd the skyline in land-starved cities like Hong Kong, developers elsewhere generally eschewed the slim structures, opting for larger, more stable floors—typically at least 10,000 square feet for tall buildings.
But that's been changing lately. In New York, work has begun on the planned tower at 432 Park Ave., designed by architect Rafael Viñoly, that is expected to have approximately 8,250-square-foot floors and is slated to rise to about 145 feet taller than the Empire State Building. Just one block south of Central Park, the 1,004-foot-tall One57—which saw its crane break during superstorm Sandy—is under construction, with floors as small as 6,240 square feet. And the Cetra/Ruddy-designed One Madison Park, a 597-foot tower with 3,300-square-foot floors, is nearing completion.”
Engineers and architects employ advanced techniques of dampers, steel reinforced concrete and software engineering to produce efficient buildings with reduced columns and fewer residents per floor, the article notes.
"It gives the opportunity for more exclusivity, better views," said Pamela Liebman, president of Corcoran Group, the real-estate company, told the Journal. "I've never had someone say, ‘Can't you show me an apartment with a longer hallway?’"
