10 Wonders of the New China 
10 Wonders of the New China It's a  hotbed of innovative architecture, from diaphanous theaters to buildings  heated and cooled by water 

China  's current building boom is doing more than sucking up the world's  supply of steel -- it's creating a stage for some of today's boldest  architecture and engineering. Take a tour of the 10 of the most  intriguing examples.
1. The Commune, Beijing First phase completed 2002, expansion scheduled for completion in 2010

China  's current building boom is doing more than sucking up the world's  supply of steel -- it's creating a stage for some of today's boldest  architecture and engineering. Take a tour of the 10 of the most  intriguing examples. 
Even  if the Commune didn't sit beside that wonder of the ancient world, the  Great Wall of China , it would still qualify as a wonder. The complex  includes houses by 12 of Asia 's leading architects. It was conceived by  married real-estate developers Zhang Xin and Pan Shiyi, who gave each  architect a $1 million budget. Shigeru Ban, the Japanese architect most  famous for the paper houses he designed for refugees of the Kobe  earthquake, designed the Furniture House, featuring the laminated  plywood typically used for modular furniture, and China's Yung Ho Chang  created the Split House, which takes the idea of a boxy dwelling, slices  it in half, and spreads it out like a fan.
The Commune is now  operated as a boutique hotel by the Germany luxury hotel group  Kempinski, which is responsible for an upcoming expansion, which will  feature 21 homes (including replications of the originals). One element  will remain untouched in the new development: the Commune's private  pedestrian trails, which trace untouched sections of the Great Wall. 
2. Beijing International Airport , Beijing Foster & Partners. Under construction, to be completed in late 2007
 According  to the U.S. Embassy to China, the country will be building 108 new  airports between 2004 and 2009 -- including what will be the world's  largest: the Beijing International Airport, designed by Foster &  Partners. Set to open at the end of 2007, in time for the Beijing  Olympics in 2008, the airport terminal will cover more than 1 million  square meters, giving it a bigger footprint than the Pentagon.
It's  designed to handle 43 million passengers a year initially and 55 million  by 2015, figures that will probably push the new facility into the  ranks of the top 10 busiest airports, going by the 2004 numbers from the  Airports Council International. Given the scale and traffic, Foster  & Partners focused on the traveler's experience, making sure that  walking distances are short, for instance.
Building on Foster's  experience designing Hong Kong 's new mega-airport, the massive Chek Lap  Kok, the sprawling Beijing terminal is housed under a single roof. To  help passengers distinguish between different sections of the vast  space, skylights cast different shades of yellow and red light across  walls -- a subtle but innovative navigational aid. The architects also  kept sustainability in mind: An environmental-control system reduces  carbon emissions, and skylights situated on a south-east axis lessen  solar heat, keeping the building cool. 
3. Shanghai World Financial Center, Shanghai Kohn Pedersen Fox Architects. Under construction, completion scheduled for 2008

Rising  in the Lujiazhui financial district in Pudong, the Shanghai World  Financial Center is a tower among towers. The elegant 101-story  skyscraper will be (for a moment, at least) the world's tallest when  completed in early 2008.
One of the biggest challenges of building  tall is creating a structure that can withstand high winds. The  architects devised an innovation solution to alleviate wind pressure by  adding a rectangular cut-out at the building's apex. Not only does the  open area help reduce the building's sway but it also will be home to  the world's highest outdoor observation deck -- a 100th-floor vista that  will take vertigo to new heights.
4. National Swimming Center , Beijing PTW and Ove Arup. Under construction, completion scheduled for 2008 

The  striking exterior of the National Swimming Center , being constructed  for the 2008 Olympic Games and nicknamed, the "Water Cube," is made from  panels of a lightweight form of Teflon that transforms the building  into an energy-efficient greenhouse-like environment. Solar energy will  also be used to heat the swimming pools, which are designed to reuse  double-filtered, backwashed pool water that's usually dumped as waste.
Excess  rainwater will also be collected and stored in subterranean tanks and  used to fill the pools. The complex engineering system of curvy steel  frames that form the structure of the bubble-like skin are based on  research into the structural properties of soap bubbles by two  physicists at Dublin 's Trinity College . The unique structure is  designed to help the building withstand nearly any seismic disruptions.
5.  Central Chinese Television CCTV, Beijing OMA/Ole Scheeren and Rem  Koolhaas. Under construction, scheduled for completion in 2008

The  design of the new Central Chinese Television (CCTV) headquarters defies  the popular conception of a skyscraper -- and it broke Beijing's  building codes and required approval by a special review panel. The  standard systems for engineering gravity and lateral loads in buildings  didn't apply to the CCTV building, which is formed by two leaning  towers, each bent 90 degrees at the top and bottom to form a continuous  loop.
The engineer's solution is to create a structural "tube" of  diagonal supports. The irregular pattern of this "diagrid" system  reflects the distribution of forces across the tube's surface. Designed  by Rem Koolhaas and Ole Scheeren and engineered by Ove Arup, the new  CCTV tower rethinks what a skyscraper can be. 
6.  Linked Hybrid, Beijing Steven Holl Architects; Li Hu, lead architect.  Groundbreaking on December 28, 2005 , scheduled for completion in 2008 

Linked  Hybrid, which will house 2,500 people in 700 apartments covering 1.6  million square feet, is a model for large-scale sustainable residential  architecture. The site will feature one of the world's largest  geothermal cooling and heating systems, which will stabilize the  temperature within the complex of eight buildings, all linked at the  20th floor by a "ring" of service establishments, like cafés and dry  cleaners. A set of dual pipes pumps water from 100 meters below ground,  circulating the liquid between the buildings' concrete floors.
The  result: The water-circulation system serves as a giant radiator in the  winter and cooling system in the summer. It has no boilers to supply  heat, no electric air conditioners to supply cool. The apartments also  feature gray-water recycling -- a process that's just starting to catch  on in Beijing in much smaller buildings -- to filter waste water from  kitchen sinks and wash basins back into toilets. 
 
7.  Dongtan Eco City, Dongtan Masterplan by Arup, for the Shanghai  Industrial Investment Corp. In planning stages, first phase to be  completed in 2010

Developed  by the Shanghai Industrial investment Corp., Dongtan Eco City , roughly  the size of Manhattan , will be the world's first fully sustainable  cosmopolis when completed in 2040. Like Manhattan , it's situated on an  island -- the third-largest in China . Located on the Yangtze River,  Dongtan is within close proximity of the bustle of Shanghai .
By the  time the Shanghai Expo trade fair opens in 2010, the city's first phase  should be completed, and 50,000 residents will call Dongtan  home-sweet-sustainable-home. The goals to be accomplished in the next  five years: systems for water purification, waste management, and  renewable energy. An infrastructure of roads will connect the former  agricultural land with Shanghai . 
8. Olympic Stadium, Beijing Herzog & de Meuron. Under construction, to be completed in 2008

Sports  stadiums have long followed the enduring design of one of the original  wonders of the world, Rome 's Coliseum. Herzog & de Meuron's  National Stadium in Beijing is an attempt to rethink the classic  sports-arena layout for more ecologically correct times.
The Swiss  architects (of Tate Modern fame) wanted to provide natural ventilation  for the 91,000-seat structure -- perhaps the largest "eco-friendly"  sports stadium designed to date. To achieve this, they set out to create  a building that could function without a strictly enclosed shell, yet  also provide constant shelter for the audience and athletes alike.
To  solve these design problems, they looked to nature for inspiration. The  stadium's outer grid resembles a bird's nest constructed of delicately  placed branches and twigs. Each discrete space within the facility, from  restrooms to restaurants, is constructed as an independent unit within  the outer lattice -- making it possible to encase the entire complex  with an open grid that allows for natural air circulation. The  architects also incorporated a layer of translucent membrane to fill any  gaps in the lacy exterior. 
9. Donghai  Bridge , Shanghai/Yangshan Island China Zhongtie Major Bridge  Engineering Group, Shanghai # 2 Engineering Co., Shanghai Urban  Construction Group. Officially opened in December, 2005
 A  key phase in the development of the world's largest deep-sea port was  completed when China 's first cross-sea bridge -- the 20-mile, six-lane  DonghaiBridge -- was officially opened in December, 2005. Stretching  across the East China Sea , the graceful cable-stay structure connects  Shanghai to Yangshan Island , set to become China 's first free-trade  port (and the world's largest container port) upon its completion in  2010.
To provide a safer driving route in the typhoons and high waves  known to hit the region, Donghai Bridge is designed in an S-shape. The  structure, reported by Shanghai Daily to have cost $1.2 billion, will  hold its title of China's -- and one of the world's -- longest over-sea  bridge for only a couple of years, though. In 2008, the nearby 22-mile  Hangzhou Bay Transoceanic Bridge, which also begins (or ends, depending  on your journey) in Shanghai , will earn the superlative. 
10. National Grand Theater, Beijing Paul Andreu and ADP. Under construction, to be completed in 2008

Located  near Tiananmen Square , the 490,485-square-foot glass-and-titanium  National Grand Theater, scheduled to open in 2008, seems to float above a  man-made lake. Intended to stand out amid the Chinese capital's  bustling streets and ancient buildings, the structure has garnered  criticism among Bejing's citizens for clashing with classic landmarks  like the Monument to the People's Heroes (dedicated to revolutionary  martyrs), the vast home of the National People's Congress, or Tiananmen  Gate itself (the Gate of Heavenly Peace).
French architect Paul  Andreu is no stranger to controversy -- or to innovative forms. A  generation ago, in 1974, his untraditional design for Terminal 1 of  Paris 's Charles de Gaulle airport was criticized for its unusual  curves, yet Andreu's groundbreaking, futuristic building later was seen  to distinguish de Gaulle from more generic European and international  air hubs. (The same airport's Terminal 2E, also designed by Andreu,  gained attention in 2004 when it collapsed, tragically killing four  people.)
Beijing 's daring National Grand Theater is as much a  spectacle as the productions that will be staged inside in the  2,416-seat opera house, the 2,017-seat concert hall, and the 1,040-seat  theater. At night, the semi-transparent skin will give passersby a  glimpse at the performance inside one of three auditoriums, a feature  that highlights the building's public nature.
