Nanyang University’s Green Roof
School of Art, Design & Media, Nanyang University, Singapore
This is a 5-storey School of Art, Design & Media at Nanyang Technological University campus, Singapore. This stunning piece of award-winning architecture is situated in a wooded valley. Before you read on, answer this : is this a landscape or a building? The embracing arms of this unique building have a most spectacular verdant turfed roof which blends with ground contour as if emerges from it. It has glass curtain wall and raw concrete minus the painting. Apart from its visual impact, the turfed roofscape helps to lower the roof temperature and surrounding areas. It works as a functional space, as a scenic outdoor community space via easily accessible sidesteps along the roof edge.
How to get there
By ferry from Puerto Juárez and from Punta Sam; by bus from Mérida or Chetumal to both these ports; by hydrofoil from Cancún.
The Isla Mujeres (Island of Women), 8km/5mi long and up to 2km/1.3mi across, lies in the Caribbean off the coast of the Yucatán peninsula. It offers the visitor beautiful beaches of
Little is known of the island’s history in pre-Conquest days. The Mayas have left traces of their presence in remains of buildings, some of which date from the 8th and 9th c. ad. Most of the temples that have been found are thought to have been dedicated to Ixchel, goddess of the moon and fertility.
The island was discovered in 1517 – two years before Cortés landed in Mexico – by a Spanish expedition under Francisco Hernández de Córdoba, who named it “Island of Women” after the large number of terracotta female figurines which he and his men found in the Maya ruins. In later periods the Isla Mujeres, like most of the Caribbean islands, was a pirates’ and smugglers’ lair. It is only within the last twenty years or so that tourism has come to the island and turned a sleepy fishing settlement into a popular holiday resort. Unlike the neighbouring island of Cozumel and the modern seaside resort of Cancún, Isla Mujeres has remained relatively unspoiled and not too crowded. In order to promote its trade the island has been made a free port.
The island’s main attractions lie on and in the sea and are readily accessible on foot, by bicycle or by moped. The best bathing place is the Playa Cocteros (“Los Cocos”) on the north-west side of the island; and at the northern tip begin the coral reefs which provide such splendid opportunities for snorkellers. The east coast, on the Caribbean, also boasts some beautiful beaches and reefs, such as Playa Ponchol, but strong currents make bathing hazardous.
Here’s a building that should really get your attention when walking pass it. The Dancing House is considered as one of the more real controversial buildings in Prague. The DH was actually designed by a great architect from California, which only proves that he had done some type of hallucinogen while designing it.
The Bank of Asia is a very famous building in Bangkok. It was made way back in 1985, and its robotic appearance is just a symbol of the modernization of banking. It also has the ability to transform into a mega-robot. So, if Godzilla ever decided to show his green face in the land of Bangkok, they would have to fight!
If you saw this picture for the first time, you’d probably thought that it was hit by a massive earthquake. But it wasn’t. In true fashion of the Ripley Legacy, it was built to reflect the odd 1812 earthquake that measured 8.0 on the rick. The building has now become one of the most photographed in the world because of it.
|The Wilson Hall||
This somewhat modernize building was actually built between 1971 and 1974. Its unique design gives the Wilson Hall a great sense of structure, and a prominent landmark for the skyline. The building provides big laboratories, offices, and supports space for over 1500 scientists. And it houses all kinds of strange experiments.
|135 Degree Angle||
This bizarre house really doesn’t have an official name, but it does have a 135 degree angle. So that’s what we’re going to call it. Unfortunately, the only info we have about this house is that it was built in China or Japan. And that it has a silly pink roof. And if you look real close, you’ll notice that its on a 135 degree damn angle.
This hotel’s unique design was directly inspired by the traditional temples in Japan. The Tokyo Sofitel has over 72 rooms, and 11 suites with 3 non-smoking floors. And 5 meeting rooms that includes high-tech boardrooms. Please realize that you have to sell your soul in order to step foot inside this amazing hotel.
We wonder what type of work goes on inside this kind of a building. The unofficial Triangle Building is just a wonder to look at and to ponder over. But, can this be one of the evil headquarters for Scientology or Starbucks? Does this building have triangle bathrooms? There’s so many damn questions!
|The Astra Haus||
The strange building is actually a brewery in Hamburg, Germany. The floors can move up or down on its skinny column core. As of now, the unique building has been destroyed. One of its more famous beer brands was recently bought by a big refreshment corporation. And that beer brand was called Astra.
Take a journey into the unknown with a building called Wonder Works. Its central Florida’s only upside down attraction. And an amusement park for your mind, and your stoner friends. This odd building has over 100 wacky interactive exhibits for your entire family to experience. But make sure you free your weed before coming.
You know that your looking at a real building right? The Crooked House was built in 2004 as an addition at a popular shopping center, and is a major tourist attraction in Sopot, Poland. We just wonder what happens when someone who’s under a controlled substance sees this building for the first time in their life.
Darcons Headquarters by Arquitectura
This modern and unique building architecture called Darcons Headquarters designed by Arquitectura en Proceso as Mexican architects was created many of buildings architecture in Mexico. The building architecture aligned with the road and near from Mexico city. The building architecture in unique and modern design was conceived as a frame that captures part of the landscape and at the same time defines a plane that divides the intercity from the suburbs. This unique building architecture also has skin protector which has a different function first, by using transparant material a living people inside can view scanery freely from that modern and unique building. second funtioan a skin of this modern building architecture protect people who work for from olar irradiance. The operation space is contained within the envelope and flows throughout the building in a three dimensional open plan that honors the hierarchical organization of the company.
Unique building tower in Dubai look like girl dancing this building very luxury and wonderful base material of this building from glasses and was spend a lot of cost, now Dubai as heaven city for celebrities.
The tower’s striking design creates a new presence that punctures the skyline with a powerful recognizable silhouette. The fluid character of the towers is generated through an intrinsically dynamic composition of volumes.
The towers are inter-twinned to share programmatic elements and rotate to maximize the views from the site towards the creek and neighbouring developments.
The design quality of the towers to act as a symbol and icon extends beyond their scale and location. These qualities are derived from the boldness of the architectural concept, from the choreographed’ movement that combines the three towers in one overall gesture and weaves’ with a series of public spaces through the podium, the bridges and the landscape beyond.
The port town of Rotterdam, the second largest city in the Netherlands, lies on both banks of the Nieuwe Maas, the southern arm of the Rhine, here joined by the little river Rotte. At this point, and for a good distance upstream, the Maas is still tidal, with a variation in water level between high and low tide of between 1.2 and 2.5m (4 and 8ft)
Since the opening of the Europoort in 1966 Rotterdam has been the largest port in the world in the volume of goods handled, and in consequence has developed into a gigantic commercial and industrial center whose full growth potential is still very far from being realized. The major imports are oil, mineral ores, grain, timber and fats, the main exports coal and foodstuffs; and Rotterdam is also an important transshipment point for raw tobacco. The city’s principal industries are shipbuilding (with the largest shipyard in Europe), engineering, the manufacture of railroad rolling stock, electrical engineering, petrochemicals (with the largest plant in Europe), semi-luxury foods and tobacco, clothing manufacture and papermaking. Rotterdam owes its rapid development to its fortunate situation on a navigable waterway with access to the North Sea throughout the year without the intervention of any locks. Its seaport can handle ships of up to 90,000 tons with a draught of up to 12m (39ft), and in addition it has the largest inland port in Europe.
Central Rotterdam was almost completely destroyed by German air attacks in 1940. The energetic rebuilding of the city after the war, re-planned with modern shopping streets and residential districts and with numerous high-rise blocks, has made Rotterdam one of the most modern cities in Europe. Around the city center are the districts of Kralingen to the east, Delfshaven to the west and Feijenoord to the south, with an outer ring of suburbs (Overschie, Hillegersberg, IJsselmonde and Pernis) beyond this. Hoek van Holland (Hook of Holland) also lies within the city area; Schiedam, Vlaardingen and Maassluis are independent towns, though closely adjoining Rotterdam on the west. Together with its surrounding satellite towns Rotterdam now forms a highly industrialized conurbation with well over a million inhabitants.
Rotterdam developed out of a settlement founded in early medieval times. A first period of prosperity began in the 13th century, when a dam was built to separate the little river Rotte from the Nieuwe Maas: hence the name Rotterdam. The town received its municipal charter in 1340. Soon afterwards a canal to the Schie linked it with the then important commercial town of Delft, from the prosperity of which it soon began to benefit. This first period of prosperity saw the birth of Rotterdam’s most celebrated citizen, the famous humanist Erasmus (born ca. 1467, d. 1536 in Basle). In 1563 most of the town was destroyed by fire. A new phase of development began, however, in 1585, when many thousands of refugees from the Spanish Netherlands settled in Rotterdam. The manufacture of cloth and carpets in particular brought a further period of prosperity. The port was less important in the 17th century, with only about a fifth of the turnover of the rival town of Amsterdam. The rapid growth of the port began after the split with Belgium, when the Dutch dammed the Schelde (1830-39). The obstacle to the passage of large vessels by the steady silting up of the Maas estuary was removed in 1866 by the construction and constant deepening of the Nieuwe Waterweg, and at the point where it reached the North Sea the new suburb of Hoek van Holland (Hook of Holland) came into being.
This is a very unique building! The Crooked House was built in 2003. What inspired the architects were Per Dahlberg‘s drawings. You’ll found numerous beauty shops and stores inside along with the branch office for RMF radio broadcasting company. It lies in the Bohaterów Monte Cassino street, the town’s most prominent promenade.

Yea yea, I know… It’s not a house, it’s a statue. However it’s unusual, unique and still a peace of architecture.
Rod Mickleburgh in his article (May ‘08) wrote: “It was too hot for New York City; too hot for Stanford University. But a controversial, imposing sculpture by renowned international artist Dennis Oppenheim finally found a public home in laid-back Vancouver.”
It was too hot for Vancouver as well…:) The project has been removed from the city, and is now in Calgary, Alberta.

5. Puzzling World Lake Wanaka (Otago, New Zealand)
(Image credits: Somerslea)
Stuart Landsborough’s Puzzling World is a tourist attraction near Wanaka, New Zealand. It started out as just a maze in 1973, but over the years expanded to accommodate a “puzzling café” where guests could try out several puzzles, rooms with optical illusions, the and other things.
One of the biggest attractions is the leaning tower. The Leaning Tower of Wanaka is, as the name implies, a tower that is seemingly impossibly balanced on one corner, making the whole structure lean at an angle of 53 degrees to the ground. Exactly how this is achieved is yet to be unveiled, but it can be assumed that some kind of counterbalance or anchoring device has been used.

6. Low impact woodland house (Wales, UK)
Once in a while you find something really amazing on the web. And I’m really happy that someone sent us a link of this truly astonishing house.
One guy with the help of his father in law and friends built this house for his family. “The house was built with maximum regard for the environment and by reciprocation gives us a unique opportunity to live close to nature.” he says.
This building is one part of a low-impact or permaculture approach to life. This sort of life is about living in harmony with both the natural world and ourselves, doing things simply and using appropriate levels of technology.
When asked why he is doing this, he gave this answer: “ It’s fun. Living your own life, in your own way is rewarding. Following our dreams keeps our souls alive.”

Aqua is an 86-story mixed-use residential skyscraper in the Lakeshore East development in downtown Chicago.Designed by a team led by Jeanne Gang of Studio Gang Architects, the building is the tallest in the world to have a woman as lead architect, at 859 ft (262 m). It includes one level of parking below ground. The building’s eight-story, 140,000 sq ft (13,000 m2) base is topped by a 82,550 sq ft (7,669 m2) terrace with gardens, gazebos, pools, hot tubs, a walking/running track and a fire pit. Each floor covers approximately 16,000 sq ft (1,500 m2). The Aqua was named the Emporis Skyscraper Award 2009 skyscraper of the year and was shortlisted in 2010 for the biannual International Highrise Award.
Aqua is designed by Jeanne Gang, principal and founder of Studio Gang Architects, and it is her first skyscraper project. This is the largest project ever awarded to an American firm headed by a woman.Loewenberg & Associates are the architects of record, led by James Loewenberg.
The Aqua Tower is located on the 200 block of North Columbus Drive, and is surrounded by high-rises. To capture views of nearby landmarks for Aqua’s residents, Gang stretched its balconies outward by as much as 12 feet (3.7 meters). The result is a building composed of irregularly shaped concrete floor slabs which lend the facade an undulating, sculptural quality. Gang cites the striated limestone outcroppings that are a common topographic feature of the Great Lakes region as inspiration for these slabs.
The building will contain 55,000 square feet (5,100 square meters) of retail and office space, in addition to 215 hotel rooms (floors 1-18), 476 rental residential units (floors 19-52), and 263 condominium units & Penthouses (floors 53-80). Aqua will also be the first downtown building to combine condos, apartments and a hotel. Strategic Hotels & Resorts had agreed to acquire the first 15 floors of hotel space upon completion of the building, but terminated its $84 million contract for the space in August 2008, citing significant changes in the economic environment.
The name ‘Aqua’ was assigned to the building by Magellan Development Group LLC. It fits the nautical theme of the other buildings in the Lakeshore East development, and is derived from the wave-like forms of the balconies; the tower’s proximity to nearby Lake Michigan also influenced the name.
Sustainability was an important factor in Aqua’s design. Gang and her team refined the terrace extensions to maximize solar shading, and other sustainable features will include rainwater collection systems and energy-efficient lighting. The green roof on top of the tower base will be the largest in Chicago. The tower will seek LEED certification.
Ranking criteria and alternatives
The non-profit, international organization Council on Tall Buildings and Urban Habitat (CTBUH) was formed in 1969 and announces the title of “The Worlds Tallest Building” and sets the standards by which buildings are measured. It maintains a list of the 100 tallest completed buildings in the world. The council currently ranks Burj Khalifa as the tallest at 828 m (2,717 ft). The CTBUH only recognizes buildings that are complete, however, and some buildings listed within these list articles are not considered complete by the CTBUH.
In 1996, as a response to the dispute as to whether the Petronas Towers or the Sears Tower was taller, the council listed and ranked buildings in four categories:
- height of structural or architectural top
- height of highest floor
- height to the top of roof (removed as category November 2009)
- height to top of any part of the building.
Spires are considered integral parts of the architectural design of buildings, to which changes would substantially change the appearance and design of the building, whereas antennas may be added or removed without such consequences. This naturally hurts the rankings of buildings without spires, or with antennas instead of spires, or with shorter spires. The most famous such discrepancy is that Petronas Towers, with their spires, are ranked higher than the Willis Tower(formerly Sears Tower) with its antennas, despite the Petronas Towers’ lower roofs and lower highest points (of spire/antenna).
However, this type of discrepancy has happened before, without resulting in a change of the criteria used to determine the world’s tallest building, which until 1996 was the height to the top of the tallest architectural element (spires, but not antennae). A famous historical case of this discrepancy was the rivalry between 40 Wall Street building (then known as the Bank of Manhattan Building) and the Chrysler Building. The Bank of Manhattan Building employed only a short spire and was 927ft (283m) tall and had a much higher top occupied floor (the second category in the 1996 criteria for tallest building). In contrast, the Chrysler Building employed a very large 125ft (38m) spire secretly assembled inside the building to claim the title of world’s tallest building with a total height of 1048 feet (319m), despite having a lower top occupied floor and a shorter height when both building’s spires are not counted in their heights. Upset by Chrysler’s victory, Shreve & Lamb, the consulting architects of 40 Wall Street, wrote a newspaper article claiming that their building was actually the tallest, since it contained the world’s highest usable floor. They pointed out that the observation deck in the Bank of Manhattan Building was nearly 100 feet (30m) above the top floor in the Chrysler Building, whose surpassing spire was strictly ornamental and essentially inaccessible. At present the issue of criteria is moot, as Burj Khalifa tops the list by some margin, regardless of which criterion is applied.
Tallest skyscrapers in the world
Buildings that were at any time the tallest in the world are shown in boldface. The list includes the tallest 250 buildings in the world.
Height to roof
Some skyscraper aficionados prefer height to roof to determine tallest building in the world, as “architectural feature” is regarded as a subjective and less-fair measure. In November 2009, the CTBUH stopped using the roof height as a method of measurement for tall buildings.
Height to pinnacle (highest point)
This measurement disregards distinctions between architectural and non-architectural extensions, and simply measures to the highest point. This measurement is useful for air traffic obstacle determinations, and is also a wholly objective measure. However, this measurement includes extensions that are easily added, removed, and modified from a building and are independent of the overall structure.
This measurement only recently came to use, when the Petronas Towers passed the Sears Tower (now called Willis Tower) in height. The former was considered taller because its spires were considered architectural, while the latter’s antennae were not. This led to the split of definitions, with the Sears Tower claiming the lead in this and the height-to-roof (now highest occupied floor) categories, and with the Petronas claiming the lead in the architectural height category.
