10 Weirdest Buildings ,These buildings defy conventional architecture and sometimes even gravity!

Cubic houses in Rotterdam, Holland

 The Kubuswoningen, or cube houses, was designed by architect Piet Blom and based on the concept of 'living as an urban roof'. We're not sure what that means, but the cubes are tilted at a 45 degree angle and set upon a hexagonal column. Furthermore, each house is meant to represent a tree, and together in a cluster, resemble a forest. It basically looks like a very abstract tree in Blom's imagination.

Oscar Niemeyer's Museum in Brazil 

This structure looks great as a bigger-than-life art installation, but it is actually a visual arts, design and architecture museum. It has also been nicknamed the 'Museum of the Eye', as the annex resembles an all-seeing beady, black eye. 

 Grand Lisboa casino in Macau, China
 The Grand Lisboa is as auspicious as one can get. The pineapple is associated with money luck and good fortune, so we guess it makes sense to build a casino in the shape of one (or at least try to!). The 58-floor hotel and casino was designed by Hong Kong architects Dennis Lau and Ng Chun Man, and stands at 261 metres.

Atomium in Brussels, Belgium

 The Atomium may not look out of place today, but it was groundbreaking back in 1958. The building, which is a replica of a unit cell of an iron crystal magnified 165 billion times, was designed by engineer André Waterkeyn.
Escalators and a lift allow access between the spheres. CNN may have named it Europe's most bizarre building,

Upside-down house in Terfens, Austria

 One sure way to pique people's curiosity is to completely flip a house upside-down, which is what Polish architects Irek Glowacki and Marek Rozhanski have done. The house serves as a tourist attraction in the western Austrian village of Terfens, where visitors can experience a head-spin - even the interiors are done the wrong way!

The Royal Ontario Museum, Toronto, Canada 

This museum is one of North America's largest. The juxtaposition of its glass and aluminium frame was designed by architect Daniel Libeskind and added to the museum's existing heritage-listed building. Of course, any bold redesign is sure to attract a fair number of detractors, but that hasn't stopped more than a million people visiting the museum every year.

The Longaberger in Newark, Ohio

 This basket building is owned by The Longaberger Company, a manufacturer of wood baskets and other lifestyle products. The company's corporate headquarters takes the shape of their best seller, the 'Medium Market Basket'. It stands seven stories tall, with its handles weighing almost 150 tons. The basket handles can be heated during cold weather to protect against ice damage.

 'Dancing House' in Prague, Czech Republic
 This modernist building was designed by architect Frank Gehry and Vlado Milunić. 99 concrete panels, each a different shape and dimension, support its 'dancing' façade. The Dancing House initially copped flak for standing out amongst the more Baroque or Art Nouveau-styled buildings in the area, but it is now seen as a work of art in Prague.

China Olympics CCTV Tower

 One of Beijing's tallest building, standing at a spectacular 230 meters. The building is considered to be a structural challenge because of its hollow centre. The building attracted controversy when its design was unveiled 11 years ago, but it has given the city's landscape a more futuristic and urban feel.

Hanoi Museum, Hanoi, Vietnam
The Hanoi Museum, designed by GMP Architekten of Germany, incorporates some common themes of museum construction with a new twist.
It resembles an inverted pyramid with four levels of descending squares, the bottom level significantly smaller than even the first floor. This significantly smaller bottom level means that the surrounding gardens and water features almost appear to begin beneath the building leading visitors from the outside in.
