Burj Al Arab by Tom Wills-Wright

The Burj Al Arab Hotel (Tower of the Arabs) was designed by Tom Wright in October 1993 and completed in November 1999, in time for the millennium. 

It has been called 'The world's only 7 star Hotel' and is the third tallest hotel in the world.
Burj Al Arab stands on an artificial island (920 ft) from Jumeirah beach and is connected to the mainland by a private curving bridge. The shape of the structure is designed to mimic the sail of a ship.

The design and construction were managed by Canadian engineer Rick Gregory of WS Atkins. Construction of the Island began in 1994. It built to resemble the sail of a dhow, a type of Arabian vessel. Two "wings" spread in a V to form a vast "mast", while the space between them is enclosed in a massive atrium. The architect Tom Wright said "The client wanted a building that would become an iconic or symbolic statement for Dubai; this is very similar to Sydney with its Opera House, London with Big Ben or Paris with the Eiffel Tower. It needed to be a building that would become synonymous with the name of the country."

Several features of the hotel required complex engineering feats to achieve. The hotel rests on an artificial island constructed (920 ft) offshore. To secure a foundation, the builders drove 230 forty-meter-long (130 ft) concrete piles into the sand.

Engineers created a ground/surface layer of large rocks, which is circled with a concrete honeycomb pattern, which serves to protect the foundation from erosion. It took three years to reclaim the land from the sea, while it took fewer than three years to construct the building itself. The building contains over 70,000 m³ (92,000 cu yd) of concrete and 9,000 tons of steel.
