Which of the following is also known as the houses of parliament ? ?

The new Palace of WestminsterIn 1834 a fire destroyed the Palace of Westminster, leaving only the Jewel Tower, the crypt and cloister of St. Stephens and Westminster Hall intact. After the fire, a competition was organized to create a new building for the two houses of parliament. 

A design by Sir Charles Barry and his assistant Augustus Welby Pugin was chosen from ninety-seven entries. They created a large but balanced complex in neo-Gothic style and incorporated the buildings that survived the fire. The whole complex was finished in 1870, more than thirty years after construction started. It includes the Clock Tower, Victoria Tower, House of Commons, House of Lords, Westminster Hall and the Lobbies.
