An inside look at the new House of Commons

In January, MPswill move across the parliamentary precinct from the Centre Block to the newly renovated West Block.

The building will act as a temporary home for the House of Commons for the next 10 years as the Centre Block closes for construction.

The West Block closed in 2011 for its$863 million makeover.It was the first step in a three-stage revitalization of heritage buildings across the parliamentary precinct.

The renovations doubled the square footage of the West Block and the excavated bedrock could fill 28 Olympic-sized swimming pools.

Besides rehabilitation work on the original West Block, the most striking addition is the permanent courtyard infill and its glass canopy, which will house the House of Commons.

The glass used for the ceiling in the temporary House of Commons chamber is large enough to cover a football field.Some 5,000 assembly parts and 30,000 bolts are being used in the West Block's roof structure.

Similar to Centre Block, seven underground tunnels will connect to the building. There will also be committee rooms and offices inside.
