The Parliamentary Service Commission on Thursday handed over the Sh5.8 billion project to the contractor, China Jiangxi Construction Company, marking the start of the project that will take three years to complete.
The proposed building, which includes four basement parking floors and a tunnel connecting to the current Parliament building, will be built on a one-acre plot between County Hall and Continental House where legislators already have offices.
The prime piece of land was allocated to Parliament by the government in 2000.
He said the proposed office block will accommodate the bi-cameral Parliament by creating additional committee rooms and other facilities.
To allow for smooth operations, Mr Muturi said the parking space at the Continental House will be closed with effect from Monday, March 24, and additional parking for legislators will be provided at the Comesa grounds KICC.
Parliament had earlier said it would acquire all the buildings next to it to give way to Parliament’s Square but the plan was later abandoned since the PSC could not meet their asking price.
In June 2012, MPs moved into the new chamber that was refurbished at a cost of Sh960 million – paving the way for refurbishment of the old chamber that will house the Senate.
