Work started on the visitor reception building on 9 January 2006 with an original planned completion date of 8 September 2006. It is now expected that the building will open in mid-February 2008.
The original cost for the building as stated in the business case was £8,687,500. Taking into account the delay and remedial work, by 1 November 2007 the cost was estimated at £11,200,000. While this is now expected to be the total cost of the building, some additional equipment will cost up to £250,000. All the costs are shared between the Commons and Lords in the proportion of 60:40.A lessons learnt review will examine the reasons for the delay and cost overrun.
