From the Guardian,
The 250-page report details five scenarios ranging from a “do minimum” gradual approach, which would take 32 years, to “a full move out” which would mean that parliamentarians can no longer work in the building for six years. This would cost an estimated £3.9bn.
The most expensive option – a rolling programme of work that would allow the palace to continue to function as a seat of government – would expect to cost £5.7bn in capital expenditure but would take 32 years to complete, the report says. Total costs could rise to £7.1bn and take 40 years in the worst-case scenario, an official confirmed.
The slowest option would mean it would be divided into 12 different zones, each renovated in turn with both chambers being closed for between two and four years at different times.
A mid-option would see MPs and peers vacate the chambers in turn, at a cost of around £4.4bn.
Sell the old building to the highest bidder, knock down Buckingham Palace and put a new parliament there and lease the land around it to developers. Might even make a profit on the deal.
