The Queen may have to move out of Buckingham Palace to allow the historic building to be refurbished at an estimated cost of STG150 million ($A304.9 million).
The famous London landmark needs a total overhaul and the monarch vacating the palace while the work is carried out is one option being considered by Palace officials.
The Queen spends around a third of the year hosting garden parties, receptions, investitures and other events at her official home, which a royal source has described as the “centre of national life”.
The work needed reflects the age of the building, first used as a royal place by Queen Victoria, which has not been decorated since 1952, the year the Queen ascended the throne.
It has old plumbing that is unlikely to be energy efficient, ageing wiring, and a significant amount of asbestos that needs to be removed, in a project described by the royal source as a fundamental “re-service”.
“One option is for the palace to be vacated. We’re getting experts to look at these scenarios and cost them for us,” said the royal source.
“The initial estimate for the refurbishment of Buckingham Palace looks like 150 million refurbishment.”
Buckingham Place has been the Queen’s official London home throughout her reign and for a period before.
The last time she left for any length of time was during the Second World War when she, then Princess Elizabeth, was moved to Windsor Castle with her sister Princess Margaret.
