Feilden & Mawson Architects' Supreme Court project could cost £100 million, according to recent newspaper reports.
The project, which will see the historic Middelsex Guildhall transformed into the UK's first Supreme Court, has been the centre of controversy ever since its inception.
This most recent claim, made by the Conservative party and reported in the Evening Standard
, says the cost of the court will cost a 'staggering' £100 million after it emerged that running costs have 'spiralled by £2 million a year'.
The news followed the government announcement that work has started on the high-profile renovation project, which will see the Grade II-listed interior transformed into modern courtrooms.
The official line from the Ministry of Justice states the cost for establishing a Supreme Court is £56.9 million in 'set-up costs' - made up of £36.7 million of renovation costs, which will be paid for by an annual lease charge of £2.1 million.
The Lord Chancellor and Secretary of State for Justice Lord Falconer said: 'The highest court in the land should be open, accessible and independent.
'The Middlesex Guildhall will be transformed into a building suitable for such an important institution and enable the court to take its rightful place alongside its prestigious neighbours on Parliament Square.'by Richard Vaughan
