Renovations at Brown's hotel in London have hit snags, which will delay its reopening until September.
The cost has also escalated dramatically, from the original prediction of £15m to recent estimates, which now stand at £19m.
The refurbishments, which began in April last year, were meant to be completed by May. Problems with contractors' work falling behind schedule mean there will now be a soft opening in August, followed by an official opening on 1 September.
A Brown's spokesman said: "We are having to do more work than originally envisaged, but this is not unusual given the age of the building. When undertaking a project of this size it's not a long delay."
Stuart Johnson, general manager, added: "It's not scientific - I wish it was. We've got to do this properly and refurbish to a high specification, so we are not cutting corners, but we are now taking bookings for September."
