Television actor Neil Morrissey is ploughing £5m into renovating his country hotel - after losing £1,375,664 on it in a year.
The Hurst Hotel in Laugharne, Carmarthenshire, will be closed for the revamp until November.
Morrissey, star of BBC comedy Men Behaving Badly, remains confident the hotel will be a success, despite its heavy losses.
His spokesman told the Daily Mirror: "He loves Wales. You have to speculate to accumulate. He is not worried."
The actor is also owner of Brown's Hotel in Laugharne, the Three Mariners pub in the same town and the Hurst House private members' club in London's Covent Garden.
He also plans to spend £7.5m developing the Mill near Letchworth in Hertfordshire into a 24-suite property with his Hurst House business partner, Matt Roberts. It will have a 100-seat restaurant, spa and fitness centre, and will open next year.
