Selsdon Park passed through several private owners until 1924 when Allan Doble Sanderson bought the house and the accompanying 200 acres (0.81 km2) of land for £13,000.

Improvements and additional rooms were added to the hotel, and in 1985 the leisure complex was completed at a cost of £1.5 million.

On 13 March 1997, Principal Hotel Company purchased the De Vere Selsdon Estate and commenced with a £2.5 million refurbishment, including a new reception area, additional conference and banquet facilities and a business centre.

Dining facilities include the Cedar restaurant, Phoenix grill and bar, and a terrace.
