Hotel firm Nine Group has bought the 110-bedroom Noke hotel in St Albans, Hertfordshire, for £9m.
The company, which now owns 13 hotels under various brands throughout the country, will continue to operate the Noke under the Mercure brand for the time being.
In addition to the hotel, it bought a 10-acre plot of land behind it and plans to spend £10m refurbishing the entire hotel and adding an additional 90 beds.
The Grade II-listed building features conference suites/function rooms, a leisure club and spa facility
Vivek Chadha, director and owner of Nine Group, who has grown the company over the past four years, said: "The Noke is a very strategic and long term purchase for our group as we own multiple hotels in the area. We plan to spend close to £10m on refurbishing and development on this hotel to make it a one-stop leisure and business destination. We will be increasing the number of rooms as well as improving the leisure club and conference facilities."
