JD Wetherspoon is opening a 14 bedroom hotel alongside its pub, The Bell Hotel, in Market Square, Aylesbury, on Tuesday January 24.
The pub itself will reopen on Saturday January 21.
It is spending £1.1 million on the development, which will create an additional ten jobs.
The new hotel is being housed within the existing undeveloped areas of the first and second floor of the listed building.
In addition the pub is being refurbished as part of the overall project.
Each of the 14 bedrooms will feature an en-suite bathroom, flat screen television with Freeview TV and unlimited Wi-Fi, tea and coffee making facilities, as well as digital air-conditioning and temperature control.
The Bell Hotel manager Zoe Harrison, said: “We are confident that the hotel will be a great addition to the pub.
“We believe it will also benefit the town itself and hopefully it will act as a catalyst for further investment into Aylesbury.”
