Planning permission has been granted for four extra bedrooms to be built at The Cavendish Hotel, Chatsworth.
The coach house, adjacent to the hotel, will be converted into the new space, with local architects Haxton Koyander of Chesterfield appointed to design the plans.
Planning permission has been granted to extend the building to the east and south of the property, which in recent years has been a single dwelling under tenancy.
Local architects Haxton Koyander of Chesterfield have been appointed to draw up the plans, while the interiors will be led by Rachel Maclane in conjunction with the Duchess of Devonshire.
Antiques expert Jonathan Bourne has been tasked with sourcing furniture and objects of interest to complement the overall design.
A ground floor bedroom will be equipped for access by wheelchair users, and all bedrooms will have full use of the facilities within the main house of the hotel.
The Cavendish will also offer the coach house on an exclusive use basis if required.
Managing director, Philip Joseph said: “The coach house is adjacent to the hotel’s Grade-II listed building and as such it is important we maintain its integrity and safeguard the historical importance. Gaining an extra four bedrooms will add value to our facilities and I see these rooms becoming very popular. Throughout the building process the work will be discreet and it is intended they will be ready for the autumn.”
