South Kesteven District Councillors have unanimously approved a new art gallery in the grounds of Grimsthorpe Castle.
The proposals from the Grimsthorpe and Drummond Castle Trust were given high praise by members of the planning committee on Wednesday.
The Grade I listed Castle is home to Baroness Willoughby de Eresby whose family have lived there since the 16th century.
The proposed gallery will house Lady Willoughby de Eresby’s personal collection of artworks.
The new gallery will be built near to the Old Coach House and will include alterations to the Grade II listed building as well as improvements to existing visitor facilities.
The Old Stables will become a new cafe, while a new 270-space visitor car park will also be created.
Councillor Judy Smith said the plans would “bring to this part of South Kesteven a build which will be of excellent design, a great visitor attraction and great plus to the local economy”.
Councillor Robert Reid said: “What a wonderful operation this could be for future visitors. It is one of a great magnitude and to be heralded.”
Councillors also praised the environmental benefits which will include carbon reduction methods and said a recent site visit demonstrated the enthusiasm of staff on the site.
