The approved application to develop the former coach house, which has fallen into disrepair, would see the building converted into nine two-bedroom apartments and a one-bedroom apartment for short and long-term lets.
The wider plans could see the main building renovated, including a centralised bar, kitchen, separate casual and fine dining areas, and modernised toilets.
Its current conservatory would be demolished to create a “casual drinking and dining destination” with a front terrace.
Mr Martin is also seeking to build an extension containing 23 “luxury” double bedrooms, with an additional two bedrooms to be created in the existing building.
The hotel’s spa, which is currently out of use, would be extended and renovated, creating four additional treatment rooms, a relaxation room, additional changing facilities, a dining area, a gym and sun patio.
Owston Hall began as a medieval manor house. The building was redeveloped and modernised by owner Bryan Cooke and architect William Lindley in the 1700s.
It was redesigned again by his son Philip Davies-Cooke in 1827 and finally sold to a private family in 1976. It was bought by its current owners in 2022.
