Plans have been submitted to turn Crockstead Farm Hotel, just outside Uckfield, into a care home.
An application for change of use affects only 13 existing hotel rooms housed in a single block, next to the car park, on a bigger five acre site.
A statement submitted with proposals says the rooms already provide all the facilities that are necessary.
A central dining room, kitchen, lounge and games room are available within the footprint of the building and additional accommodation is available on the site for visiting family members.
The statement says the applicant, Lynn Ascroft, owns and runs three other similar care homes in the Wealden District Council area and so is well-versed on the management of such establishments.
Additional staff would be recruited locally for the operation.
The plans do not involve any increase in footprint, bulk or volume and can be achieved without the need for external alterations.
Two comments in support of the planning application have, so far, been received by Wealden Council.
