The plans were put forward by Pastor Mark Russell from the town's Greenbank Christian Centre.
The proposed changes to the site included turning the building into a community centre with ancillary bedrooms, a restaurant and four self-contained flats. At the town council meeting on Tuesday, Liskeard mayor Anne Purdon said: 'We object because we think that this site is a prime location and one that should be used as a site for a hotel.'
The plans have now been handed to Caradon District Council but will be forwarded to the new One Cornwall council for consideration.
