Seven members of the government Planning Committee have unanimously refused another application for the former Nude Dunes restaurant in St Ouen's Bay.
The building at La Pulente has been empty since late 2023, when Nude Foods ceased trading in Jersey.
Nude Dunes had only been open for four months before the announcement of its closure.
Revised plans included a modified layout for a two-bedroom self-catered holiday let, with a car parking space, and adjoining beach café.

Nadia Miller, who owns the building, also wanted to see a pergola added to the café terrace for additional shelter.
However, the committee agreed that it is not an appropriate addition to the site, which is in an 'extremely sensitive area' that needs a 'high degree of protection'.
On the subject of the public toilets, Ms Miller told the Planning Committee that a 'private individual' cannot get insurance for public toilets.
This means one of the only ways they can be reopened is if a business takes over the building, or it is used for another purpose, such as a café.
A previous application was rejected. That decision was taken to appeal, but the challenge was dismissed by the Environment Minister in May.
