Plans to develop a luxury hotel on Drake's Island off the south Devon coast have been dealt a blow by planners.
Developer Dan McCauley has proposed a £10 million scheme to redevelop the historic island overlooking Plymouth Sound and the Hoe.
But Plymouth city councillors yesterday reluctantly turned down an application by Mr McCauley's company Rotolok.
The council's planning committee was advised by officers to refuse because environmental surveys of the island and surrounding sea were missing or incomplete.
Drake's Island is a Scheduled Ancient Monument, has Grade II-listed buildings and is home to protected bats and little egrets.
The councillors were told that environmental surveys needed to be carried out in the summer. Legal officer David Shepperd told the committee that approving the application without the necessary environmental surveys would open the council to legal action by anyone from residents and the developer to wildlife groups.
Plans include a 44-bedroom boutique hotel, a bar, restaurant, swimming pool and spa. The complex would also have a jetty and ferry service with limited public access.
