The land on Court Farm, which is surrounded by the green pastures of the Cotswold Way in Gloucestershire, is being donated by local farmer Adam Knight.
There are also plans for changing rooms, a sauna and for drinks to be served.
Organisers of the project are now armed with information about 20 other swimming lakes, marine pools and lidos as well as input from some 850 people who took part in the community survey.
“The main themes were people love swimming, sauna and coffee,” said Ms Morris who stressed that the social element was also important.
“They wanted a nature-rich setting, natural, chemical-free water, use of renewable energy and somewhere open all year round,” she added.
