Planning application has been submitted to transform the former Volkswagen dealership on Tritton Road into a leisure centre.
The proposal is for the building to be used as a gym with an indoor swimming pool and other leisure facilities.
It would be open between the hours of 6.30am and 10.00pm Monday to Friday and 8.00am and 8.00pm Saturday and Sunday.
The premises have been vacant for over three years since the former Volkswagen dealership ceased trading.
The site has the benefit of a 117 space car park.
Plans for the leisure complex are subject to planning approval from the City of Lincoln Council this week.
No objections have been received from any properties in the area.
