A gym is seeking permission to add a garden spa and sauna building.
David Lloyd Southampton submitted a bid to build a landscaped garden spa on the site off Frogmore Lane.
The proposed site for the new facilities are all located to the south of the club, in an area currently occupied by a tennis court, fighting box and a multi-use court.
The planning application said: “The club currently has very limited indoor spa provision. There have been considerable requests for improvement in these facilities, the proposed works aim to meet these requests.
“It is proposed to build a new spa garden, which will contain a new sauna building.”
He added: “The spa garden has been located in the area currently occupied by the multi-use court and the battlebox.
“This location provides direct access from the existing pool terrace and is positioned to gain the most direct sunlight.
“The existing multi-use court and battle box will be relocated onto the adjacent tennis court.”
A decision is yet to be made by Southampton City Council.
