Historic hospital buildings could be brought back into use for health care for the first time in over 50 years.
They show a care facility and a veterinary practice have been proposed for the Grade 2* listed Huddersfield Infirmary buildings at the mothballed town centre site.
The Victorian infirmary off Portland Street was closed when the all new Royal Infirmary was opened in Lindley in 1966.
A new build NHS medical centre could be constructed on the plot. Discussions are at an advanced stage and details could be revealed later in the summer.
Meanwhile, a deal to build luxury retirement flats on the plot has been done.
The details have been revealed amid the stalled plans to demolish the 1970s college premises and build a new Lidl supermarket.
The start of the scheme was delayed last month after councillors demanded to know more about what would happen to the 19th century buildings on the Edgerton side of the plot before they gave the German food firm the green light.
Some councillors on the Strategic Planning Committee expressed concerns that a supermarket was being built next to historic properties and asked the developer for assurances over what was planned.
The scheme will now be reviewed again by the committee on Thursday.
Developer, Wiggett Construction, confirmed luxury care home firm McCarthy and Stone had signed up to its scheme.
Artist’s impression drawings show the 47 apartment block would sit on what is currently a car park off New North Road.
The new NHS facility would be next door on the corner of Fitzwilliam Street.
The original Huddersfield Infirmary building would be revamped and the Lidl built with its back to Castlegate and its car park facing Trinity Street.
The Grade 2 listed statue of King Edward VII, in front of the former infirmary, would be retained as part of landscaped public gardens.
Mark Sexton, Design and Build Co-ordinator at Wiggett Construction Group Ltd, said: “The Lidl redevelopment would begin with the demolition of the 1970s multi-storey concrete college buildings, opening up the view to the historic infirmary building for the first time in 40 years.
“These buildings would be replaced by a ‘new concept’ Lidl store, to replace Lidl’s Huddersfield Castlegate store on Manchester Road.
“Not only does the Lidl store bring improved shopping and new jobs, it also acts as the catalyst for the regeneration of the whole of the Trinity Central site.
“The supermarket is the essential enabling development, without which nothing on the wider site will be able to progress.
“With McCarthy & Stone now on board and discussions with other suitable operators progressing well, our plans for phase two are now falling into place - and we would be able to consult on these plans later in the year.
“We hope Kirklees Council’s planning committee will seize the opportunity to secure a future for this historic site.”
Wiggett says it will begin demolition of the 1970s offices and classrooms with a matter of weeks, if it gets the green light next Thursday.
The site has been abandoned since Kirklees College moved to its purpose built Waterfront Quarter in 2013.
