A government agency will renew its push to have the historic Caldwell House old nurses quarters buildings in Sale Street demolished.
The body in charge of health-related capital works in NSW, Health Infrastructure, owns the buildings but said it had no future use for them.
A spokeswoman for Health Infrastructure said it would re-submit a development application for the demolition to Orange City Council following the first DA in July 2018.
"Following a request for further information from council the documentation was reassessed and updated by expert consultants," she said.
"The DA will be resubmitted in answer to council's queries.
"Once the DA process is further progressed Health Infrastructure will consider the next steps to take."

She said following the closure of the adjacent former Orange Base Hospital in 2011 Health Infrastructure did not need the Caldwell House buildings.
"There is no future health use for the site," she said.
"The vacant building is no longer fit for habitation and requires significant work to meet contemporary standards and building codes.
"In addition the site has been subject to vandalism and safety issues."
In the original DA Health Infrastructure said asbestos was strewn throughout the building following attacks and theft of copper piping and fittings by vandals.
The DA said it would cost $2.4-2.7 million to clean up the asbestos which was potentially more than the site's value.
Even retaining the facades would cost $2.4 million.
It said a developer was close to buying the properties in 2017 for an aged care facility but pulled out once the extent of the damage was revealed.
"In late 2016 and again in mid-2017 whilst the arrangement was in final negotiations, there was a forced entry, theft and vandalism attack on these buildings resulting in significant damage," it said.
However, heritage architect James Nicholson of Adaptive Architects in Orange last year said the cost of asbestos removal should not be a factor in deciding whether to demolish or keep the building as the asbestos would have to be removed before the building could be demolished.
Caldwell House has heritage status under the Orange Local Environment Plan.
A poll conducted by the Central Western Daily last year found 51 per cent of voters were in favour of knocking down the buildings.
