A new £1.7m purpose built respite centre for children with severe disabilities will be built in Leyland or Chorley.
Council bosses have revealed the two locations they are considering for the new Overnight Breaks Unit.
It comes months after Lancashire County Council announced it is closing eight centres but building four new ones.
The services provided at The Bungalow in Preston, Maplewood House in Bamber Bridge, and Long Copse in Chorley will be relocated to the new location.
The council will consult on Lynnhurst in Stanifield Lane, Farington, near Leyland, or Rydal House in Chorley Hall Road, Chorley.
Lynnhurst is a former adult social care facility which was declared surplus in March and Rydal House was a children’s services facility which hasn’t been used since 2007.
The council is due to consult on the sites in November over an eight week period.
A campaign over the future of respite centres in Lancashire has been running for a number of years.
Parents of young people who use or used the centres welcomed the news and said they were “pleasantly surprised.”
Manoj Majhi, whose daughter Amy, 16, attends Maplewood House, said: “It sounds like good news.
“The Leyland site seems like the most logical site to have it.
“It is all about the appropriate distance. My instinct is that Leyland would be the most sensible.
“We hope that the new administration sticks to the plan made my the parents and the previous administration.”
Mr Majhi said he had spoke to a number of parents who were also pleased to hear the news.
Derek Hamer’s son Matthew received care at four-bed centre The Bungalow and campaigned for the new centres to be opened.
He said he is “pleased” that things are moving forward.
However he said: “We were told it would be central Preston.
“There could be a problem if any parents don’t have a car, they might find it hard to get there and back.
“They would have to sort out some sort of transport.”
In March this year it was announced that the centres in Lancaster, Morecambe, Preston, Bamber Bridge, Chorley, Ormskirk, Oswaldtwistle and Burnley would close to make way for the four new centres.
County Coun Matthew Tomlinson, cabinet member for children, young people and schools, said: ““ I’d like to thank the families and staff members who have worked so hard to help us plan the transformation of our residential overnight break service for children with disabilities.
“It’s very exciting to have reached the stage where we are starting to look at locations for the first purpose-built new unit, and I will be following the progress from start to finish with great interest.
“Children and young people with complex disabilities deserve the best service we can give them and I am confident that the new buildings will provide fantastic new facilities for them.”
The changes and relocation of services means that upto 21 residential child care worker jobs will be lost.
A spokesman for Lancashire County Council said it is hoped that compulsory redundancies could be avoided by voluntary redundancy, unfilled vacancies and the wider remit of the new structure.
