A major Huddersfield health centre is set to close, forcing services to move.
The Princess Royal Health Centre in Greenhead Road has fallen into a state of disrepair.
Health chiefs say £10m is needed to bring it up to modern standards.
The building is the former maternity hospital where thousands of babies were born.
It opened in July, 1928, as the Municipal Maternity Home.
The last baby was born there in 1984 and the building was then handed over to community health services.
A report says the health centre is of “an age and condition that requires major investment” to bring it up to an “acceptable standard”.
Calderdale and Huddersfield NHS Trust admits it does not have the money to spend on the building due to pressures elsewhere.
It will outline its plans to councillors on the Well-Being and Communities Scrutiny Panel on Thursday.
Council papers say: “The trust has a limited maintenance and capital investment programme and unfortunately investment on this site is not as high a priority as investment required elsewhere in the trust.”
They list specific issues with the health centre, including:
Very poor building environment and condition for patients;
Inadequate energy-efficient systems making it costly to run;
Electrical and mechanical infrastructure beyond expected lifespan;
Inadequate fire protection.
Health services offered from the health centre include a sexual health clinic, termination of pregnancy, hearing clinic, children’s therapies and podiatry, which has the biggest number of patients at 12,258.
Locala, a community health service, is also based at the centre, mainly as a staff base for stop smoking services, school nurses, health visitors and administration services.
There is also a dental clinic and a Macmillan team are based there.
The hospital trust does not have a moving date, but hopes to have a plan in place by October this year indicating its relocation.
The trust is planning a consultation process with patients, families, councillors and service users this summer.
It is also seeking other sites to offer the same services.
The hospital trust’s director of planning, performance, estates and facilities, Lesley Hill, said: “These are proposals as due to the very dated condition and general unsuitability of Princess Royal Health Centre, and the huge, unaffordable costs to make these buildings meet required standards, the trust is starting the process of looking to find more suitable premises for our services which will give a much better environment for our patients and their families.
“As part of this we are starting an engagement process over the summer, where we will speak to our patients, their families and our staff to get their views.”
