Buildings at the Castleford, Normanton and District Hospital could be knocked down to build a new Child and Adolescent Mental Health Services (CAMHS) facility.
The plans follow a previous application for 100 homes at the site, which was granted in February.
A planning statement put forward with the application said: “The proposals consist of a part-single/part-two storey building in a series of interconnected blocks.”
It would contain a series of facilities including bedrooms with en-suite bathrooms, consulting and therapy rooms, communal spaces.
There would also be offices, as well as administrative and management space.
The council received seven objections from residents in the Lumley Street area.
They included concerns about the need for traffic-calming schemes in the area, cars blocking people’s driveways, loss of woodland views and potential nuisance.
The 100 homes proposed would have included a mixture of three and four-bed dwelling and be terraced, semi-detached or detached.
In line with the council’s policy, the develop would be required to provide around 30 homes at affordable prices or rent schemes.
A report, prepared by council officers for the previous application, said: “The proposal meets with policy in terms of the principle of development and would have a reduced impact on the highway network.
“Subject to the conditions recommended in the above report, it is considered that an acceptable design and layout could be achieved that would meet with relevant policy and guidance.
