As part of the development, Vistry will also deliver a 12-flat short term assessment centre for individuals who are neurodiverse.
The design of the centre, which will be operated by Sefton Council, has been shaped by Riverside and those with lived experience of autism and learning disabilities.
The new homes will include houses, bungalows and apartments, providing care options to the local community.
Twenty of the homes will be offered in shared ownership tenure, helping local people to enter the owned property market.
Riverside is delivering the development as part of its £81m strategic partnership with Government agency Homes England.
Work is due to start early this year, with the development expected to be completed by early 2026.
Gemma Hardy, managing director of Vistry Merseyside & Cheshire West, said: “This new development is another great example of the strengths of our business model – where we can operate as both a developer and a contractor – and we’re looking forward to work getting under way early this year.”
