The adult social care and health committee is set to appoint Kier Construction and Ashley House to carry out the project at its meeting on 29 October.
The Council will be investing £4.1m in the two schemes which will also benefit from a £30m investment from the consortium.
Extra care is an extension to traditional supported housing where older people can live as independently as possible with the reassurance that care staff are on-site for 24 hours a day.
Older people can have different levels of care support dependent on their needs and can buy, part buy or rent an apartment on a complex. They will have their own front door so have their privacy or they can meet other people, friends, family and visitors in the communal areas.
The new developments will have flexible space and communal facilities and services such as a café, hairdressing salon, well-being clinic, fitness room, library and IT studio. They may have falls clinics and links to other health services such as chiropody. People from the wider community will also be encouraged to use the services.
A tendering process has taken place to select the partners to build the two developments which form part of a wider plan to create 160 extra care places for people funded by the council at a cost of £12.65m.
