Developers are set to be appointed this week for a new house-building scheme in Cardiff and the Vale of Glamorgan.
More than 2,200 homes are due to be built across the region in the next ten years as a result of the partnership between the two local authorities.
Around half of the new homes will be earmarked as affordable properties retained by the two councils for social rent or shared ownership, while the rest will be sold on the open market.
Cardiff Council's cabinet is expected to confirm its preferred development bidder when it meets on Thursday.
Cllr Sandra Perkes, cabinet member for public sector housing, said: "This is an exciting partnership arrangement that will see a large number of houses delivered across the Cardiff and Vale region."
They will be energy efficient and built sustainably, which aligns perfectly with the Vale of Glamorgan Council’s Project Zero Commitment to become carbon neutral by 2030."
"A large proportion will also be council homes, following on from previous house-building schemes to meet growing demand for this type of property."
"The council recently completed work on a council-housing development on Hayeswood Road in Barry, which came after the delivery of similar projects - Llys Llechwedd Jenner, Lon y Felin Wynt and Clos Holm View."
The partnership is the second housing programme in the Welsh capital, following on from the Cardiff Living scheme and forms part of wider development plans - the largest of their kind in Wales - which could see as many as 4,000 new homes in the city, including 2,800 council homes.
Cllr Lynda Thorne, cabinet member for housing at Cardiff Council, said: "Our experience of our first housing partnership provided a strong case for delivering the remaining sites in our development programme via another partnership arrangement."
"This approach has reduced delivery risk and enabled us to get projects on site quicker, as well as unifying the standard of the council homes and homes built for sale by adopting a ‘tenure blind’ approach."
"We are really pleased to be working with the Vale of Glamorgan on this partnership and to have reached the point where we are on the brink of appointing a developer to work with us on delivering more high quality, energy-efficient new homes for Cardiff and the Vale over the next ten years."
"The tender process has been extremely competitive and we are grateful to each bidder for their submissions and participation in the process."
"We now look forward to appointing our development partner, subject to all the necessary due diligence, and replicating the success of our Cardiff Living scheme together in this new Cardiff and Vale Housing Partnership."
The cabinet is also expected to approve the list of specific development sites for the partnership programme when it meets on Thursday.
The report will also be scrutinised by Cardiff Council's community & adult services committee when it meets on Monday afternoon.
