A pair of local authorities are looking for a developer to build £500m of housing in the southern tip of Wales.
Cardiff and Vale of Glamorgan councils this week published a contract notice for their New Housing Partnership.
The successful firm will develop a number of sites across the region over a 12-year period.
The councils intend to enter separate contracts with the developer for each site in the programme.
Works to be delivered could include demolition, site clearance, construction, plumbing, engineering, consultancy and project management, according to the contract notice.
Companies have until 11 December to express an interest, with invitations to tender expected to be sent to up to four firms by February.
More than 1,600 homes were built in Cardiff in the 12 months to 31 March 2023, according to a report evaluating the progress of the city’s Local Development Plan.
This represented the biggest single-year growth for 15 years, according to the council.
Dan De’Ath, Cardiff’s cabinet member for strategic planning and transport, said in October: “The council has been consulting on the preferred strategy for the Replacement Local Development Plan (RDLP) that will shape the development of the city up until 2036.
“As of October this year, there are over 8,000 applications from people looking for housing on the council’s waiting list, so there is a clear need to build homes, especially affordable homes, and 6,000 affordable homes could be delivered through the lifetime of the RDLP.”
