The partners will help tackle growing housing demand across the city by delivering more than 1,000 extra new homes by 2027.
At least 40% of ‘Cardiff Living’ homes in phase 2 and 3 will be earmarked for council rent or sale via the authority’s assisted home ownership scheme.
Cardiff Council and Wates Residential are looking to install ground source heat pumps, solar PV panels and batteries on all of the new homes.
As part of the partnership, Cardiff Council and Wates Residential have made a joint pledge to create employment and training opportunities for local residents.
This includes the creation of 71 on-site apprenticeships, 147 work experience placements and a ‘Building Futures’ programme providing construction and employment skills training for unemployed adults.
Edward Rees, Regional Director for Wates Residential, said: “Since 2015, our award-winning partnership with Cardiff Council has delivered 343 much-needed new homes for local people across Cardiff.
“Starting the process for the next two phases of the programme is an exciting step forward for Cardiff Living.”
The first new developments have now started on site and include the largest single Cardiff Living development to date at the former Eastern High School site in Rumney.
The site will see 214 new homes developed, including 44 Community Living flats for older people at Addison House.
