Cardiff Council has given the green light on development of the capital's new suburb, with building work on new homes to start this month.
The first residents of Plasdŵr are expected to move in during the autumn and will be the founding members of the community in north-west Cardiff.
Developers say the 900-acre site that borders Radyr, Danescourt, Fairwater, Pentrebane and St. Fagans, will be a “world-class, sustainable community”.
The area will include four primary schools, a secondary school, health centres, shops, offices, pubs and restaurants, leisure centres, playing fields and parks and preserved woodland.
Plasdŵr is expected to create over 30,000 jobs during its lifetime, many through the construction phase but also permanent jobs through the education, health, leisure, office and retail space it will install.
