The housing secretary has told Bro Radio News that a major net zero housing development will create a "thriving community".
Ministers had previously considered whether to call in the proposals, amid worries from local residents about the impact on the environment and traffic congestion in the area.
But Jayne Bryant insisted she understood residents' concerns about the development - said to be the biggest net-zero project of its kind in the UK - and pledged to continue to engage with the community.
"We very much understand concerns and understand that change can be unsettling for people and we have listened carefully to the views of local residents", she said.
"This development isn't just about building homes - and we need those homes - but it's about creating balanced, sustainable communities that benefit everyone."
"We will continue to engage with the community to make sure that the development reflects local priorities and delivers long-term value for everyone."
The future of the Upper Cosmeston Farm development had been resting on the Welsh Government, who had long deferred a decision on whether to call-in the planning application.
Vale of Glamorgan Council had already approved the proposals and put itself forward to help form a partnership to build the new homes.

Ms Bryant says the scheme will tackle both climate change and housing shortages - with around half of the homes due to be affordable and 219 properties available for social rent.
She said: "With this development, we're creating homes that produce as much energy as they consume - and that is such a big statement."
"But we're not just creating these homes...but the development will also feature a new primary school, green open spaces and a route to promote walking and cycling...it's a vision for those thriving communities."
Developers Barratt Redrow described the project as the "largest net zero community in the UK".
Chief executive David Thomas said: "It will be an exemplar development and a great place to live, with fantastic community facilities, a strong commitment to affordable housing, and cutting-edge sustainability credentials."
"Every highly energy efficient home will be heated by a ground source heat pump and powered by photovoltaic panels and batteries, cutting carbon and bills for future residents."
