Exciting news for Penarth! Plans for the largest net-zero housing development in the UK are moving forward. The Welsh Government has teamed up with Barratt Redrow to bring 576 eco-friendly homes to Upper Cosmeston Farm, just a stone’s throw from the stunning Cosmeston Lakes Country Park. This project promises to set a new standard for sustainable living in Wales, tackling housing shortages while staying green.

Not without controversy, the development has sparked concerns among locals about traffic, green space, and the strain on local services. But the government is eager to create thriving communities and drive climate action. Cabinet Secretary Jayne Bryant says it’s not just about building homes; it’s about investing in a sustainable future. Plus, the project is set to offer training and apprenticeships, shaping careers for the next generation.


While the idea of adding hundreds more people to the area has raised eyebrows, particularly with worries over school and healthcare availability, there’s a bright side too. Plans include a primary school and public spaces, with hopes to address the local health service needs down the line.
The housing market in the Vale of Glamorgan is under pressure, with over 7,000 households waiting for council housing as of March 2025. Thankfully, 219 homes will be available for social rent, offering some relief to those in need.
This development might just be the game-changer Wales needs. What do you think about the new plans? Is it a step forward, or are the concerns too significant to ignore? Share your thoughts!
