A DEVELOPER is working with ClwydAlyn to deliver 56 energy efficient affordable homes in Flintshire. 

ClwydAlyn is partnering with Castle Green Homes for the scheme in Mynydd Isa.

Full planning permission for the Mold Road scheme in Mynydd Isa was originally granted to ClwydAlyn in January 2021. Castle Green Partnerships stepped in and submitted an application to amend the house types in July 2023, after a previous contractor withdrew from the scheme.

Enabling works started on site in August 2023 and the revised plans were approved in October.

Partnerships director Eoin O'Donnell said: “This is the first site that Castle Green Partnerships will deliver for ClwydAlyn. Initially we were contracted for the construction of the roads and sewers and subsequently agreed to build out the full site, cementing our growing relationship with ClwydAlyn.

"This represents a significant step forward for the partnerships side of our business and brings the total number of affordable homes we are contracted to deliver to more than 900.

“The need for affordable housing has never been greater. We aim to provide well designed, fuel-efficient, high quality affordable homes. The Mynydd Isa scheme will provide a valuable and much-needed contribution to the affordable housing in Flintshire, with a mix of properties for social and and intermediate rent.”

Across the development there will be range of homes from one-bedroom apartments, to two and three-bedroom bungalows, to two and three-bedroom houses.


The first homes will be ready to move into in winter 2024, with the overall development expected to be completed by autumn 2025.

The homes in Mynydd Isa are part of ClwydAlyn ambitious development programme to deliver 1,500 new homes in North Wales by 2025, with an overall expected investment of £250 million.

Penelope Storr, head of development and growth at ClwydAlyn said: “We are pleased to share the news of our collaboration with Castle Green to deliver 56 energy efficient affordable homes. This partnership shows our commitment to sustainable development and delivering high-quality housing options for the community.”

The homes are being built using sustainably sourced, precision-made timber frames. This is a fast, reliable method of building, with lower CO2 emissions created than that of traditional building methods.

The homes will include solar panels and batteries, air source heat pumps and electric vehicle charging points, ensuring that they are energy efficient and cost effective to run.

To support the area's surrounding wildlife, a bat barn will be constructed on site to facilitate roosting for local colonies. There will also be 1.5 acres of open space provided as part of the development, including areas of low seeding mix and planting to benefit the microclimate.
