Masterplan for Welsh Government to create 375 zero energy in use new homes, educational and community facilities. The 22 ha masterplan, partly encompassing former quarries, retains 4 ha of existing landscape corridor and woodland and further prompts a modal transportation shift through a focus on active travel, enhancement of green travel alternatives and a significant reduction in car spaces. A parallel study was completed in conjunction with the Welsh School of Architecture to explore the delivery of zero carbon development at scale and test the development plan through energy and solar modelling.
