Cardiff may see 800 environmentally friendly homes built in Pontprennau, which will create Wales' first eco village. Within the proposed village will be a school, shops, community centre and woodland area. All of this will be situated on farmland to the east of the suburb of Pontprennau, next to the River Rhymney.It is thought the houses will use 30% less energy than your typical home. Green technologies will be incorporated in the design stage of the homes which include in between two and five bedroom houses. Some of the green technologies will include rainwater harvesting, wind turbines, ground source heat pumps and hot water solar panels. The proposed estate covers 60 acres of a 100 acre site but maybe in doubt because of differences between Cardiff Council and the Assembly Government Inspectors over the Local Development Plan. The LDP judges how Cardiff will develop until 2021.The main difference between the two is that Cardiff Council wants to develop on previously developed brownfield sites therefore keeping and retaining Cardiff's green areas. However the Assembly Government Planning Inspectors disagree instead believing that due to Cardiff's need for housing for the law and middle income families who cannot find affordable homes, previous untouched greenfield sites are the only viable option.The developers PMG, part of the St Ederyns Land Consortium, see the eco village as something which will be in Cardiff for generations. If the development does go ahead then it will stretch from junction 30 of the M4 to the edge of the village of Llanederyn. Due to the severe shortage of homes in Cardiff, the development does serve its purpose and links in with the idea of more eco-friendly housing for the city. It also has the benefit of having excellent transport links.
