Work has begun on the next phase of the £2bn Plasdwr residential scheme on the outskirts of Cardiff, a joint venture between housebuilder Edenstone Homes and housing association Codi Group. The new phase, named Porth yr Awen, is a £55m development comprising 184 new homes, contributing to the overall Plasdwr development that aims to deliver 7,000 homes in the west of the city.
Details of the Porth yr Awen Development
The 900-acre Plasdwr site borders Radyr, Danescourt, Fairwater, Penrebane, and St Fagans. Porth yr Awen will include 127 open-market properties and 57 affordable homes, offering a mix of one, two, three, and four-bedroom properties. The affordable housing will include intermediate rental and low-cost homeownership options.
First homes are expected to go on the market in early 2027, with the first residents moving in later the same year.
Infrastructure and Construction Timeline
Edenstone operations director Chris Edge said: “The initial phase of works will see the construction of a spine road into Porth yr Awen, creating access for the infrastructure works that will prepare this development and phases beyond for new homes. Once this access route is created, work will commence on the homes along the tree-lined avenue.”
Simon Lewis, development manager at Codi, said: “It’s exciting to reach this stage of the project, with work soon due to begin at Porth yr Awen. Every new development like this helps us provide more affordable homes for people who need them, while creating places where communities can grow and thrive. Working alongside Edenstone, we’re looking forward to bringing Porth yr Awen to life and creating a well-designed mixed-tenure neighbourhood that people will be proud to call home.”
Plasdwr Master Plan and Community Facilities
According to the Plasdwr development website, the scheme will bring quality facilities over the next generation, including one secondary and four primary schools, a district centre with shops, bars, and restaurants, parks, playing fields, allotments, and healthcare services. Construction of the first primary school is already under way.
Planning permission for the first 630 homes was granted in 2016, with outline permission for the remaining 7,000 homes approved in 2017. Individual phases have been approved intermittently since then.
