Plasdŵr will develop over 15 to 20 years and so lots of questions will emerge over time and be added here. If you have a query that is not covered here, please get in touch via our Contact page.

There’s no doubt that traffic congestion is an issue in Cardiff – the city has grown, is growing and has the opportunity to grow further. Transport is fundamental to that growth, and the Council has a transport strategy, which is part of its Local Development Plan (LDP). This is based on prioritising walking, cycling and public transport, so that everyone – including car-users – can get about easily and conveniently, which is how we have planned Plasdŵr from the outset.


Through the section 106 agreement, developers will provide £27.76million to support transport, including improvements to existing infrastructure including originalised junctions and increased bus lanes and services.

Plasdŵr itself has been cleverly planned to enable to walk, cycle and use public transport more easily than their cars, cutting journey times and maximising convenience. So lots of cycling and pedestrian routes are planned as well as high quality bus services, to get  people to work, school and to their leisure activities.

Where Plasdŵr adjoins its neighbouring communities in phases 1 &2, there will be improvements to Llantrisant Road, Heol Isaf and Pentrebane Road to encourage use by pedestrians. On the llantrisant road junctions with Heol Isaf and Clos Parc Radur, buses will be given priorityand an additional buslane provided, and an extension of Pentrebane Road is planned into the new development, plus a widening of Pentrebane Road to accommodate buses.

Plasdŵr will include the introduction of three new super cycleways through the site, connecting to the Taff Trail and the Ely Trail. Generally there will be buses running up to every five minutes, and people will be able to connect between buses, between bus and rail, and bus and bicycle.

Infrastructure and construction works are now underway for the first phase of Plasdŵr . It is anticipated that the first residents will move in by the end 2017.
There will be 15% affordable housing at phase1, which will equate to 7.5% at intermediate rent, with 7.5% at low-cost home ownership.

30% of Redrow’s Cae St Fagans site on the south of Pentrebane road will be affordable housing.

Plans for Plasdŵr include four primary schools and one secondary school, shops, offices, health and leisure centres, pubs and restaurants. The first of the primary schools will be delivered by 2021 as part of the first phase of the development and will provide 480 places.

New health facilities are proposed for the next phase of development.

The development is not built on or near any flood plains.
The lead developer for Plasdŵr, Redrow Homes, is currently operating a Sales Centre from Pugh’s Garden Centre in Radyr. The team there will be able to answer any questions you have relating to sales for the current phase of Plasdŵr.

The Sales Centre is open Monday to Saturday from 9:30am – 5:30pm and on Sundays from 10:30am – 4:30pm and you can reach them by calling 029 2060 0373.

As work on Plasdŵr progresses, a number of different developers will come on board and help create distinct areas of individual character within the community that will feature a variety of styles and designs. Work at a second Redrow site of 290 homes on Pentrebane Road will begin in August 2017. Details of new developers and where they will be building at Plasdŵr will be updated on this website.
The Masterplan for Plasdŵr underpins both the housing need identified in the Council’s Local Development Plan (LDP) and the projected economic and demographic growth of our capital. North west Cardiff is identified in the LDP as a Strategic Site for Development (strategic site c).

The LDP proposes the legal framework for the development and use of land within Cardiff up to 2026. It provides the context for determining local planning applications.

Actually, there isn’t enough brownfield land to meet needs. The Wales Spatial Plan Update 2008 (WSPU) identifies the area around Llantrisant and north west Cardiff as a Strategic Opportunity Area (SOA) suitable for sustainable development.

It states that initiatives for major economic growth in south east Wales should be focussed in a corridor from Cardiff Bay and city centre to Llantrisant and Talbot Green.


Cardiff has an identified housing need to cope with existing demand and continuing and projected demographic and economic growth. It is already widely accepted that we need to develop in north west Cardiff, with the Wales Spatial Plan Update 2008 (WSPU) identifying the area around Llantrisant and north west Cardiff as suitable for sustainable development. It also states that initiatives for major economic growth in south east Wales should be focussed in a corridor from Cardiff Bay and city centre to Llantrisant and Talbot Green.

The masterplan for Plasdŵr received planning in March 2017 and represents an opportunity to enhance Cardiff even further by creating its own garden city – a great place for people to live, work and play. The fact that this entire development can be delivered on land under single ownership is also extremely helpful as it eliminates many of the complex land assembly issues normally associated with a project of this scale.

Plasdŵr will definitely not be an enlarged housing estate: the vision and masterplan fora joined-up, sustainable community, a living, breathing place. To create this, landowner, Plymouth Estates and lead developer, Redrow have looked at the whole area, and how the different parts will fit together and function well. Transport infrastructure and high quality, varied design throughout will also be critical in establishing Plasdŵr both as a place with character and a sustainable community.

So, when we were preparing the proposals, we looked at connections and movements first, as these tend to be the drivers for commerce and growth which, ultimately, establish places. The plan therefore identifies where the main movement corridors will be and builds up a comprehensive hierarchy of routes – footpaths, cycle routes and roads. Taking the topography of the land into account, and the need to knit sensitive areas of landscape into the development, this network forms the foundation stone of Plasdŵr as a sustainable place.

From there, we looked at land use distribution, balancing community, retail, business and housing uses, and developed more detailed design.

Please see the Design and Access Statement in the downloads section for more detail.

The current areas of land being released at Plasdŵr are for residential development.  Future phases of Plasdŵr will contain commercial and retail development and these will be brought to the market in due course.
