To use the remarkable topography of the existing site to deliver a new sustainable community where people have access to everyday facilities in order to live, work, learn and relax. Currently being developed by landowner St. Modwen, this community will help contribute to the wider regeneration of a large part of South Wales over the next 20-25 years through the development of:

  • 4,000 homes
  • Secondary and Primary schools
  • District centre with community facilities
  • Green open spaces, play spaces and sports facilities
  • 500,000 square feet of employment space

As part of the masterplan, St. Modwen will also agree the Town Code, a series of rules, illustrations and guidelines which ensure that the design vision for the new community of Coed Darcy will be realised.


Coed Darcy is uniquely set near the protected wetlands of Crymlyn Bog, which is recognised as an area of conservation and of ecological importance. The western end of the site will remain largely undeveloped to protect the natural biodiversity and ecology of Coed Darcy as well as its breathtaking views and remarkable landscapes.

St. Modwen is also carrying out a programme of extensive ecological works to protect sensitive species, which will include the provision of additional habitats to encourage a bio-diverse sustainable environment. The overall aim is to create a diverse range of landscape and ecological habitats throughout the scheme, each with its own specific character and function.


Coed Darcy will provide 4,000 high quality homes to around 10,000 residents, offering a wide range of types, sizes and tenures.

Coed Darcy's three neighbourhoods will be linked by village greens, play areas and winding lanes to give the community a village feel. Amenities such as shops, schools and parks will be built within walking distance from the homes to create the perfect community.

The residential community at Coed Darcy is taking shape. The first phase of housing at Heritage Gate, built by Atlantic Properties in 2010, is now fully occupied.

Amy Forbes and Andrew Kuhne were among the first residents at Heritage Gate. Amy said: "We looked at a couple of other estates, but we felt there was nothing special to them. We instantly just loved the architecture and the fact natural Welsh materials had been used in the construction. It gives a completely different feel."

Reflecting Coed Darcy's origins (Darcy's Woodland), the community will be populated with a vast array of local plants and trees to help reflect the wider natural environment.

There will also be play areas close to homes for toddlers and young children. Coed Darcy will have Neighbourhood Equipped Areas for Play (NEAPS) providing suitable leisure space for older children and Local Equipped Areas for Play (LEAPS) which will provide play space for children between 4 to 8 years old.

These play areas where possible, will be overlooked by adjoining properties and well maintained, with play equipment of the highest standard.

A comprehensive network of cycle routes and footpaths will thread through and around the scheme. The routes will have good connections to the site’s leisure facilities, schools and business area promoting alternatives to the car and a more sustainable form of transport.

Coed Darcy will be shaped by the community's home and business owners, who will become members of the Coed Darcy Community Management Company.

The Community Management Company will allow residents and business owners to help shape the physical development i.e. the maintenance of public and community areas, and the community’s design including buildings, streets and community facilities.

The aim will be to create a strong sense of community at Coed Darcy.

Set near a dramatic coastline, and within easy access to Cardiff and Swansea, Coed Darcy will be a great location for exploring and living in south Wales.

St. Modwen is working with global environmental consultants and experts, Atkins, to clean up and redevelop the former BP Llandarcy Oil Refinery site in a safe and sustainable way. The entire process is monitored and overseen by Environment Agency Wales and Neath Port Talbot County Borough Council.

The company employs the sustainable and technically advanced remediation methods including biodegradation techniques whereby micro-organisms are used to clean up the soil.

Key Remediation Milestones

  • 100km of pipeline and cable removed.
  • 200,000 tonnes of concrete has been recovered, crushed and will remain on site to provide recycled hard core for the buildings.
  • 5,000 tonnes of steel recovered and the majority recycled on site.
  • Enough oil to fill 9,000 tanks of fuel in the average family car (600,000 litres) has been recovered and recycled through an extraction process.
  • 95% of material extracted from the site has been reused during the construction process.
  • A groundwater drainage strategy has been developed to meet the needs of the Crymlyn bog (a site of natural and international wildlife importance).
  • Biodiversity of the site has been enhanced and a waste strategy developed.
  • The construction materials for buildings are sourced locally.
