Alongside colleagues from our associate network, we undertook an innovative feasibility study exploring spaces beneath the M4 motorway in Neathg Port Talbot. The project examined how these challenging urban environments could be transformed through a modular approach to vertical greening and multi-functional public spaces.
Our concept centered on a flexible system of adaptable interventions, including hexagonal modular units designed by associate Will Sandy FLI, that could be configured in various arrangements to create vertical gardens, seating areas, and community spaces. Temporary installations encouraged the client to adopt an incremental, evolutionary approach to introducing permanent solutions, working with the community through practical learning and evidence gathering.
In conjunction we provided the client with a comprehensive engagement strategy involving co-design principles with local stakeholders to foster ongoing stewardship. Our methodology provided a scalable toolkit applicable to other similar sites along the M4 corridor and beyond, while our modular approach enabled a phased implementation path that reduced capital expenditure risks.
The study demonstrated how even challenging urban infrastructure spaces could become valuable community assets through adaptable, nature-based design that enhances biodiversity, improves air quality, and creates meaningful connections between previously divided neighbourhoods.
