Site Description

Coopers Green in Hatfield is one of Hertfordshire’s most compelling large‑scale development opportunities, offering investors a rare combination of scale, planning certainty, and long‑term growth potential. Fully allocated within the Welwyn Hatfield Local Plan and supported by a jointly prepared Supplementary Planning Document, the 247‑acre site provides a clear and reliable roadmap for delivery, significantly de‑risking the planning process for development and funding partners.

The scheme will deliver around 1,750 new homes as part of a major strategic expansion of North West Hatfield. Alongside housing, the plans include new primary and secondary schools, a neighbourhood centre, retail and commercial space, and extensive green infrastructure designed to support a resilient, mixed-use community for the long term. Phase 1 already has a development partner appointed for 350 homes, and partners are now being sought for the next three phases, offering substantial opportunities for early and sustained investment.

With an anticipated Gross Development Value of approximately £500 million, Coopers Green offers significant potential across residential, commercial, leisure, and innovation-aligned workspace. Its location provides fast rail links to London, strong regional connectivity, and enduring demand from both residents and employers.

The project is being brought forward by Gascoyne Estates, a long-established landowner with more than 400 years of stewardship and a proven commitment to sustainable development. Working in partnership with Welwyn Hatfield Borough Council, Hertfordshire County Council, and supported strategically by Hertfordshire Futures, the scheme offers a unique opportunity to shape a high-quality new community in a key growth corridor.
