Following recent approval of reserved matters for up to 200 dwellings at Hill Place near East Grinstead, HDA has now produced the landscape, ecology and arboriculture inputs into the construction tender package.

HDA is also working with the council to finalise the proposed Suitable Alternative Natural Greenspace (SANG). The SANG will be a significant new open space on the edge of East Grinstead, providing new public views of the re-opened Grade II listed Imberhorne Viaduct along the Bluebell heritage railway.
