Achieving a biodiversity net gain can be challenging on greenfield sites such as The Uplands in Nailsea where we are delivering 54 new mixed-tenure Passivhaus homes on a former playing field as an extension to a suburban neighbourhood for North Somerset Council. A greater challenge was a bat corridor following an ancient Holloway to the south, requiring care to avoid light spill. A swathe of inaccessible land along the Holloway creates a re-wilding strip. This landscape-led approach permeates the site with a network of habitats linking the surrounding woodland and hedgerows. Native hedgerows take the place of garden fences. 56% of the site is earmarked for landscape and biodiversity, delivering a biodiversity net gain and habitat improvement for target species.
