- The House at the Edge is in the South Downs National Park, a beautiful dark skies area in the South of England. The food forest garden includes over 60 fruit and nut trees, edible and medicinal herbs, berries, and vegetables and cultivated fungi. The sauna is heated by wood from our woods and chopped by Emma and her coppicing companions. Ten minutes’ walk down the lane and across the field is 11 acres of ancient woodland lovingly managed by Emma's community of coppicers, craftsmen, women and tree lovers.
