We built Speckled Wood entirely from timber grown on the National Trust’s Blackdown estate near Haslemere, Surrey. Named after a butterfly that frequents the local woods, the building is a roundwood frame of sweet chestnut, with larch wall plates and ridge pole. The chestnut shakes were constructed by volunteers on national trust working holidays. The building is used by long term volunteers/apprentices who then go on to work on other national trust land. By design, the residents should embody the essence of sustainability by living in speckled wood.
