Within Allanton's main street still stand a pair of splay-fronted lodges (Lydd Cottage and Westside Cottage), defining the entrance to the former Blackadder House, a magnificent classical house built in Palladian style around an earlier tower house.
The two historic lodges, Lydd Cottage and Westside Cottage, continue to stand at the entrance of Allanton's main street, marking the boundary between the old Blackadder House, a grand Palladian-style mansion that exemplifies classical architecture, and its surrounding landscape.
