Bankes' son, the explorer and adventurer William John Bankes, commissioned his friend Charles Barry to encase the red brick hall in stone, and enlarge his other property Soughton Hall. Barry remodelled Kingston Lacy between 1835 and 1838. The work involved facing the brick with Chilmark stone, adding a tall chimney at each corner, and lowering the ground level on one side to expose the basement level and form a new principal entrance. He planted beech tree avenues along the Blandford Road, of which some survives.
