Garthland House Staircase on the outskirts of Lochwinnoch, was one of Renfrewshire's most majestic mansions. The greyish-pink Tudor-style architecture of the two-storey building was enhanced by a pillared porch, elegant stairway, ivy-clad walls, pedimented portico, soaring chimneys, sloping roof and exquisitely-carved dormer and bay windows. Built in 1796
