The Ralston estates were eventually carved up and sold as farmland in the late 19th century. The ruins of Ralston Mansion were demolished in the 1930s, however part of the original stonework forms an annex to the club house at Ralston Golf Club. The East and West Lodges on the Glasgow Road were the original gate houses to the estates. In the early 19th century, the development of the textile industry in Renfrewshire resulted in the increase in road traffic across the county. The main road running through the Ralston estates was nothing more than a narrow dirt track. The original road ran from Paisley, through the then-village of Williamsburgh and across the tops of the Byres, Barshaw and Honeybog hills. When a programme of long distance road construction was introduced, a new road was built, snaking through the low-lying ground at the foot of the hills. The original track later fell into disuse and the new route became what is now the Glasgow Road. Villas began to appear along Glasgow Road in the late 19th century, mostly in what is now the Oldhall district near Barshaw Park. A village-proper was established in the valley between the hills of Bathgo and Honeybog in the early 1930s as post-war residential development increased. Developers planned Ralston as a leafy haven for wealthy Paisley textile merchants, wishing to raise their families in a more rural setting beyond the burgh’s boundaries.
