Is this the same farm (site) as the existing Newbridge farm just off the A76 and across the road from Lochside Industrial Estates? If so there does seem to be an older house at the western corner of the site. It’s hidden by a hedge on street view, but the chimney stack looks old. When was the building that interests you demolished?
Added: looking at the layout of this farm on the 1900 6 inch OS map there isn’t an obvious candidate for the building I describe above, but the road alignment looks a little different too, so it isn’t clear how easy it is to compare.
