It is still on the map - I used
www.streetmap.org.uk - but as you say there aren't any houses there now.
The 1892-1905 six-inch map shows the road branching at Brucefield and running west-south-west past the farm of Burnhouse, with no other houses along it.
The 1945-48 and 1955-61 one-inch maps show a row of houses east of Burnhouse, and some industrial development further west - some sort of mine.
The 1973 1:50,000 map shows Burnhouse but the row of houses is not shown. So the houses must have been built before 1924 and demolished between 1961 and 1973.
Given those dates, and the fact that there was a mine further along the road, I would guess that No 13 was one of a row of early 20th century miners' cottages.
