19th Century LabourerÂ’s cottages in Wicklow.

Not sure if this is the right forum for this but here goes. I’m looking for some information on the 2 up / 2 down Labourer’s cottages built all over Wicklow and Wexford in the late 19th (and maybe early 20th) century. My folks used to own an example of such a property years ago and while waking along the Murroughs in Wicklow recently, I came across a derelict example beside the railway line. Would anyone know a website or link where I could investigate further? Many thanks!
