Surveys Floorplan/construction schematics Airy Duo Scotland 1931

Hello, I'm interested in finding the floorplan or building schematic for an airy duo non-trad built in Edinburgh 1931. Can anyone help at all? These were/are council properties, four homes in one building. Thanks if anyone can offer advice or provide an architect's drawing. Interested to find out size and spaces between properties including crawl spaces underneath and between adjoining floors.
