Here is the building instructions for the house model of the LEGO 320-1 Basic Building Set released in 1985.

My son plays with this very old set. And I realized there was no building instruction available online. So I examined the box photo very closely to create my own interpretation. My plans were on paper at first. And I enjoyed my day off to produce a cleaner pdf version.
Here is the source file 320-1-house.ldr. You can open it with LeoCAD which is a nice tool to create LEGO models and especially instruction set. Since the pdf export did not contains the brick list per step, I exported a single HTML file that I “printed” as a pdf file with Firefox.
