Initially I was not sure if I was going to add doors as I thought the sides, back and lid would keep it sufficiently covered from the sun and intense wind/rain - so I did not measure & cut those at the beginning. While you can certainly use a better type of wood, especially if it was something big enough to walk inside, I just decided to use the simple & more affordable OSB plywood for this -project.
Using the circular saw and the handy sawhorses (
see previous article to make these), I measured out the dimensions for the laundry house and cut the pieces, making them big enough to leave some extra room in the front and on both sides - for laundry soap etc. storage. Then I cut four 2x4's to the same height of sides and attached the back and sides together with my impact drill and added two at the front that would be needed once I decided on the importance of doors.
