I went with 1 x 2 and 1 x 3s for the furring strips.Started with self-tapping screws but eventually transitioned to pre-drilling then using sheet metal screws. The furring strips are set every 24 inches. The 1 x 3 was used at the seams where the plywood would meet.

The 1 x 3 was used at the seams where the plywood would meet.

Here is a picture of all the materials for the subfloor and walls. I insulated and installed one section of the subfloor. Then moved all the materials onto that spot.

The Ryobi inverter generator powered the entire tiny house build. #Ryobination

Here is the 1″ foam board insulation installed with foil tape used to seal all seams

OSB subfloor installed. The same predrilling and sheet metal screws worked here also.

I used 3/4″ OSB for the subflooring that I found at home depot. There may have been better options.
