I allowed for an opening at the back of the platform to plug in the washer and dryer and to connect the dryer vent. I nailed some scrap 2×4 material flat, at the top of each of the small walls for corner sheetrock backing.
used some finishing nails around the top edges of the frame where the cross support beams were and along the sides and front to provide a tight fit and seal for the glue to hold it all together.
