Building cabinets, with one side of plywood, other side open to wall.
I have a long skinny living room and I want to build wall to wall cabinets on one end. You would only see the fronts on the cabinet structure, not the sides. For the base units, I am considering leaving one side open to the wall. This would mean I'd build one side and a top, then buy the door which comes with a face frame and build 3 out of the 5 sides. The rear and the wall side I would not build out with wood. I would simply attach strips of wood to the wall, and attach the front face frame and the top to those strips. I hope this makes sense. I have attached some images if it doesn't.
Is this a bad idea? I can have the cabinets made for me for maybe a little extra cost, but if I do it this way, I'll gain another two inches inside which in my small space, is a lot. Also, if I order from the cabinet maker, the lead time is like two months, and I want to get started right away. What do you think?
