I getting ready to build my wife a built in buffet, and would like some suggestions. The unit will sit between walls that are relatively plum. The overall measurement is just under 8 ft. long, and it will be at counter height. I have done quite a few kitchen cabinet jobs that are similar to this, but there were no problems, as I could make the cabinets in different sections and install them that way, without destroying the already finished side walls. But, my wife wants this as one unit, built more like a piece of furniture, than a cabinet (no toe kick, etc), with a finished front lower trim/base. What is the best way to tackle this without destroying the walls trying to get it in? I don't really want to make it 1/4" short, then trim it out on the sides if I can help it, nor do I want to install the face frame after the cabinet is installed, due to drawers, etc., but at this juncture, I am all ears. And of course, one of the walls is just app. 3 inches deeper than the buffet will be, and the drywallers put on a lot of mud on the corner bead, making the corner measurement less. Thanks for any suggestions.
