So what is the issue with this type of construction? At the top of the list is how to make and install it. A 101" wide series of cabinets made in the shop and then moved to a kitchen would be challenging. It is more modular to have a series of separate boxes and then screw them together as they are installed. Often these cabinets are frameless, otherwise the face frame will become very wide.
For this project, I plan to use recycled oak flooring. I started using flooring on a previous project. My reason is purely economic. Solid wood is expensive but reclaimed oak is $1.25 a square foot. A piece of flooring is shown on the left in this picture. After removing any nails or staples, I rip off the tongue on one side and the groove on the other. Since the flooring bottom is recessed in areas, I rip the bottom too for a flat surface. The final board is a little over 5/8" thick.Sketchup has allow me to view the size proportions of the rails, stiles, drawers and cabinet walls without having to make a prototype or just live with the results. For this project I have a 1 ¼" wide wall. I use two flooring boards glued back-to-back to achieve this width. My tablesaw is the clamping surface and any warp that the flooring had is eliminated.
This shows the face frame with a drawer and door opening made from cabinet-grade plywood which I had applied quarter-sawn white oak veneer. I will use veneer edging to cover the exposed inside edges. The piece of wood in the center shows a sample of the wood flooring. To cover the glue seam, I glued veneer and then rounded over the edges.
