We have two great dogs that use a standard dog door. It is incredibly convenient, but I never liked the look of the door. I decided to upscale it with a custom-made door frame and a raised panel door. Everything was built out of pine. I bought stock molding for the header and routed the fluted columns and plinth blocks. The door was made with a 3-piece raised panel, rail, and stile bit set on my router table. The knob is a pair of brass kitchen cabinet knobs, and the hinges are just some small butt hinges. The original plastic flap door is still in use, but this makes it look a lot better. Unfortunately, I didn't take pictures along the way, but you can see the before, after, and in-use shots. Hopefully it is enough for others to copy.
