I was thinking of doing something similar on my column by the entry door. Instead of having a bank of 5 or 6 dimmer switches on the face of the column, I was thinking of leaving the actual dimmers behind a hinged panel and mounting a single 6-button keypad flush with the face of the column that would control all of the lighting scenes. Would the code police frown on hidden light switches?
Awesome progress by the way. The columns and panels look great.
