On the website is a sideboard, beautifully made.
When we had our kitchen cabinets made, the builder could make the doors/drawers so when they closed they overlayed the cabinet (about 1 1/2 inch of the frame showed between adjacent doors/drawers), or he made them so they were inset, like the photo.
He told us, in older homes like ours that are prone to settling, he can make the doors and drawers so that they overlay, but are only 1/2 inch from the door/drawer next to them. Craftsman kitchens were basically inset and this was a way to kind of get the look, and settling issues would not mean the door/drawer didn't work.
Our house settles , prevented by the railroad rail holding it up in the basement, mostly.
As a first item, maybe the inset doors are not the best idea, imo.
