A couple of my kitchen improvement projects:
Made the drawer boxes myself with prefinished drawer sides from Richelieu. Slides are Blum undermount, soft closing. Notice that you can't see any hardware on the sides of the drawer.
Also made from prefinished drawer sides. I couldn't use undermount slides here, becasue they are sold in pairs, and I would have needed two right hand side slides. Also soft closing, but I haven't adjusted them enough for the soft closing to work completely yet. Do you know how hard it is to work in a 6" wide cabinet?
Both cabinets were just full height "empty space with one single shelf only at the back. Now I can store about 4x the amount of stuff in each.
