JimBuilt, the depth of the galley kit is 15″, the length is 56.5″ It gets a little trickier with the height. If you look at the galley, it has 5 sections, the distance between the sections are approximately: 9.5″ – 11″ – 14″ – 11″ – 9.5″ the heights across the front of those sections are 12″ on the ends, 16″ across the rest. The back of the 14″ center section is approx. 19″ sloping down to the 16″ in front. Hope that makes some kind of sense. Good luck with the build. Love to see some pictures when you get it done.
