It's funny how you have certain expectations for how something will be built, only to discover nothing happens as you expect it! At this point in my barn building land, we have an absolutely beautiful concrete slab layout that looks strikingly similar to the architectural designs layout of my barn plans ... with a 3-D rendering of a wash stall in the middle! Not what I expected. Definitely thought walls and roof before floor. But even without walls, or a roof, I have to say it was incredibly exciting to walk sort-of-in (or maybe on) my barn this weekend!!
