The product arrived timely and very well-packed; and upon inspection, every piece was in excellent condition. While others have complained about pieces not being labeled, we found that the extremely detailed parts listing made sorting everything out a very straightforward process. We opted to stain our greenhouse, and as recommended we did it entirely before assembly. This was easily the most time-consuming part of the project, taking about two weeks in our garage (mostly due to dry time). And for future reference, we used nearly 4 gallons of Cabot Australian Timber Oil - Natural in our application. As an added plus, we found that touching every piece was really helpful in understanding how it all was eventually going to come together. The actual assembly process only took a long weekend to complete. We found the instructions very detailed and thorough. There were a few questions that we asked the OLT group as we went along and they answered quickly and effectively. Make no mistake, you are assembling a small house and not some particle board furniture, so there is some effort and attention to detail required here, but nothing too complicated. Also, I'd highly recommend getting several clamps (we purchased four 12-inch versions at Harbor Freight for only $5 each) to assist along the way and they were lifesavers to really help assure everything was straight and square. The entire process couldn't have gone better and we couldn't be happier. We are more than completely satisfied with the results. Plus being the envy of the neighborhood is an awesome bonus!!!
