This is a great little structure with decent detailing at a excellent price point.
The kit was easy to assemble though the roof and its channel system was used, without glue, to help keep the walls square as the glue dried holding them to the floor. A bottom floor was added for better stability and to minimize light leakage since all layout structures have internal lighting. As with most all N scale kits, care must be taken when separating parts from the sprue. A sharp knife with both bottom and top support is helpful to prevent breakage during separation. The assembly and how the pieces fit are somewhat like the Osborn Snack Shack (base and front porch) and Osborne MOW shed (roof channel system-its method of attachment).
It would be great if additional pictures were provided by the company. Had to contact Osborn prior to purchase and inquire about whether the back or opposite side had windows or other details since internal lighting needs at least 1 window to be useful and would have purchased something else if no window existed. The tool detail adds a neat touch and the metal parts were painted a dark gray.
All in all, an outstanding value compared to offerings of similar products in the category.
