Monster model measures 11.22" x 6.27" x 13.8" tall (285mm x 159mm x 351mm). Basic assembly is simple, the model consists of two sides, a front and a back and 44 balcony front pieces (and a few spares). Gluing the little balcony fronts on will take a little time but we have engraved the front of the hotel with lines that show you exactly where they belong.
