This is a scratch-built high-rise apartment building, or "tower mansion," in N-gauge 1/150 scale. The main materials used are styrene board and plastic sheets. The footprint is 18cm x 18cm, and the height is approximately 60cm. The base plate has holes, and the interior of the building is hollow, allowing for LED wiring. The first floor is an entrance hall, and floors 1 through 4 house a combined commercial facility. The commercial facility, residential area, and rooftop are separated, allowing for smooth construction. Although not strictly necessary for its use, the unique structure provides a decent amount of strength. The high-rise structure, equivalent to approximately 100m in N-gauge scale, is a sight to behold. Thank you.
