low-poly building 3d model

Create a large stylized low-poly 3D building where players will eventually complete challenges. It should look more important and slightly mysterious than normal buildings, but still be family-friendly and suitable for a Roblox game. Make a large entrance, thick walls, several windows and a strong recognizable silhouette. Use simple chunky geometry and clean surfaces. Leave the interior mostly empty because gameplay objects will be added later. No characters, no text, no background environment.
