Create a 3D model of a Roman infantry barracks building. The structure should be made of stone and wood, with a large rectangular shape and a thatched or tiled roof. Include multiple columns and arches at the entrance, with walls featuring Roman brickwork. The interior should have open spaces with stone floors, wooden bunks, and weapons racks for storing swords and shields. Design the building to have a functional, military feel, suitable for training and housing Roman infantry soldiers.
