This isometric view shows a room with a hexagonal interior, three windows and one door. The outside of the room is a cube cut by some spheres and columns, and the inside is a hexagon. The place where the hexagon and the sphere are cut forms a curved window, which can provide light for the room. A cuboid passes through the hexagon and cube, so that the outside can provide ventilation without contact with the inside. A leaf shaped door is opened on the surface of the cylinder cut hexagon.
