Kassel grandfather clocks vary in their designs according to their make. Often they are custom built catering to the customer’s whims and fancies. Some of the extra accompaniments in these clocks are curio cabinets at the bottom of the clocks. Some clocks have chimes built in them so that the owner can enjoy an extra song for the day. The only drawback of the Kassel grandfather clock is size. Almost all of them are of an average size of 6 feet by 6 feet. They stand an extra 4 inches off the ground. If you are looking for a smaller sized clock then you would have to move onto another brand.
