Even if the mechanism of the cuckoo clock remained basically the same, there were a lot of changes in the designs of the case. The variety in the designs of the birdhouse came about since the manufacturers wanted to satisfy different tastes and therefore attract new customers. Some of the more common designs include that of one or two men drinker beer, or a simple design with birds and leaves on the front. A new design is one with Swarovski crystals adorning the case.

The designs are usually for wall clocks and desk clocks. The sound does not always come from cuckoos. Modern designs have done away with the bird; but have retained sounds that ring or chime. But the most impressive one is the grandfather cuckoo clock. It makes a grand statement with its resonating sound that can be heard all over the house. They also make a grand presence with the imposing wood cabinetry.
