A sound book that makes boys' hearts race. Six wonderful construction sounds are showcased here. The rumble of truck engines, the scraping of the excavator's bucket, the clanging of steel, hammering, buzzing drills... Done. The house is finished. Ring the doorbell. In addition to the impressive original sounds, you can also discover plenty with your eyes, just like in every volume of the Hör mal series. This saves hours of standing around at construction site fences.
