Construction on a new multi-use building in Des Moines, Iowa, was completed in October 2014 after 13 months of work. Seth Lamb was sitting in his office next to the site every working day as construction continued, and he took a picture each time. This video shows a timelapse of the construction taking place, allowing viewers to enjoy the sight of progress without being distracted by the sound of the equipment.

The building is intended to house retail units, apartments and office space. Credit: YouTube/Seth Lamb
