daruma-otoshi is a japanese building demolition technique that takes a building down one floor at a time on ground level. the process uses mechanical supports to replace the buildings structural supports and lowers the building down as it is demolished. from afar it would look like the building was shrinking over time. the company that created this method claims it helps to reduce the environmental impact, making sorting for recyling much easier and also lowers the amount of potentially harmful airborne debris. pretty genius if you ask me. there’s an awesome time-lapse video here
