Talk about living on the edge! Danish firm JDS Architects has designed one incredibly cool rooftop playground in a densely populated area of Copenhagen.
Located on top of three penthouses, the shock absorbing surface (aka the grass hill) is the perfect place for daredevil kids and their worried parents to run rampant. For quieter times, they can marvel at the cityscape on the viewing platform or relax around the outdoor barbecue.
A little freaky, don't you think? Let's look on the bright side. Although that low fence must be a nightmare for parents, children who come out unscathed from that death defying experience may grow up to become even more adventurous and confident than the average person!
