I remember when a simple floating building was the avant guard of design. Now engineers are pushing the limits with even more outrageous designs. Can you imagine living in a high-rise apartment building where the 360 degree views are of fish and saltwater? Although still just a concept, this upside-down, underwater eco-skyscraper (say that five times fast!) could be the future of building, especially if sea levels rise and we are forced to spend our lives living on floating islands. Designed by Victoria BC-based firm Zigaloo the Gyre is a floating eco development meant to be both a research station as well as an off shore resort complete with shops, restaurants, gardens and recreation.
