If there's a vacant block without a building on it, people notice valuable real estate and it doesn't stand vacant for long. But there's plenty of prime real estate sitting vacant out there and the owners in most cases are completely unaware of it: it's called the free space on the roof of many city buildings and there's an industry fast growing up to cater for it. The Aisslinger -designed and built Loftcube is a 39 (or 55) square metre penthouse designed to be helicoptered to the location of your choice, as long as it's on a rooftop. Once it is airlifted into place, it can be fully functional inside 2-4 days according to the architects.
