H2Office earns its place in the cool book simply because this baby floats. The 9 meter long office can hold 2 desks, a fold-out bed, lounge, kitchenette, and there’s even a sun deck at the top to make this office even more desirable. It feeds off a 240V power supply from the shore, which is a huge shortcoming. You could get some of the energy from wind and solar power, but that’s not all that interesting. The office has a number of customization options to suit your needs. Like all good things, this one is expensive as hell. Costs $90,000.
