The is the first prototype of the the Cube Project called QB1 and it was unveiled recently in St. Andrew’s Square in Edinburgh in Scotland. QB1 is a literal cube inside, three meters wide by three meters long by three meters high — roughly 97 square feet, and it’s spacious enough to house a lounge, table, two chairs, a double bed, a full-size shower, a kitchen, a washing machine, and a composting toilet.
The carbon-neutral cube is designed to generate more energy than it uses over the course of one year. A Mitsubishi 1.48 kW rooftop solar system, upon registration with the UK’s feed-in-tariff program, would send about $1,600 cash to the owner from surplus energy over the year.
Other green aspects of QB1 include LED lighting, an Ecodan air-source heat pump, heat recovery ventilator, cork flooring, a Samsung Ecobubble washing machine, and a low-energy LED television.
In addition, the tiny home has a Kingspan Pottan timber frame and insulation, FSC-certified English Sweet Chestnut cladding, FSC-certified birch plywood interior panels, and Nordan NTech triple-glazed windows.
QB1 is simple to use — all it needs is a grid connection and cold water. A composting system separates liquid waste for the gray water processing and solid waste for composting. The home was designed and developed by Dr. Mike Page as a project of the University of Hertfordshire. It was built with sponsor donations, but that could probably be replicated for ~$80,000, according to The Engineer.
