A team of volunteers, professionals and entrepreneurs has build an eco-friendly structure - the House of Plenty - out of materials that are not in use right now. The project is irrefutable proof that sustainable collaboration is a more powerful resource than money. The House of Plenty is build in Nijmegen near the River Waal. As part of an effort to create more space for the river, a trench is being dug adjacent to the Waal, which will result in the formation of an ‘island’. The land is being provided free of charge by the local council, which is planning to use the house to accommodate foreign guests there. The House of Plenty will be built entirely out of common left over materials and refuse (old paving tiles, wooden pallets, nappies and door frames) sourced from the street or donated by individuals or corporations who would otherwise consign their unwanted items to landfill or stock. In addition, by utilising innovative technology, the structure will also be self-sufficient. Solar panels are part and parcel of this experimental, eco-friendly building. Not only is the house composed of discarded materials but, perhaps more importantly, it is being built by a social network of volunteers sharing their knowledge and skills. SOCIAL NETWORK This social network is at the very core of the project and proves that it is not money, but the concerted action of people and resources, that is capable of creating something of value. The house will become a place where people can meet to exchange thoughts and share expertise; a place to grow social value, where social and sustainable ideas take pride of place. In turn, this will facilitate a gigantic social network that will disseminate its time, energy, experience and expertise for nothing. It is a sustainable hub welcoming everyone who wants to create new value for society, where knowledge and help can be given to all who need it.
