Q-vention can build a self-sufficient city, complete with infrastructure, to house all local people. The city will have schools, churches, shops, industry, sport complexes, playgrounds, hospitals, fire stations and a large public park. All neighbourhoods will have their own service district containing shops and other services. Examples

Unique water supply system.

When its a climate of 9 months drought and 3 months rain season. In those 3 months there is a staggering 3 meters of rainfall. This enormous amount of water is ingeniously captured through a complex system of bridges and canals as well as through the gardens and park-like layout of the neighbourhoods. The water is stored in a basin, purified in the water purification plant and supplied back to the city to provide it with water in the dry season.

Local involvement.

Q-vention builds a prefab factory in the proximity of the city to-be. All construction materials are supplied by local suppliers. Local contractors are trained and supported by Q-vention experts to build with the Q-vention Blocks system and to follow the urban- and architectural plans.
