A portable, energy-efficient home that was originally built for a competition may be available on the market soon in Africa. The design was created by team Jua Jamii, a group of 40 former university students from countries including Tanzania, Nigeria and Swaziland. It uses recycled shipping containers and is 100% powered by solar energy. When Jua Jamii started building the house, the plan was simple — to create affordable and energy-efficient housing for middle-income families in Africa. The team expanded from six members to 40 in 2018 to make room for the implementation of all ideas. By gathering shipping materials from a port in Morocco, they were able to lay the foundation for the building. Jua Jamii also focused on equipping the house with a 24-hour power supply.
