UPGRADE

According to H&P Architects, Re-ainbow is designed to withstand heavy storms. It was part-built using recycled and unwanted materials which include scaffolding pipes, sheet metal, brick and bathroom ware. Costs were also kept down by tasking local volunteers with some of the manual labor required.

The firm added some sensible sustainable tech too. A solar panel measuring 1.1 x 0.5 m (3.6 x 1.6 ft) produces electricity and there's also a solar hot water system. A 500 l (132 US gallon) rainwater collection tank is also integrated into the roof, and the building's overall design aims to maximize natural ventilation and lighting.

Re-ainbow was completed this year.
