Metal and concrete corrugated roofs are a ubiquitous feature on homes and shelters worldwide due to their low-cost, but they're really not very good at their job. Both are poor insulators, notoriously prone to leaks and can contain dangerous substances like asbestos ... plus they're not easy to sleep under during a monsoonal downpour. Indian startup ReMaterials reckons it has a better solution with its sustainable, modular roofing system called ModRoof.
A team from the University of California, Los Angeles (UCLA) has designed a shelter that it says can tackle LA's housing crisis in an environmentally-friendly manner. The Backyard BI(h)OME is affordable, low impact and recyclable. What's more, it can be easily constructed in people's back gardens.
Efforts to design a safe and affordable home for the world's poorest and most vulnerable people have resulted in some impressive architectural innovation, including the Bamboo Micro House, S House, and Ikea's Better Shelter. The recently-built Temporary Shelter in Nepal is aimed at offering displaced Nepalese a basic but flexible shelter that can be built by a group of unskilled workers within three days.

Cambodia have collaborated on a project to create affordable housing for
low-income Cambodians. The result, dubbed Framework House, is a
sustainable home that is built primarily from bamboo and wood, and it
costs just US$2,500 to build.
Are our houses over-engineered? They're certainly expensive, thanks in part to the building materials and labor required to construct them. Maison D, by Fouquet Architecture Urbanisme, makes an interesting argument for using budget building materials to produce a stripped-down family house at a relatively affordable price.
