This chapter presents related studies which have direct bearing on our research. It also presents different kinds of portable or folding houses and its applicability in our society. This also discusses about low cost houses which is suitable for low income families. Low cost houses are intended for fast increasing population country that prone from illegal settlers, who lived and stayed in urban places in order to work and to do other activities for survival.
With the high cost of building materials, the designer is task to design a residential house with a limited budget to provide his client a decent structure with basic comforts of a house although the amount for the building is limited and low. It is therefore necessary to find ways to satisfy the needs of the client while the laws of design and structure are also observed. (Suralta, Myron A. , 1999) Because of that, our group came up with a design of folding houses which is preferably for the low- income families and in flood and typhoon prone areas in Cebu city.
A Chinese researcher Ming Tang (2008) developed a folding bamboo house. These are origami inspired shelters which are temporary shelters for the earthquake victims in china. The central feature of this project is the development of a temporary shelter for the homeless people, a kinetic structure that exhibits characteristics of umbrella and folded fans. It is a self-reconstructive structure for instant installations, which, according to the changing internal requirements and site topography.
These light weight folding houses can be pre- assembled, folded into small parts, and loaded into a truck for transportation (Ming Tang, 2008). Another project is an Accordion- like recover shelter. This project is sturdy, inexpensive and surprisingly of great look. It is made from food- grade recyclable polypropylene that is folded and stacked for easy transport and is easily assembled by only one person. It can be tied down to protect against the wind and simply zip- tied to additional units to form a larger structure as needed.
These are designed for disaster relief, the recover shelter can house a family of four for a month. A wonderful giant accordion house to for those who are disaster ridden or a super-hip tent for the super-hip green hipster-camper (Matthew Malone, 2008). Because of disaster, Rafael Smith (2011) developed an emergency shelter that looks more like high class camping or a candidate for the ever-growing tiny house movement or folding houses.
Uber shelter is an amazing concept for a portable housing unit that would help people in meeting their immediate shelter requirements created by disastrous events. This shelter can be very quickly transported and reassembled with just few necessary tools and offer victims with individual living space. The best thing about Uber shelter is that it is made from recyclable and reusable materials. Around two to three personal rooms can be created in this shelter. He believed that these types of concepts are very useful for unpredictable disasters (Rafael Smith, 2011).
This project is a transforming house turn inside out for summer. The dynamic, which, taking cues from a mathematical problem posed at the turn of the 20th century, can fold itself into eight different configurations. The house design’s adaptability makes it deadly suited to extreme climates. The design of this structure is based in the haberdasher’s puzzle, discovered by English mathematician Henry Dudeney, which allows an equilateral triangle cut into four parts to be folded into a square while all pieces remain contact with at least one other.
The idea of this puzzle is being applied into the design of the house that changes shape, but it’s apparently well poised to adopt the changing of the seasons over the course of a year. During summer, the house effectively turning itself inside out and upping the exposed surface area. It can also be rotated to constantly exposed to sunlight, while the house generates energy through a solar panels (James Holloway, 2012) Another type of project is a portable bubble house pops in a snap.
