  • Classroom Project- Design of a shelter
  • The Objective was to design a simple, portable, low-cost shelter for laborers working on site in Rajasthan, India.

    A study of the working conditions showed:
    a. They walk 4 – 5 km everyday from their village to the jobsite.
    b. They carry their tools and children with them.
    c. Theterrain at thejob site is rough , rocky , with a lot of dry patches and sparse vegetation.
    d. Itgets specially hot in the afternoonswith temperatures hovering between 32ºC– 48ºC.

    It is here that a design opportunity was seen andtherefore , the need to design a portable, collapsible shelter for them wasaddressed.
  • They take shelter under whatever bush or tree they can find, which is rare or highly inadequate.
  • Concept Sketches
  • Explorations with straw
  • Concept Trials
  • Preliminary model using PVC pipes and joints were made to test the concepts
  • Iteration: To use the concept and tessellateit so as to make a modularshelter with multiplemembers that can be added or removed
  • 1:1 scale model using Bamboo , cloth and Nylon Rope, materials that would be easily available in the villages. Theaddition of holes in the main beams give the possibility to further expand thestructure
  • Final ConceptThe inspiration for this concept came from the slide-lock mechanism usedto lock the tables in place in a railway coach, and a blind man's walking stick.
  • A 4:1 scale down model was made out of PVC pipes and nylon rope to check its collapsing ability.
  • Shown here is the 1:1 working prototype.
  • 3 people seated inside comfortably
  • Dimensions in feet
  • Materials used :
    PVC Pipes
    Nylon Rope

    Total area : 88.7 sq ft
    Base area : 27.6 sq ft
    Volume : 63.8 cubic ft
  • Features: Lightweight, Portable, Low Cost, Easy to Install and Uninstall, Materials easily Available, Easy Maintenance, Material Reuse.
