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.
