After earthquake in 2001, Hunnarshala researched few techniques for fast redevelopment of the area in Kutch, Gujarat. They first initiated the use of space frame systems for semi-temporary structures in rehabilitation due to its fast construction & cost effectiveness. Later after executing this roof technique in several projects they saw potential in this technique as a permanent roof understructure. They researched on shape and design to make use of these roof understructure techniques in routine construction practices. During this process Hunnarshala realized the complexity of existing method of joints construction used for such structures. To make this process fast and more reliable they modified the joints / junctions which reduced the installation time. They educated the team about the techniques and mentored them to use the same in different projects and encouraged them to start a company which solely provides this technique of roof understructures.
