The current model of cities development, considering the wild consumption of not renewable resources, has shown impracticable due the sustainability point of view. Fact which is really concerned a lot of preoccupation in many sectors of human society. In the world-wide scenery, mainly at civil construction sector, it is growing a big demand for the use of new and alternative materials and techniques that may not harm the world environment. Due this situation, in the academic field that is considered an excellent research environment, it is the right place to new materials and techniques born in order to supply the demands considering the sustainable development. In this context, the LILD (Research Living Design Laboratory) has been studying last 20 years the applications of clean and low environmental impact technologies, answering the demands of building the design and architecture of real objects. This work presents the result of the developing process of an object named CATENARY DOME, applying the project methodology of LILD. The experiments have been developed of processual models that determined the parameters and point directives to be followed in the project, having in mind always the application and construction of an object in real scale, that incorporate many different knowledge areas.
