The main goal of this Master thesis is to design and construct a grid shell structure, which is subsequently realized as an experimental structure on a prominent place in front of main entrance to Faculty of Civil Engineering (FCE), Czech Technical University (CTU) in Prague, Czech Republic. There is a need for an elegant long-lasting structure which will at least partially cover an existing pool. This should make the place suitable for various events and also a friendly, pleasant, relaxing and free time space. By thinking about how such structure should look like and what materials and structure types are suitable, there were many kinds of lightweight structures considered. The direction which the CTU is focusing on nowadays is to experiment new and original possibilities of building structures, create sustainable architecture and consult with other specialized departments on FCE CTU on higher level during the design process. Single layer tensioned membrane structures are at present very popular, however, finances could be an obstacle. Tensioned membrane structures would require cable anchoring, which is not suitable to anchor around the pool where walkways are located. For these reasons, the most logical solution is to create a grid shell structure combining with a single layer membrane that would fulfil all aspects of elegant remarkable lightweight structure using some original details and workflow advancements. The goal of this project is to design a structure which will then be built in spring 2016 in cooperation with other departments and students from FCE CTU Prague. This grid shell project should demonstrate another possibility to build and think about unconventional structures and provoke a deeper interest in these unique structures. In the Czech Republic such systems have not been applied in an adequate scale as a permanent structure yet. The goal of this Master thesis was to create a feasible design of a grid shell structure and to build up this structure while being capable to understand the core of this interesting phenomenon. As a starting point there was a first workshop organized in cooperation with students and friends, many different materials were used for physical modeling and the very first mesh was assembled. This master thesis documents an experimental pavilion design procedure from the starting design point to a complete built structure and reports on the experiences and knowledge gained. The work describes a step by step workflow of procedures with author's comments, bibliography references and pictorial documentation.
