Revolutionary, fragmented, against gravity. These are only a few words that can describe the work of Zaha Hadid. Hadid had been highly innovative and groundbreaking through her work for the last 30 years. Her substantive contribution to the field of architecture lies primarily in a series of advances of great importance made in the repertoire of spatial regimentation, as well as in the means used to achieve this. Hadids standing as a global architect is recognized by the most important international institutions. She was the first woman who received the Pritzker Architecture Prize in 2004 and the RIBA s Royal Gold Medal in 2016. The pioneering vision of Zaha Hadid made it possible for her to reset the architecture as well as the design of the 21st century in general. She managed to set her own trajectories, architectural and artistic, only to be followed by other architects and artists. In her work Hadid had been seeking for forms and spaces which result in fluidity and communication between them. This dissertation focuses on the work of Zaha Hadid, the design tools and the design techniques she used. In other words, the reasons why her architecture is considered to be innovative and unique and the means by which this was achieved will be investigated. The main objective is to understand the methodology, the dominant influences during her architecture career and mainly the different patterns that led to these amazing architectural results. An important element is also the evolution of her design philosophy during her career. It is a direct challenge, therefore, to clarify how her design evolved from the fragmented form of the Vitra Fire Station to the fluid spaces of the MAXXI Museum and the prevalence of complexity and fields in the most recent works of her firm.
