In this research paper, we studied the evolution of the office over time in Europe and America. Initially we approached the subject by studying a wider sense, the sense of working. We tried to find its definition, but also how this concept can be related to the human being. In today's society, the development of the tertiary sector increased the employees of the office resulting in the immediate need for office space. Focusing on these spaces, we seek answers to questions related to the working conditions of the office such as: what defines a workplace as an office? What are the factors that determine it? How they affect the work and the life outside of it? To answer these questions, we made a historical retrospection of the office starting from the classical antiquity reaching nowadays stressing the basic typologies of the office space. A remarkable phenomenon of Greek reality, is the insertion of the office in the apartments of the block of flats, a structure prevalent in the urban centers of Greece. This led us to further investigation of the relationship between office buildings and block of flats through the aspect of the employee. For this investigation, a questionnaire has been created with anthropocentric content, in which the employee is required to answer questions about his already existing working environment, but also about the desired one. The results of the questionnaire, has been organized into charts for further analysis, which then led us to create a proposal for the offices. This proposal focuses on the immediate environment of the employee, and is independent of the building envelope in which can be placed.
