Privacy violations are one of the main problems encountered in technology-enhanced environments. In order to design privacy-preserving technologies it is important to understand the social, psychological, and architectural aspects of privacy and incorporate them into the development process of future systems. Therefore, this paper illustrates the effects of privacy on human beings and explains why it is so important to maintain an individual private sphere. In the second part, the paper takes a closer look at the physical means, which are used to create an atmosphere of privacy within buildings and shows different ways of achieving personal privacy in architectural spaces.
