Windows serve as the direct interface between the interior of a building and its public enviroment. Visual relationships through a window offer the opportunity to establish contact with the outside world and experience the widest variety of impressions. In recent architectural history, windows emphasizing seeing and being seen have melted the border between interior and exterior and led to a new interpretation of the concept of a room. This book presents a series of remarkable solutions for this issue. It focuses on a number of selected examples from various areas that document a wide spectrum, record current trends and offer inspiration. An index with the contact dates of the designers is enclosed.
