My thesis discusses the concept of the detached house itself, including its first appearance, its scale and layout, and what qualifies/qualified as a detached house. I describe the layout and construction in more detail through the most characteristic changes of different time periods. I also present these periods in general through their main architectural changes. I mention the opportunities offered by financial differences and political influence (if any) in the area of family homes. I delve into the needs of families and individuals, and explore what detached family houses were used for. Among other aspects, I consider the co-living of generations, the size and functional order of spaces within the house (e.g. order of importance), the use of the garden, additional construction in the garden etc. I discuss the vision and ideology of Frank Lloyd Wright, including his philosophy about detached family homes. I also explore the concept of the ‘Kádár Cube’, thus demonstrating the diversity of the 20th century. The end of my thesis describes the 21st century situation, and as a conclusion, I propose a concept for the ideal detached family house and what it could look like.
