The architect’s house, the home the architect builds for himself, is a tool more powerful than one would imagine at first. As being the client, as well as the designer, the architect has hardly any constraints during the design and construction process, besides his own wishes. He can use his own house for instance as a unique opportunity for a technological or architectural experiment and cultivate his sense of “entrepreneurial daring” to the fullest. The house can also become a manifest, a pilot project, a masterpiece or turning point in the architect his career. Thereby it represents the best possible business card within the profession.
