The house the architect builds for himself and his famAîly can be considered as a unique, autobiographical reÂcord. Because of the twofold role of being both designAêr and client, the architect can seize the opportunity to conceive his house as a manifesto, a technological experiment or as a turning point in his career. MoreAôver, he can also deploy his house as a commercial tool to attract future clients; as a life-size business card which demonstrates his professional expertise and ambitions. Rcscarch into this spccific bu i ldi ng type has rcvealed over 330 architects' houses built in the Brussels CapiÂtal Region between 1830 and 1970. A geographical and chronological analysis showed that many architects used their own home to take part in, or even to anÂticipate on, evolutions related to the extension of the urban fabric or the development of new architectural styles like art nouvcau or modernism. To fully grasp the significance of the architect's house as a specific building type, we critically reflect on the characteristics that distinguish this project from othAêr buildings. As such, we have identified five inherent characteristics, namely the position of the house withAîn the ocuvrc of the architect, the relationship with the future clientele, the house as working place, how the architect engages his professional network, and finally how the house relates to an earlier or future version. For instance, the ambitions and impact of a house built at the beginning or near the end of the career will be very different. It can also be particularly interesting to sec whether the architect uses the house to engage with his clients in a socio-economic or geographical way. Whether and how the architect integrates an architectural studio or office in the house is often also tcllingfor how he practices architecÂture, as is the way he collaborates with other building actors during the design. And if an architect built several houses for himself, the comparison of these projects generates a deeper understanding of the perÂsonal ambitions, professional development and the different space-time contexts in which the architect operates. Through the lens of these relationships, we discuss how architects' houses can evolve into a business card. Therefore, in relation to the architectural and profesÂsional aspirations of the architects, especially the role and impact of their own houses on their future portfolio is investigated by means of three case studies; the own house of Henri Van Masscnhovc (Brussels, 1894), Gustavc Strauvcn (Brussels, 1902), and Luc Schuitcn (Ovcrijsc, 1976). Each of these houses illustrates a difÂferent ambition and tells a unique story embedded in a particular context. Ranging from a model house to a personal statement, they all show the various ways in which architects' houses can become a harbinger for the architect's future work and how it can function as a business card, both accidentally as intentionally. As such, the analysis based on those five inherent characÂteristics enables us to fathom the added value of the architect's house as a specific building type.
