Sejima and Nishizawa have developed their work without explicitly referencing a theoretical discourse. However, they have stated that their housing projects describe their “architectural biography.” This study presents the hypothesis that systemic theories had influenced their housing projects at a spatial and constructive level. With the aim of testing it, the research produces four lines of results. Firstly, we observe that the word system is prominently current in a significant sample of their published texts. We describe how architects like Tominaga, Ito, Taki, and Shinohara, who influenced Sejima when she was still a student, discussed this concept inspired by Christopher Alexander's texts. The second line brings together all the couple's single-family housing projects published between 1987 and 2010 for the first time in a single document, as well as an original graphic-constructive reconstruction of the most outstanding ones. Thirdly, we unveil the emergence of four constructive patterns by applying these theories to the graphic material developed. Finally, we summarize the results in diagrams, showing the frequency, intensity, and continuity of the identified patterns in the four phases throughout the studied period. Verifying the hypothesis facilitates further research relate their domestic work and their other types of projects.

Sejima 和 Nishizawa 在没有明确引用理论论述的情况下发展了他们的工作。然而，他们表示，他们的住房项目描述了他们的“建筑传记”。本研究提出了这样一个假设，即系统理论在空间和建设性层面影响了他们的住房项目。为了对其进行测试，该研究产生了四行结果。首先，我们观察到词系统在他们出版的文本的重要样本中占有突出地位。我们描述了像 Tominaga、Ito、Taki 和 Shinohara 这样的建筑师，他们在 Sejima 还是学生的时候就影响了她，他们讨论了受 Christopher Alexander 文本启发的这个概念。第二行将这对夫妇在 1987 年至 2010 年间首次发布的所有单户住宅项目汇集在一个文件中，以及对最杰出项目的原始图形结构重建。第三，我们通过将这些理论应用于所开发的图形材料，揭示了四种建设性模式的出现。最后，我们在图表中总结了结果，显示了在整个研究期间的四个阶段中识别模式的频率、强度和连续性。
