Abstract
In this study, we analyze drawing documents from the Rietveld Schröder Archif, in order to clarify the characteristics of the construction method of G. Th. Rietveld. The Schröder House is basically a brick structure, however the second floor is constructed of wood reinforced with steel, and has a balcony construction of reinforced concrete slab. The roof of the second floor also uses steel, which allows for the creation of a large open space. This combination of different construction materials is considered to be one of the significant architectural features of Schröder House.
