An original architectural blueprint by Walter Gropius, detailing elevations and wall sections for a 1940s Philadelphia building project.

This architectural blueprint documents a specific project for a building addition and alterations in Philadelphia, dated between 1944 and 1946. The drawing is attributed to the office of Walter Gropius, the German architect who founded the Bauhaus school and later emigrated to the United States to lead the architecture department at Harvard University. The document displays a technical elevation of a structure, alongside a detailed typical wall section, providing a clear view of the construction methodology employed during this period of mid-century industrial development.

The aesthetic of the print is defined by the stark contrast of white lines against a deep blue ground, a standard medium for architectural reproduction in the mid-twentieth century. The elevation reveals a functionalist approach, characterised by a repetitive grid of windows and structural bays. The wall section on the right side of the sheet offers a cross-sectional analysis of the building envelope, detailing the assembly of materials and the structural logic required for the addition.

As a piece of historical documentation, this print captures the precise, utilitarian nature of post-war American architectural practice. The inclusion of technical annotations, scale references, and the formal title block provides insight into the rigorous standards of the Gropius office. The work is devoid of decorative flourish, focusing instead on the clarity of form and the efficiency of construction. It serves as a record of the technical processes that shaped the built environment of the era, reflecting the influence of the International Style on American commercial and industrial architecture. The print is presented here as a high-quality reproduction, maintaining the original scale and technical detail of the architectural drafting process.
