The Hilde Westrom Architectural Collection consist of biographical information about Westrom's career and personal life, original watercolors she painted after her retirement, articles written by her and about her, photographs of Westrom and her buildings, architectural drawings for nine of her projects, and some professional conference papers presented by other women at the 1984 UIFA meeting in Berlin.

The biographical information about Westrom includes vitae information and a portfolio scrapbook that lists her major works with accompanying articles and images. The "Interbau" model apartment is featured. In addition to the material about what she created in her professional career, this collection contains six landscape watercolors that Westrom painted during her retirement.

Articles written by Westrom review the situation of housewives and possible house plans for family living. There is also an autobiographical account of her life and philosophy. The articles about her include newspaper articles about her projects in the 1960s and 70s and articles about the exhibition of her work in 2000. Photographs in the collection show Westrom at professional gatherings, as well as a 1957 cornerstone ceremony, interior views of her 1957 "Interbau" model home, and exterior views of buildings, many of which are not identified.

Drawings for nine of Westrom's projects are included in this collection, representing schools, a university dormitory, housing projects, a parsonage, an apartment with an atelier and a home for the elderly. Drawings for each project may include site layouts, elevations, cross-sections and floor plans.

Westrom also retained copies of the papers that speakers presented at the 1984 UIFA Congress held in Berlin. These papers and brief biographical sketches of four Czech women architects are also available in this collection.
