Architects' Data starts with the basics of designing for a new building project, before moving on to covering everything an architect needs to know. It also looks at the design styles and specifications for creating different types of structures, such as those made for residential, religious, cultural, sports, medical, and other types of occupation.

In 1934 he became the resident architect of Vereinigte Lausitzer Glaswerke (United Lusatia Glassworks). He designed the private home of its director Dr. Kindt (with colour glass by Charles Crodel) and various housing, office, and factory buildings in Weißwasser, Tschernitz and Kamenz. At the same time he worked on his Architects' Data, which was published in March 1936 and which remains an essential reference work, having been translated into 18 languages. In 1936 traveled to New York and Taliesin to visit Frank Lloyd Wright and gauge his prospects of finding work in the United States. But in New York he was notified of the enormous success of the first edition of his book and returned to Berlin to prepare the second edition. New industrial commissions for his studio led to his decision to remain in Germany. In 1939 he was appointed by Albert Speer to work on the standardization of German industrial architecture. Covers user requirements, planning criteria, basic dimensions, and considerations of function and sitingErnst Neufert was a German architect who is known as an assistant of Walter Gropius, as a teacher and member of various standardization organizations, and especially for his essential handbook Architects' Data.

Neufert's Architects' Data was the first book I bought when I started my studies in architecture. It was invaluable for me then and it is still a useful aid in my designs."The book is conceived to help the initial design of buildings by providing extensive information about spatial requirements. Dealing mostly with ergonomics and with functional building layouts, thousands of drawings illustrate the text, organised according to building typologies. Weighting now slightly less than two kilograms, it has been continuously updated. Architects' Data provides an essential reference for the initial design and planning of a building project. Organised largely by building type, and with over 6000 diagrams, it provides a mass of data on spatial requirements and also covers planning criteria and considerations of function and siting.
