Condition: Very good! Bau-Entwurfslehre (1942) is a wartime edition of the famous architectural design manual by Ernst Neufert, published in Berlin by Bauwelt-Verlag. Conceived as a compact reference, the book brings together standards, dimensions, and typical layouts for architectural design—from spatial planning principles and functional relationships to scales for furnishings and building components. With its extensive diagrams and tables, it became one of the most widely used reference “databooks” for architectural practice and education, building on the first edition published in 1936.
