The image is a collection of four architectural drawings on a piece of paper. The drawings are in black and white and appear to be hand-drawn. 

The first drawing on the top left shows a floor plan of a building with a rectangular shape and a flat roof. The floor plan is divided into four sections, each with a different layout. The first section shows the layout of the building, including the ground floor, the second section shows a room with a large window, the third section shows an open space, and the fourth section shows two smaller rooms with a balcony.

In the center of the image, there is a circular drawing with a circular design in the center. The drawing is labeled with the words "Wohnungenbauen" which translates to "Building plans" in English. Below the drawing, there are two smaller drawings of the same building, one on the right side and one in the bottom right corner. The text on the paper is written in German and appears to be a description of the drawings.
