The picture shows a modern office building on a sunny day. The building is in the centre of the picture and takes up most of the frame. It has a glass and metal façade that reflects the daylight. The structure of the building consists of several rectangular glass windows separated by vertical and horizontal metal struts. The metal struts are in different colours, giving the façade a lively and modern look. In the foreground, at the bottom right of the picture, you can see a tree whose green leaves are brightly illuminated by the sunlight. The leaves partially cover the bottom right corner of the building. The sky is clear and blue with only a few small clouds in the top left of the picture. The sun's rays create lens effects that can be seen as bright, circular reflections in the picture. In the upper left area of the picture, at the edge of the building, a few plants can be seen on a roof garden, bringing a touch of nature into the otherwise urban picture.

The picture shows a modern, open-plan office space where two people are standing in the center of the room. In the background on the left are cupboards containing files and a presentation board. To the right, you can see two white walls raised close together that do not reach the ceiling of the room. A railing is attached to the right-hand wall, which extends to the right-hand side of the picture and to the wall there. The wall of the railing itself is made of a grey grid and the floor is attached to a steel beam that can be seen from the side. The lattice provides a clear view of the black wall behind it. Two large desks can be seen in the center of this elevation, with two chairs on either side. On the right-hand side, against the brick wall, there is another desk with a chair and a passageway in the wall. In the foreground you can see two people walking towards the cupboards on the left. These two people are only vaguely recognizable as they are in motion and therefore blurry. In front of the railing in the center of the picture are two large tables that have been placed opposite each other and form a large group of tables. There are two chairs to the left and right of the group of tables. Three plants can be seen on the right-hand edge of the picture, their branches protruding into the picture. In the center of the picture, a younger man is standing next to a younger woman, right before the group of tables. The man has short black hair and a black beard and is wearing a black jacket with grey trousers and brown shoes. The woman has open red wavy hair and is wearing a white blouse, a grey metallic skirt and white pumps.
