The picture shows four people in formal dress standing in a modern, light-flooded building. They are standing on a raised walkway with railings, surrounded by large glass windows. The windows extend along the entire length of the corridor and let in plenty of daylight.on the left of the picture is a woman with long, dark hair wearing a black trouser suit. She has her arms crossed in front of her chest and is looking down as if she is pensive. Next to her is a man in a dark blue suit, who is leaning on the railing with both hands and also looking down. Next to him is a woman with blonde hair in a white blazer and beige trousers. To her right is an older man with white hair and a beard, wearing a dark blue suit and interlocking fingers. The four people are discussing ista's building management system. Below the catwalk are large green plants that lend the room a natural element. On the right of the picture you can see a wall with dark red bricks and several doors. The whole space has a modern and open feel, with lots of natural light and a mix of industrial and natural elements.

The picture shows a residential complex in the centre, stretching from the left to the right edge of the picture. The various buildings look very similar on the outside and have a white-orange brick façade. The individual flats have balconies with glass railings. The balconies are separated from each other by frosted glass walls and are furnished differently, giving each flat an individual touch. Most of the visible buildings have four floors, but vary in width so that different numbers of flats are visible on each floor. In the right quarter of the picture, in contrast to the others, another building rises up, which has the same style as the other buildings in the residential complex. A park can be seen in front of the residential complex in the lower half of the picture. Grasses and bushes surround the residential complex, accompanied by a pavement adorned with scattered trees. There are also benches and lanterns on the pavement. An artificial pond can be seen in the bottom left-hand corner, surrounded by a wooden walkway with glass railings. The sunset can be seen on the right-hand edge of the picture, giving the sky a slight colour gradient, from a reddish tone on the right to a bluish tone on the left.
