The picture shows a bird's eye view of the city. The picture was taken vertically downwards and shows an intersection from above, with two roads crossing in the centre of the picture. The road running from bottom left to top right is wider and appears to be a main road. It is lined with trees and a green strip on both sides that serves as a cycle path. The intersecting road, which runs from top left to bottom right, is slightly narrower and there are buildings with different roof shapes and colours at the four corners of the intersection. The building on the left has a striking, light brown roof with a round glass dome in the centre. Next to this building you can see a large bus parked on the street. The building at the top has a darker roof and is surrounded by several trees. The buildings on the right and below have red tiled roofs. The building on the right has a few cars in a car park next to it and the streets are quite clean with few vehicles or people to be seen. The green trees along the streets add a touch of nature to the urban environment. Overall, the picture appears calm and orderly, with clean lines and well-maintained urban structures.

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 row of narrow but tall terraced houses. The terraced houses have alternating grey and white façades. On the left you can see a house with a white façade and on the far right a house with a grey façade. They are also always built at different heights, so that there are never two houses of the same height next to each other. All the houses have a large square window front in the upper half, consisting of 30 small square windows. The window front of the fourth house from the right is the only one covered by a blind. All of the houses have four individual windows under the fronts, with two on the left and two on the right below each other. Above the houses you can see the almost completely cloudless blue sky. In the foreground in front of the houses you can see a lawn with many bushes and a total of four trees, three of which can be seen on the left at the edge of the picture and one tree on the right.
