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.
