The picture shows a man sitting on a balcony in an urban environment. He is wearing a dark blue suit and a white shirt and is sitting relaxed at a small black table on the lower half in the centre of the picture. On the table in front of him are a laptop, a notepad with a pen and a coffee mug. The man has rested his legs on the balcony railing and is holding a telephone in his left hand while talking on the phone. The balcony is richly decorated with plants. On the left of the picture, climbing plants stretch up the wall, taking up almost the entire left side of the picture. Below the climbing plants are several pots of flowering plants and greenery arranged along the floor of the balcony. Above the man, stretched across the balcony, is a string of lights with several light bulbs that extends from the top left-hand corner to the right-hand side of the picture. In the background you can see a row of multi-storey buildings in various shades of yellow stretching across the top and centre of the picture. Behind the buildings is a park-like landscape with many trees that further break up the background. The sun seems to be either rising or setting, giving the picture a warm, golden glow. The view from the balcony extends over the roofs of the city.

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.
