Gestion immo conforme

The picture shows a modern lobby or waiting area with an impressive glass front that offers a view of an urban landscape. In the foreground of the picture are two plain black benches standing on a large beige carpet. The benches are arranged symmetrically to each other, one on the left and one on the right, leaving an empty space between them. The floor is made of polished white tiles that reflect the surroundings and the incoming light, creating a bright and inviting impression. The glass wall in the background consists of several tall, narrow panels that reach up to the ceiling and are connected by metal struts. Green, lush vegetation can be seen through the glass wall, contrasting with the tall, modern office buildings in the background. The buildings have different architectural styles and reflect the light in different ways, giving the scene depth and dynamism. The left side shows a striking building with a characteristic diagonal structure, while the right side shows several high-rise buildings with glass facades. The sun shines into the picture from the top right, bathing the scene in a warm, golden light.

The picture shows a woman standing at a silver railing and looking at a view of many skyscrapers. She has long brown hair tied back in a ponytail and is wearing a black jacket. She is standing with her back to the viewer. The skyscrapers are close together and all have either complete window fronts or many rows of windows stretching through the entire building. The sun shines on the windows of some of the buildings, while the sun shines only partially on the other buildings, because some of the other skyscrapers are casting shadows on them.

The picture shows a close-up of the keyboard of a laptop, which is illuminated by warm rays of sunlight from the background. The screen of the laptop is on the left edge of the picture and a woman in a dark blue shirt can be seen sitting in a blur on the right edge. Her hands are resting lightly on the keys of the laptop. The background of the picture is very blurred, but you can easily recognise the walls of a room and a window through which the sun's rays shine.
