Timmerwerk in Amsterdam

Hello, We would like to make a custom shelf with cabinets to fit in our office room. There would also be a sliding door to be added if you are able to do such work. I added a photo of the current room, a picture of how it would look like, and the approx dimensions. I forgot to add one dimension on the drawing: the depth of the cabinets and shelf would be 44cm to match the side wall length next to the window (see picture). We are thinking about light oak wood, but is not set in stone.
