I've been searching for the name of this type of space for a while and have been reduced to asking the question here. It's not a square (usually located in a city around residential areas) and it's not a park. It's just open space usually located in industrial zones or, for example, outside of a terminal. I thought "esplanade" would work, but I want to make sure there's not a more precise word.
It's a rather large area around a factory. Example picture from Forbes
