Would the land use plan shared above change your assessment at all?
No.
However, it is not clear to me where the plan comes from. The brown color results from the overlay of the orange areas from the landscape plan with the green area, the origin of which I have not found out.
The landscape plan boundary can certainly be interpreted as a demarcation to the outer area, but you do not want to exceed that anyway. If the green area comes from the land use plan, I would first question who overlaid it with the cadastral map and the landscape plan. But even if the georeferencing is correct, the land use plan has no binding planning law significance. Moreover, its creation scale is not suitable to precisely influence factual building boundaries to the meter. Nevertheless, your planner should prepare for counterarguments from the administration, as the land use plan already provides indications of intended planning.
