ᐅ Explaining the interpretation of a zoning plan with regard to buildable areas

The following description in the development plan: Garages, parking spaces, and covered parking spaces are permitted as boundary developments within the specified building depth of the buildable plot areas. This permission for boundary development also applies outside the buildable plot areas. Additionally, they are allowed in the areas designated for parking spaces and garages.

Now the questions:
Is it therefore only permitted to build a carport in Plot 1, or is it also allowed across Plot 1 and Plot 2? Are there any legal experts in this forum who could provide a clear answer? Thank you in advance.
