Terrace planning for a corner terraced house with a large garden - What to consider?

So the property was divided into 3 plots for 3 houses. Due to the subdivision, neighbors have a small plot and with house construction they would already exceed the allowed area. All three houses have one access road. This access road is proportionally owned by all three. It was only allowed to be paved with eco-paving. This access road/private street/common area is billed separately, right? For the terrace, I calculate only with my plot and my area.

Name the number of the post where you showed the entire ensemble (cadastral excerpt/aerial photo). For the floor area ratio "assessment," the property counts in the cadastral sense. As far as I interpret it strictly textually, these are three plots lying one behind the other, of which yours is the last one seen from the public access road, and the "access road" is a GFL area (?)

I only just noticed this. That would be a bed practically in the middle of the driveway, it would be difficult to turn around, it would hardly be possible to drive in because it would be tight from both sides. It's hard to explain. But this is on the common area, meaning if there is an inspection, we all have a problem. However, I would also take it to court with this bed, it is outrageous that someone wants to build a bed there, it would significantly obstruct the driveway.

I don't understand a thing. How can you only just notice something on the driveway now? Don't you go outside? Don't you talk to the neighbors? And what does this have to do with your terrace?

No, that is the wrong approach. The floor area ratio is known and as the owner you are obliged to comply with it. The building authorities only enforce what the laws and regulations say...

And even though I really have to be careful myself not to exceed my 40% and have to make some walkways not with paving stones, but with slabs, gravel cells, or grass grids... I think it's good that there is this 40% limit. Because otherwise many would simply pave a 120m² parking lot, a 60m² stone terrace, and maybe 50m² of lawn, otherwise gravel, and that would be it. That cannot be the purpose of having a house...

Sorry, I only just noticed in the development plan that there should be a flowerbed in one spot, which the company didn't build. But that's fine with me; otherwise, we wouldn't be able to fall into the houses, everyone would count it minimally. Maybe we paved 2-3m2 too much there. That's irrelevant for the terrace now.

With us, grass grids are fully counted, as well as eco-pavers, but a town further away has a completely different rule, i.e. if you have used grass grids, you are allowed to pave twice as much as permitted because only 50% is counted. Just to say that much of it is at the discretion of the authorities. Many are allowed to plant 3 trees and pave 30m² more, others have to tear down.

As far as I interpret it purely textually correctly, there are three adjoining properties, of which yours is the last one when seen from the public development road, and the "access" is a GFL area (?)

Yes....I am the last house.
