I wouldn’t take plot 80 even as a gift. You have 6(!) neighbors and in the end, you’re completely surrounded by fences, because nobody uses hedges anymore these days. That makes the 468m² seem even smaller, almost like a prison. And if you plant greenery on all the fences on your side, you’ll end up with hardly any space left for the actual garden.
The 468m² is also not enough for a "yard" where 3 or 4 cars can park and leave independently of each other.
And also consider how much you’re actually allowed to pave. I hardly believe that a development plan in 2025 would still allow 60 or 70% of the plot to be paved for a parking lot in front of the house, even if it’s eco-friendly paving.
