Selecting property overwhelms us

Are there elevations in this development area? To which areas/streets is it connected (I see little "context" / "large-scale" embedding)?

It slopes very gently from north to south. Sorry, this is probably a pretty unprofessional answer, but I can't find exact data on that.

It slopes very gently and quite evenly from north to south. This is probably a really poor statement, but I can't find exact data on it.

To the west there is a fairly busy bypass road, behind it an open field. To the north another relief road is being built, behind which are the schools. To the northeast a large supermarket is being remodeled and to the east the city begins. There are noise protection walls in these directions. To the south there is currently a small field which could theoretically be developed at some point, and then an existing settlement.

The decision would be very easy for me: house slightly smaller and [south-facing plot]. Then the budget would also fit. A few more square meters can be well compensated by good architecture. Not a worse location.

Play through the scenario that the project proposes: Your dream house on a plot where it fits and where you want to live for the next 30 years. Nothing else matters for now. During the construction phase, you get to know future neighbors and make friends. A neighbor who is attentive is worth gold.

That's how we would wish it too, unfortunately we somehow lack the imagination to picture a house on one of the plots..

The decision would be very easy for me: house a bit smaller and southern plot. Then the budget fits as well. A few more sqm can be well compensated by good architecture. Not a worse location.

Thanks for the tip! At first, a 30,000 euro difference between, for example, 18 and 51 seems like a lot. And adjacent to the 51, something might eventually be built, unfortunately we don't know that yet. We actually considered exactly that yesterday, but then thought that maybe more money in the house and garden would be more important than in the land? Are we making a mistake in thinking that? Actually, of course, we would prefer to try to get such a southern plot, but thought that would be too utopian in terms of budget. But if you could save through good architecture and it comes out the same... o_O

I would choose 18 to 20 if I couldn't afford the southern plots. Access from the north, place the house as far north as possible and the living area and garden on the bright south to west side. A hedge to the neighbors, if desired.

Or build smaller 140-160 sqm instead of 180 sqm and for that on a desired plot.

30,000€ roughly corresponds to 12 sqm of house. So instead of 180 sqm for 500,000, just 168 sqm for 470,000, which is more than enough...

What determines the allocation? I would have gone about it quite differently tactically and chosen the "least popular" plots to increase my chances of getting any plot at all ;-)
