The villages also want a uniform appearance and not house, hole, house without plaster, house without roof, hole in the construction area.

I also find it "antisocial" when everyone's problem is socialized. With us, everything was developed and built quickly. Children also want to move around outside without problems without trucks constantly driving back and forth.

I see it similarly. That means: Either you stick to your plan and wait until the four years are up, or you buy and build now and accept that additional costs will arise due to your spontaneous change of plans. Building must be affordable in every respect, but you are already quite tight regarding your entire financial situation.
