As I suspect you know, the poster meant 5,000 an "ara" not m2.
Nope, he made it quite clear he was talking about 5k per m2. Even restated that the total cost per m2 would be 9k.
If you delved deeper into these ads you might understand why they are this price.
This is what country land is like. They are narrow strips so that village houses can be classified as farms, you get the land but are 20meters from your neighbours for security/social reasons. The advantage of being a farmer (owning over 1ha) means that you get the income from farming and the state pension, healthcare and no tax returns for a 900pln payment per year. The preferential treatment for farmers is so unfair to normal citizens that the EU has demanded Poland stop it.
I can show you plots of land with direct access to tarmac road and a few hundred meters from the S7 highway between Krakow/Warsaw. My own land is going to have a road built (to the S7) and rezoned to Agro-building. Even then I would only value it 20-30pln/m2 in 8-10,000m2 plots (assuming I can split it). Its current value with a non-metalled road is about 4PLN/m2 as farm land. I guess..
The point is there are lots of cheap land, lots of new, quality roads being built, but its completely different to city land and development and you (assuming you are not Polish) are not even allowed to purchase until 2016 anyway. Of course it is of no interest to you.
The "little" things that I would expect an IT consultant to forget.
Stop the personal insults, I'm at least a qualified engineer, with a degree recognised by the IEEE. Are you a civil engineer? describing yourself as developer would suggest not. Building is an engineering endeavour, hardly rocket science, but it follows the same principles whatever the discipline. The real difference is practical experience, of course, and if the most hassle you have is moving a telegraph pole then I'd say you are lucky.
"Even the figures you quote for hassles don't make a dent on the overall cost... your 6k/m2 figure is higher than other builders are selling for, including land, and higher than the sales price for all sorts of completed property."
One or both of us misunderstood the other. The OP asked what the price was for building,
excluding land. I'm saying it around 3k (excluding fixtures and fitting such as kitchen, bathroom) but including a septic tank/power.
I think I'll contact towncountry.pl and get exact specification of what is included.
