Real Estate / Buying building plot/land for building a house in Poland [5]

Hello forum .

I am looking for advice and guidance. I want to buy a plot of land, for the purpose to build a house. There fore I have some questions :)

1. Does anyone know of a guide of the process of buying land for private construction.
2. Does anyone have a 'How to"guide, to obtain planning permission
3. A guide to see if the plot has planning permission ?

Any advice will be helpful

Thank you
