I recently got a building block and looking round.
What does this mean? you have building blocks to build your house? What type? how thick?
Also I have heard there will be changes in regards to the permission or
classification of the land , does anybody know more details about it ?
This is the first step, you have to go to the local town hall to answer this, every area is different. We can not answer this.
Gosiaa, this is a big project and it sounds like you have never done this before?.
You need to know what your land is designated for, this is the first point, you must go to the town hall and ask for the general plan, if they have one.
I would recommend finding a good builder and pay him some money and go through EVERYTHING with him.
You will need some architects drawings, but these are easy enough to come by.
Have you water, sewage, gas, electricity on your plot? Usually not.
Is there is an existing house on your plot?
I seriously recommend giving this job to a professional, you will save a lot of money in the long run.
You might think that doing it yourself is cheaper but if you do not know what you are doing it will cost you more.
Even if you have done this sort of thing before , Poland has extreme temperatures and you need the help of professionals, so you don't spend all your money only to find out that it can't survive the winter.
Also they work out the tenders differently.
There is a new law about if you are in a certain area around a town you can apply for building permission and it should be automatic.
Where is your plot, how big is it and what zone is it designated for?
If you have any more specific questions, I will try to help.
I do wish you luck on your project and I am not trying to stop you, I just want to point out the reality of the situation.
