For agricultural land we have what 3 PLN / m2 or £0.66
Ok, that's a fair price for pure, empty agricultural land (about 30,000 PLN per hectare). Keep in mind, that's empty arable land with nothing on it. When you start to price arable land which contains a small wooden home, or brick stable, or a wooden barn on it, that totally changes the way you value that per m2 land - it then ranges anywhere between 75,000 PLN to 150,000 PLN per hectare for the reason being you now have a zoned farm plot within and / or adjacent to your agricultural land, which is perfect for renovating or tearing down the old farm house and building a home which replicates the same area on the original foundation. Everyone wants a house or other building on a large plot or arable land, instead of a home on a small 0.20 hectare piece. I've done exactly that, purchased an empty wooden farm house, barn shell, all with electricity and water, on land / forest exceeding 5 hectares and 2 hectares respectively. For the former, I tore down the old wooden house, rebuilt a new brick house consisting of the same area in m2, on a new foundation which was constructed on the same location as the log home's foundation, without any cost of a plan or architect. The same was done with my barn, which is now brick as well. Such properties are rarely ever mentioned here on Polish Forums when discussing the 'Polish Real Estate' market. It's always the same - flats, flats, and flats.
Eventually, Polish agricultural land will reach a fair equilibrium price with that of Western European farms. That means, the price will only go up until a near equilibrium is reached. One major reason is that foreigners still need permission from the Polish interior ministry to purchase farmland and farms in Poland. Once this law is abolished around 2012, you will see demand increase for agricultural land from a new bunch of people...foreigners. That will only bode well for those holding agricultural properties in Poland.
As far as flats in Poland go, there isn't much good news as of now.
