Reminds me when we purchased our first place in 2004 we had a great view there was a piece of land in front of us, when I asked our estate agent if they would build on it his reply was, there are no plans at the moment but it is prime building land and someone will build on it.
Speaking to others who had purchased on the same complex from other agents I was told my agent does not know what he is talking about, it is going to be a car park for our complex. Two years later we had a three storey car park complete with windows and balconies.
