To be honest, you are approaching it the wrong way :-) Of course, you are always allowed to dream, but the essential question is not about a floor plan, but: how the heck do I get a piece of land? And what am I willing, or even able, to pay? It doesn't help if, for example, there is a plot with a highest bid and you win, but then can't afford anything anymore. Unfortunately, your budget also sounds a bit like wishful thinking :(
