Is it possible to build my own pension?

{ "#" : "I am a 53-year-old man. I retired early on an annual pension of €30,000. However, the children go to third-level colleges and I have recently taken up a job that pays €40,000 a year." , "b" : "Dilemma:"}

I was hoping that I could build up my own pension using property (preferably abroad) that could supplement my pension later on and that could also turn out to be a holiday ...
