For beginers, any suggestions?



Any good reference for Tits Building?
A good reference is Ken Brown and Peter Abramenko's "Buildings" (there is also the first edition freely available at <http://www.math.cornell.edu/~kbrown/buildings/>). Otherwise, you may want to look at Tits' "Reductive groups over local fields" from the Corvallis 1979 proceedings (see [Corvallis 1979 proceedings](https://mathoverflow.net/questions/73166)).
