TITLE: Understanding how to construct Bruhat-Tits buildings for non-split groups by Galois descent
QUESTION [7 upvotes]: Is there any way to get on top of the procedure for constructing Bruhat-Tits buildings for non-split groups over a non-archimedean local field $k$, by Galois descent, other than reading both the Bruhat-Tits articles "Groupes réductifs sur un corps local"? In particular is there any exposition which is written in English?

REPLY [8 votes]: There is a forthcoming book "Descent in buildings" by Bernhard Mühlherr, Holger Petersson and Richard Weiss, which should appear soon (published by Princeton University Press). See http://press.princeton.edu/titles/10649.html. It addresses exactly this issue, from a very building-theoretical point of view.

REPLY [6 votes]: Jiu-Kang Yu has an article "Bruhat-Tits Theory and Buildings" which has appeared in  "Ottawa Lectures on Admissible Representations of Reductive $p$-adic Groups". It doesn't directly address your question, instead it contains a guide to the literature on Bruhat-Tits buildings.
There is a 26 page pdf version of Yu's article. The published version contains a bit more information, but not a lot more (a few more references are added, plus a short introduction, plus the typesetting is updated). Unfortunately the printed version is  hard to find.
