Summary: Following Gromov, the coboundary expansion of building-like complexes is studied. In particular, it is shown that for any \(n \geq 1\), there exists a constant \(\epsilon (n) > 0\) such that for any \(0 \leq k < n\) the \(k\)-th coboundary expansion constant of any \(n\)-dimensional spherical building is at least \(\epsilon (n)\).
