Mar 29, 2017 at 17:40 comment added Ian Agol Note that there is a version of classifying spaces $\underline{E}G$ where $G$ acts so that compact (i.e. finite) subgroups have (weakly) contractible fixed point sets. Sometimes groups with torsion can have finite-dimensional $\underline{E}G$. ams.org/mathscinet-getitem?mr=1292018

Mar 29, 2017 at 15:57 comment added Mark Grant The answer is no, because the presence of torsion forces $\Gamma$ to have infinite cohomological dimension. See e.g. Ken Brown's "Cohomology of groups", Chapter VIII.2.
