We conjecture that a group G admits a finite‐dimensional classifying space for proper actions if and only if the Gorenstein projective dimension of G is finite. We verify the one‐dimensional case of this conjecture. Some evidence are given for the hypothesis that the Gorenstein projective ℤG ‐modules are precisely Benson's class of cofibrant modules.
