  We propose an ideal building of microscopic configurations for observed black
holes from the compactification of Einstein gravity plus a positive
cosmological constant in five dimensions on a circle and then compute their
statistical entropy. To compute the statistical entropy in this work is applied
to general black holes independent of the symmetries of the black hole solution
such as the spherical symmetry and going beyond the class of special black
holes that are supersymmetric and (near-)extremal as well as have exotic
charges. The statistical entropy of black holes includes the Bekenstein-Hawking
area term at leading order and sub-leading exponential corrections. We find a
new exponential correction which is more meaningful than that found previously
in the literature.
