Let $E$ be a regular compact subset of the real line, let $g_{\overline{\mathbb{C}}\setminus E}(z,\infty)$ be the Green function of the complement of $E$ with respect to the extended complex plane $\overline{\mathbb{C}}$ with pole at $\infty$. We construct two examples of sets $E$ of the minimum Hausdorff dimension with $g_{\overline{\mathbb{C}}\setminus E}$ satisfying the H\"older condition with $p=1/2$ either uniformly or locally.

Keywords: Green's function, compact set, Hausdorff dimension, conformal invariants.
