Abstract: Let $ X$ be a separable metric zero-dimensional space for which all nonempty clopen subsets are homeomorphic. We show that, up to homeomorphism, there is at most one space $ Y$ which can be written as an increasing union $ \cup _{n = 1}^\infty {F_n}$ of closed sets so that for all $ n \in {\mathbf{N}}$, $ {F_n}$ is a copy of $ X$ which is nowhere dense in $ {F_{n + 1}}$. If moreover $ X$ contains a closed nowhere dense copy of itself, then $ Y$ is homeomorphic to $ {\mathbf{Q}} \times X$ where $ {\mathbf{Q}}$ denotes the space of rational numbers. This gives us topological characterizations of spaces such as $ {\mathbf{Q}} \times {\mathbf{C}}$ and $ {\mathbf{Q}} \times {\mathbf{P}}$.
