We derive a new family of quantum error-correcting codes. The main technical tool used to do so is the physically intuitive concept of condensation, which is employed to create new domain walls between the quantum double of $\Z_4$ and an instance of the doubled semion phase. Specifically, we provide explicit constructions, first at the lattice-level and then subsequently at the macroscopic logical-level. To provide intuition, we provide a series of explicit examples using the derived topological interfaces. We discuss the code's utility in the burgeoning area of quantum error-correction with an emphasis on the interplay between logical error rates and decoding. We conclude by outlining how such codes' representation and design can be automated. We expect our results, which provide explicit step-by-step instructions in the form of algorithms, to pave the path for new higher-algebraic-dimensional codes to be discovered and implemented in configurations that take advantage of various hardware's distinct strengths.
