Nica, Bogdan Cubulating spaces with walls. (English) Zbl 1131.20030 Algebr. Geom. Topol. 4, 297-309 (2004). From the introduction: The elegant notion of a space with walls was introduced by F. Haglund and F. Paulin [Geom. Topol. Monogr. 1, 181-248 (1998; Zbl 0916.51019)]. Prototypical examples of spaces with walls are CAT(0) cube complexes, introduced by M. Gromov [in Essays in group theory, Publ., Math. Sci. Res. Inst. 8, 75-263 (1987; Zbl 0634.20015)]. The purpose of this note is to observe that every space with walls has a canonical embedding in a CAT(0) cube complex and, consequently, a group action on a space with walls extends naturally to a group action on a CAT(0) cube complex. The usefulness of this result is that spaces with walls are often easily identifiable by geometric reasons.
