About This Mod
The Runaway London CAS Room CC by ellcrze gives your CAS screen a refined, classic look with plenty of character. This background contains tall paneled windows, warm-toned wooden doors, and patterned rugs that set a cozy and sophisticated mood. It also comes with large indoor plants that add greenery and freshness, and a guitar leaning against the mirror for a touch of personality. You’ll find this background in three versions, increasing your styling options in CAS. I highly recommend this Sims 4 CAS mirror background to players who want to feel like they’re in a chic London flat.
