A home-renovation expert is highlighted across reporting as pointing to a trend in celebrities choosing unconventional or niche design choices that may affect home value. The articles discuss examples that include Demi Moore’s unusual bathroom layout, described as cluttered or oddly arranged, and Kim Kardashian’s home features characterized as less functional, such as flat sinks. The reporting also references Paris Hilton’s pet-focused “mansion” or specialized pet setup, described as highly niche. Across the sources, the common theme is that design decisions driven by personal taste or distinct lifestyle needs can introduce features that may not appeal broadly to future buyers. The coverage does not present a single, verified valuation figure for any specific property; instead, it focuses on the expert’s assessment that certain renovation choices could reduce buyer appeal and therefore potentially devalue homes. The articles portray these celebrity cases as illustrations of how unconventional renovations are becoming more visible and, according to the expert, may carry financial downsides.
