Only Murders in the Building reflects modern interior design trends by embracing quiet luxury and restrained glamour instead of flashy opulence. The show's Arconia interiors favor serene, edited color palettes, natural materials like linen and stone, and thoughtfully curated furnishings. This subtle, lived-in aesthetic aligns with 2025’s trend toward sustainable, durable design that balances star power with comfort. Spaces are crafted to support daily life while showcasing timeless architecture and soft lighting for a calm, inviting atmosphere.
