To achieve Arconia style in your apartment, prioritize creating calm, edited spaces with a restrained color palette of warm neutrals accented by jewel tones like emerald. Focus on quality natural materials such as stone surfaces and linen fabrics paired with brass hardware for subtle elegance. Ensure ample natural light and use layered, dimmable lighting to craft a serene atmosphere. Emphasize balance through proportionate furniture layouts and minimal ornamentation, reflecting quiet luxury over ostentation.
