13 Home Design Ideas That Look Expensive But Are Surprisingly Simple

3: Simple Wall Molding

Plain walls can look expensive with one small design change: molding. Thin trim pieces added in rectangular shapes can make a basic wall look like custom interior work. This idea works especially well behind a sofa, bed, or dining table. The wall suddenly feels more structured, more classic, and more complete. You can keep the same paint color for a soft luxury look or use a slightly deeper shade for drama. The result feels high-end, but the idea itself is surprisingly simple and clean.
