I remember walking into my friend's 11-year-old son's room last year. It screamed little kid—bright blues, plastic toys everywhere. He hated it. We spent a weekend making it cozy but grown-up. Now he actually hangs out there.
That shift? Huge. Pre-teens want rooms that feel like theirs, not hand-me-downs.
I've done five of these makeovers. Simple swaps make the biggest difference.
