After seeing that I can buy a Custom Adult Treehouse ($50,000) from the new Neiman Marcus Christmas Book for a staggering $50,0000, I decided to take a trip back to my old treehouse I built when I was 7.

Amazingly, my construction skills as a child were superb, it was still there, high up in the treetops! Although it looked like it had been recently taken over by psychotic squirrels, it was fun to reminisce on all the epic adventures I had as a kid up in that old tree. $50,000 can't bring back priceless memories of carefree times, but if I had that kind of money I would probably spend just a bit more and have Green Head HQ converted to an entire Ewok village amongst the trees. Now that would be cool.

• A former musician (with the 1990s indie rock band Sky Cries Mary), Romero designs and constructs breathtakingly naturalistic sculptures that nestle into branches as if they had grown there.
• The self-taught designer has built more than a dozen tree houses from California to Tuscany, for a list of clients that includes Donna Karan and Sting.
• His first creation was a nestlike construction for an art show in the Pacific Northwest, but he has gone on to develop remarkably diverse, site-specific environments that rest on a system of steel rods (called the Garnier Limb).
• Romero utilizes indigenous wood from naturally fallen trees whenever possible and has incorporated musical elements for some of his branch dwellers.
• Each structure is unique, and all embrace the majesty of the natural world.
