For the child who has everything but still wants more - how about getting them a tree MANSION for their birthday?
Retired architect James Curvan, from Terrell, Texas, builds these elaborate play areas for his friends' children - and they are so amazing, the parents must be tempted to do a house swap with their kids!
James let his imagination run riot to create a complex building with a walkway, stairs, a ladder and a slide as possible options for getting in and out. The interior is no less deluxe and well-thought out.
The children can admire the scaled down fireplace, the wallpaper, telephone and pint-sized wooden furniture that make the treehouse so cosy.
For warm weather, there is a table and chair set on the balcony or a separate shaded platform in the other tree, reached by a treetop walkway.
The more adventurous children can also play on the built-in climbing wall and zipwire all in their own back garden.
James told County Line magazine: "The kids are the key to making a playhouse that kids like.
"They like certain colours, certain animals, and other things. I listen to what they want and then design from that."
