I'm not handy enough to pull something like this off, but boy it sure does sound neat:

An accomplished woodworker, [retired social worker Jack] Barnhart dreamed of building a treehouse - but not one of the scrapped-together versions the word conjures up in most people's minds.

The cozy little cottage he was envisioning would put the Swiss Family Robinson to shame, with two staircases, built-in closets and cabinets, a wet bar, high-quality insulated windows, water and electricity, cable TV and a rooftop patio - not to mention table service for six.

And instead of climbing a ladder from the ground, his treehouse would be accessible by a soaring footbridge, connected to the deck of his home some 65 feet away across a ravine.

Sounds like something my semi-retired dad would do, if he weren't already busy racing 600+ hp dirt trucks. No, really!
