The above Treehouse was originally a Fort for two boys that had grown and the new owners of the fort was two sisters.  These clients had some wonderful ideas on the design of their new home and what they hoped could be achieved with the renovation.

It was a 3 sided Lean-To Style Fort with a half a roof.  There requirements where to double the square footage and completely enclose the structure, with doors and windows.  Keeping the trap door and rope ladder, but as well add an easy access staircase wrapping around the outside of the structure for their potential (play) client friends to purchase their (play) food.

One of the pleasures of working for such astute clients was the freedoms that they allowed me to be creative.

They wanted a basket attached to a rope pully so that their parents could send them fresh cookies and drinks while they were playing in there Treehouse.  So I thought, wouldn't it be cool if I had placed a hidden door, behind a hinged bookcase up against a wall that hid the passage way.  As well I provided them with a secrete magnetic key, that only they could open and pry away the hinged bookcase to reveal the hidden passage way and basket of goodies.  

The Dutch door was an idea for them to serve their customers and I left building the wrap around staircase until last, telling my customers, it was for safety purposes, as I didn't want anyone up their climbing around until I was finished the project.  but truth be told, the real reason I left the staircase until last, was so that I could be a kid again, climbing around a tree all day :)  Also &75.00 per hour... I would of done it for Free!
