For many of us, our first discovery of building or decorating came from treehouses or playhouses.

My dad built our first treehouse from plywood in the paddock next to our house. I can still remember my sister and mine's wonder that our Dad could build a house - a small house, admittedly, but a whole house nonetheless.

Now buildings are my day job, but I still find myself lost in wonder at them sometimes - especially the likes of the treehouses we feature in this fortnight's newsletter.
