Awesome photography. This reminds me of a book i used to read back then called Treehouses & Playhouses You Can Build.
I remember this book till now because i saved my money to buy that book, my parents could buy it then, but i was told that what you buy with your money, you would value. So that was how i started buying books myself.
I must say that i like your use of toning.
Are those things hanging from the roof Xmas lights? at first i thought they were plants growing around the building but then, it was not scattered around. (my thoughts) :)
I think that the toning was good because if it was not toned, it would make it seem like a horror house or haunted location :) The whole black and white idea is just perfect.
Thank you for sharing @velimir.
