Apart from the farm buildings on display, the Powerhouse Museum had a Walther & Stevenson doll's house in the their Recollect: Models exhibition.(Although as far as I could see, there were no contents.)
There were, however, pine cone trees
and super-giant-sized light switches on the side.
I swear I blogged about the house ages ago when it first arrived at the museum, but damned if I can find it. Instead, I found this awesome blog post from The Powerhouse Museum with great pictures, including ones of the original owner as a child with the house. Enjoy!
