While I do have several tin litho dolls houses, I've never really warmed to those produced by the American company Marx. Not sure why. But it seems that they also produced a plastic dolls' house in 1965 called the Imagination dollhouse. I don't have many reference books on 20th century dolls houses, so I've just discovered this house on US ebay, where there is one listed at the moment:
I love the rich combination of colours, and the shapes in the window panels:
The house itself is made of transparent coloured plastic panels which can be assembled in different configurations - a bit like the Bozart Kaleidoscope house, with more scope for changing the layout of the rooms and shape of the house.
The ebay auction is listed with shipping to the UK, so perhaps they'd ship to Australia - but I suspect the final price will be very high, even without the cost of shipping it.
Update: The house sold for only US $204.49, which does not seem much considering it was fully furnished and came with original instructions.
I've just come across another Marx Imagination house, owned by Kathy, while browsing through minimodern's blog archive. Kathy has furnished hers spectacularly with wonderful retro furniture and accessories by a whole lot of different brands, rather than using the moulded plastic Marx Imagination furniture. I love it!
