One of the dolls' houses in the 1999/2000 exhibition and book Dolls' Houses in Australia 1870-1950, called Casa Mañana by its current owner, was constructed in the 'ocean liner' style popular in the 1930s and '40s.
Some plans for a very similar house just popped up on ebay, and I wouldn't be surprised if Casa Mañana was built following these plans:
The auction contained an excerpt from the text:
"Just think of the pleasure the youngsters will get from this modern doll house! Up-to-the-minute styling makes it easy to build, for simplicity is always a feature of modern design."
Given dimensions: 29 x 18 x 20.
The plans were published in 1937, when the ocean liner style was at its height. Casa Mañana was thought to be made c 1950 - perhaps it's a little older, if it was made following these plans.
