The illustrations are bright and colourful and easy to understand, but crude, although this may be an adult eye. There are enough details to hook a child in, without them being over complicated.
I wouldn’t consider it a literary great, just a nice filler book to help a child on the way to literacy, that is both identifiable and educational. It is part of a series, which follows the little girl along. It's also one of the very few LGBT picture books available in New Zealand. It is part of series, which follows the same characters through various minor events (such as getting a dog).
This book is pretty hard to find outside of New Zealand. You can keep an eye on Amazon, but otherwise, here are the full details: Harding, B. & Harding, V. (2002). My house (C. Bray-Cotton, Illustrator). Beaconsfield, N.S.W.: Bulldog Books.
