How to properly house a Flemish Giant rabbit outdoors?

I'm (most likely) getting a baby Flemish Giant in a few weeks. I've researched rabbits for months now, and I'm pretty well educated. I'm pretty familiar with the Giant's temperament and grooming needs, but as far as housing goes, I'm not so sure. I have no choice but to keep the rabbit outside for a number of reasons. I have a Black Lab/Golden Retriever mix that would probably try to eat the rabbit and a Shih-Tzu that would definitely pester the rabbit if kept indoors. My grandparents aren't very fond of the idea of a rabbit living inside their home, nor is my mother. Outside we have a medium-sized deck that is closed off (the rabbit wouldn't be able to escape and no predators could get in. Only small birds and squirrels would be able to get in, but they usually don't come near the deck at all) and would be perfect for the rabbit. My initial plan was to build a large hutch where the food and litter box (if I can successfully litter train it) would be placed. During the day I would leave the door to the hutch open so the rabbit could go in and out of the hutch as it pleased. At night I would put my rabbit in the hutch with the door closed, and that is where it would sleep. I was just wondering if this is a good plan or not. Any additional information on the breed or just rabbits in general would be nice, too.
