I like how the laundry connects to master closet. I think I would move the master to the back and the garage to the front. Then you could have access to the back deck. Extend the grilling porch to the full length of the back of the house, screen it in and add an outdoor fireplace. Perfect floor plan!
This kind of "bumpout" storage can be very useful in a small house, but make sure it's properly sealed so water doesn't get trapped between the walls. - To connect with us, and our community of people from Australia and around the world, learning how to live large in small places, visit us at www.Facebook.com/TinyHousesAustralia
