Don't heat up your house in the summer, save space, and enjoy the outdoors! I've seen a few tiny houses with their bathrooms separated outdoors (like my own Vermont cabin), so why not an outdoor seasonal kitchen?
Here's a link for free plans (you have to sign up/enter your email) for a design from a former Eagle Scout for a scout patrol box- otherwise known as a camp kitchen box. Its portable, closes tight to keep animals out at night (well, not bear-sized ones), and could even be used for tailgating, an outdoor mini-workshop, and who knows what else.
