DIY Outdoor Kitchen
Outdoor brick grill - this needs some sort of area to use as a work/prep station but food tastes so much better when cooked on a real grill like this with wood or charcoal. And the cooled wood remnants can be used to add to your compost pile with the ash being used on your vegetable garden as fertilizer - so this one is a two-fer!

This is a video on a cob oven that smokes less and doesn't burn the front entrance. Also, at the top of the link page is a great video on outhouses with a very efficient compost house design at the end.
Cob Oven by SGNB.com, via Flickr - I like the "shelf" beside it. It would be cool to do on both sides.
