I don't have any recent pics of the goat house, but ours is a 8x12 barn/shed with a 3ft door that I made a simple gate for. We used clear plastic roofing from home depot (can't recall what it's named) and when putting the plywood on the top for the roof, we cut rectangles out to act as sun lights.
What goats are you looking to house? The breed and quantity makes a difference when deciding what you need to build/buy...
I have a boer goat and two lambs in a hut whos front has a half drop down door and half normal opening door. 4' high in front to 3' high in back, '8 wide, 4' deep.... these guys are about 6 months old and almost ready to go to market...
you can catch a glimps of a bit of it on my page under critters. If its of interest I can try and get my dial up at home to load a picture for you!
