The north side will be 8 feet below ground level at the bottom of the fish tank. The entire green house (for lack of better words) will be 4 foot below ground level, except the south end, it will be at ground level. I am going to fill the sides in all the way. Kind of using the earth for both. The north side will be compeletly blocked from the wind, the hill is higher near my house than it is at the site, and my house is about 50 yards north of where I am going to build it. I figure the fish tank being at it's highest point 4 feet below ground it will keep the water at a very constant temp, and in the winter the warmth from the fish tank will help to warm the green house, since in winter it will be covered up.
