This is a fun project that takes very little work, and only requires the investment in some packets of Sunflower and Pea Seeds.

Start by laying out the footprint of the house. It can be as small as a 5' by 5' square, or something large are more complex. Dig a small 1" furrow along the outside of the house. Make sure to leave a 3' gap for a door. Plant sunflower seeds at 9-12" intervals along the outline of the house, and cover the furrowws with soil. For thicker walls, dig a second furrow approx 6" outside from the first, and plant the same way. Water the seeds as needed.

After the sunflowers have sprouted, and grown a nice head start (1' or so), plant 3 or 4 bean seeds around each sunflower plant. The bean plants will groww up around the sunflower stalks, filling in the house's walls. To keep the beans growing as big as possible, keep picking the bean pods off before they have a chance to develop. Alternatively, you can plant another large growing annual vine, like Ipomea.

If you want something more elaborate, you can run strong from one side of the house to the other, and let the beans grow along them, creating a roof. If you got an old door lying around, you can sink som posts in the ground, and make a door for your sunflower house.

If you figure out a way to put in windows, attics, or a basement, let me know!
