Life Form houses are not being buit anymore, they were the brainchild of Mitchell's son, an architect, but they stopped building them in the 80's I think. You will only find existing houses. I actually found 4 Life Form houses for sale (I added the two others on the other life form post since I had created this one by mistake). Most of them are in the 77381 zip code which is technically Spring and not the Woodlands. I did my seach on the HAR website.
