Buda TX is a small but rapidly growing town just south of Austin Texas in Hays County. Greenbuilders, Inc. built quite a few homes in the Elm Grove subdivision there. One can notice which homes by the small 53 gallon wood rain barrels or I can look them up for you in MLS. On the inside, these homes will have foam insulation in various places you should be able to see such as the attic. There are other subdivisions close to Buda TX that have green built homes I can search for.
