Native is the most experienced environmentally friendly and efficient builder in Austin, and most likely in Texas. We did a comprehensive search and evaluation of builders before we built our home and they were at the top of the list in solar, rainwater and geothermal, all of whic we wanted. They have done more of all three than all the other builders we contacted combined. And it is all in house, so there is no issue with trying to find a contractor after the home is built. More importantly, they are incredibly good at building. They listened to us, and to our architect, and came up with cost effective and innovative solutions to any problem that came up during the construction. And they stayed in touch with us well after the house was done, in fact they still stay in touch with us to make sure we have no problems. Our house is beautiful, built to last, and costs less than a quarter of the other houses in our neighborhood to maintain. If we ever build another home, Native will build it.
