Whether you are renovating an existing house or building a new one, it is time to think about greening your building process. From finding people who are willing to take away existing materials that you are replacing, to finding builders that will help you build green. There are so many more options out there today to consider when you are building or renovating. You can use materials that are either repurposed (such as old wood floors) or are made from sustainably harvested materials. The listings here are by no means exhaustive but they should get you thinking as you embark on your home improvement projects.
