Multiple Award-Winning Green Builder


Additions & Renovations

Adding on new additions or renovating your current house is an excellent way to increase your square footage but you will want to make sure that addition is built with an energy efficient strategy.

We help you with all aspects of designing a green home addition from the type of materials used in your construction to which renewable would benefit you the most. Since Energy Star renovations reduce your energy costs, you’ll know that your new indoor environment is not only functional but also low maintenance!

All of our additions & renovations have improved the energy efficiency of the home, along with adding the space the client requested. In most cases, making these energy changes in conjunction with the space changes prevented our client from having to increase their mechanical systems to meet the needs of the additional space.

Below are a few before and after examples of our additions and renovations:
