Custom Sustainable Homes

Natural Energy Designs Inc. can build using a variety of materials. We have built houses using strawbale, cob, insulated concrete forms, traditional lumber, recycled materials and other natural materials. We believe in using materials that are locally sourced if possible. We will help in the design phase to utilize the natural resources available. We promote the use of super-insulation, which helps save massive amounts of energy. If you combine this with passive solar heat, you can reduce your heating needs by as much as 75%. We also recommend thermal solar panels for hot water and/or hydronic heat.HerneHouseHerne


We remodel existing houses utilizing sustainable and green practices. NED believes that a remodel should increase the energy efficiency, comfort and resale value of a house. Our focus on remodeling a structure includes: improve insulation, improve heating and cooling systems, remove interior pollutants and improve indoor air quality.
