Custom homes have a unique place in the world of new construction, offering an opportunity for experimentation with new eco-friendly materials and design trends that could eventually become common in all newly built homes. At the same time, architects and builders need to match their interest in green design with the desires of their customers.

“The buyers that I work with are mostly interested in sustainability, in building homes that will withstand the elements and last over time,” says Marnie Oursler, host of DIY Network’s “Big Beach Builds” and CEO of Marnie Custom Homes in Bethany Beach, Del.
