Marnie Oursler
President & Owner of Marnie Custom Homes
As a fifth-generation home builder, Marnie has taken all the skills she learned from generations before her and expanded on them to design and build custom beach homes that bring visions to reality. In 2023 she was awarded the Custom Home Builder of the Year by the National Association of Home Builders (NAHB). This award is the highest honor given within the custom home building industry, and she is the first female recipient, as well as the first Delaware-based builder to receive the esteemed award.
While each home Marnie builds reflects life at the beach in a variety of ways, the main goal is to always fulfill the homeowner’s wants and needs, creating spaces to fit their lifestyle while embracing the natural surroundings of our Delaware beaches.
As soon as a client starts describing their vision, Marnie is already creating the blueprint in her head. With more than 25 years of experience in both building and designing custom beach homes, she knows every aspect of what’s required to build safe, sustainable, and weather-resistant homes while also creating innovative one-of-a-kind spaces that enhance life at the beach for families and their guests. She has built over 130 homes to date throughout the Delaware beach region.

A graduate of the prestigious Global MBA program at Duke University’s Fuqua School of Business, she is a frequent speaker on such issues as building a business, cultivating a mentor, and creating working relationships that truly benefit all involved. Marnie is a member of the Board of Advisors for The Center of Entrepreneurship and Innovation at The Fuqua School of Business at Duke University.
