MCH team on beach


Marnie Oursler

Founder and President 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. As host of DIY Network’s Big Beach Builds and HGTV’s Dream Home and years of experience, Marnie has carved out her place among the top builders in the region.

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 20 years 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.

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. She played Division 1 Soccer at the US Naval Academy before transferring to East Carolina University where she played Division 1 Softball and earned her undergraduate degree.
