The Story Behind Sebastian Design Build

Andrew Sebastian, owner and founder of Sebastian Design Build, was driven by his love for the outdoors, a passion that took root in his formative years. This deep-seated passion inspired him to embark on a journey to achieve a Bachelor of Landscape Architecture degree from the University of Maryland.

Following his academic pursuits, Andrew's desire to serve his country led him to commit to the Army Reserves, where he honed his skills as a Carpentry and Masonry Specialist. Upon completing his military service, Andrew remained steadfast in following his calling, ultimately leading to the establishment of Sebastian Design Build. He is now not only running the business, but also involved in just about every step of the process, including sales, design, and construction.
