The Past

Douglas L Colonell founded King Construction, Inc. in 1997.  After many years of experience working for other respected building companies in Maryland and Washington, DC., Doug Colonell decided to pursue a lifelong dream of owning his own building company. As a young boy, Colonell learned the building business following his grandfather. During high school and college summers, he could be found framing homes earning his tuition.

Doug studied engineering/architecture and business administration in college. Then as a young husband, father and businessman, he studied construction and contract law during night school all while his career working for established building companies prospered. His career included years working in Washington DC and Baltimore constructing interior build outs, base buildings, historic building restoration and luxury homes.  He continued this for years before he was ready to go at it alone.  For Doug, building was in his bloodline – roots stemmed from Italian stone masons to Irish bricklayers and carpenters.   Doug’s grandfather was a popular developer/builder of residential homes and neighborhoods of iconic reputation, but in recognition to his uncle, an architect by trade, a decorated US Air Force fighter pilot, he named the new enterprise after him – “KING” which was his nickname.  

The culture carefully tended by Doug, was one that focused on giving clients the level of service and quality while paying close attention to the details that he himself would demand thus King enjoys steady growth year over year.
