Since 1982
Over forty years of one standard.
Many see a home as just another structure — we see a home as our story. Since 1982, the Horizon Builders family, alongside national leaders in the architectural community, has set the benchmark for luxury residential construction across the Mid-Atlantic.
That ingenuity created our own standard of building — a body of internally developed practice refined over forty years, grounded in building science: moisture dynamics, enclosure detailing, and geothermal system design. It is how every Horizon home is built with discipline, craftsmanship, and comfort in mind.
Your home is our story.

Over his 40+year career, a dedication to building science and expertise in critical topics like moisture dynamics, enclosure detailing, and geothermal system design and installation have become second nature.

In Memoriam
Joe Bohm
Founder
A self-proclaimed Army brat, Joe Bohm lived all over the world before his family settled down in Maryland in 1963. Joe attended the University of Maryland where he earned a degree in business and accounting, and subsequently became a CPA. In 1982, Joe met his future business partner, George at a neighborhood gathering subsequently forming Horizon Builders. Joe’s expertise in accounting, finance and business development set the groundwork for Horizons continued success and is a strong complement to George’s construction expertise. This partnership of “bean counter” and “sticks and bricks guy” paved the road to continued success.
In 2017, Joe passed away surrounded by his family and loved ones. His legacy and wisdom lives on. Our friend and mentor will be greatly missed.
