Over the years, Washington Landmark has created a number of renovated or new buildings that have later sold to the general public. We believe in honesty without hesitation and the strengthening of every customer relationship through our timeless developments.

Karl Voglmayr

J. Karl A. Voglmayr “Karl” is the founder of Washington Landmark Construction LLC (WLC), a DC-based real estate development company specializing in the construction of single family homes and restoration of multi-unit historic buildings. In a relatively short-time, Karl has made WLC an award winning firm while at the same time expanding his career from design and construction to teaching. He is presently an adjunct professor at Georgetown University’s School of Continuing Studies where he brings his expertise in all phases of real estate development acquired from close to 30-years’ experience in the region’s construction and development industry.

In 2017, WLC won the prestigious Montgomery County Planning Department Design Excellence Award for its innovative design and construction of the dilapidated 100 year-old Grecian-styled gymnasium at the National Park Seminary (NPS) in Silver Spring, Maryland. Prior to this award, the now 12-unit state-of-the-art condominium complex received the county’s 2015 Historic Preservation Award for its modernizing design approach, which executed successfully the adaptation of the Grecian architectural design to accommodate modern conveniences. Presently, WLC has undertaken a similar project to convert the Power Plant at NPS, which consists of three historically designated buildings – the Power Plant, Practice House and Fire House – into 14 distinctive condominiums.

Karl began his real estate career as a superintendent for Trammell Crow Company, the largest commercial real estate developer in the United States and became one of its youngest project managers before founding Washington Landmark in 1992. He has constructed more than 20 unique architecturally-designed single family homes in the Washington, DC area for clients. On the development side, Karl built or repurposed numerous buildings, which include high-rises, boutique condominium buildings, and numerous single family home conversions.

Karl graduated with a Bachelor of Arts degree in Economics and Comparative Politics from Clark University in Worcester, MA and holds a Master’s in Administrative Science from Johns Hopkins University in Washington, DC. Karl resides with his wife, Lorrette and their three children: Alexander, Bridget, and Peter, in the District’s American University Park neighborhood.
