Our Approach

Our Core Values

Integrity
As Robert Gladstone often said, “You can always make more money, but you can never re-make your reputation.” This philosophy is a keystone for our company, and we continue to operate with integrity, transparency, and accountability in everything we do.
Respect
We are in the people business. Whether collaborating across our corporate teams, serving our tenants, residents, and guests, working with neighbors and public officials, or creating meaningful value for our partners and lenders, we bring respect and care to every relationship.
Vision
We believe that real estate investments are not best measured quarter to quarter. We look instead to the long term by creating superior value through a nimble, disciplined, and analytical approach that enables us to anticipate changes in our market and to see opportunities where others might not.
Intention
We bring laser focus to each project we undertake, giving each one the time and attention required to ensure success. We carefully consider how each building integrates into its surroundings and strive authentically to honor the location, the demands of the market, and the needs of the people who live, work, or stay at our properties.

Our History

Beginning with its earliest projects, Quadrangle successfully pioneered locations where growth became inevitable. In its early years, the company developed office and apartment buildings in downtown Washington’s West End, which has since evolved into an active mixed-use sub-market linking the CBD with Georgetown.

The company subsequently helped lead the revitalization of the “nation’s main street” – Pennsylvania Avenue between the White House and the Capitol. In 1980, Quadrangle completed the first new post-World War II private office building on this portion of Pennsylvania Avenue. This was quickly followed by National Place, the then-largest single-phase development in the City’s history, including the first JW Marriott Hotel, 450,000 square feet of office space, a retail center operated initially by The Rouse Company, the restored historic 1700-seat National Theatre, and a 454-space parking garage.

Quadrangle subsequently helped spark development in the historic East End core of downtown Washington. The 897-room Grand Hyatt Hotel and the adjoining Washington Center office building were among the earliest and largest developments in what subsequently became the City’s largest office sub-market. More recently, the company developed the ten-building, two-million-square-foot Mount Vernon Place project in partnership with The Wilkes Company, with office, apartment, and vibrant street-front retail uses, serving as a key link between the East End and NoMa.

In the region’s fast-growing Northern Virginia suburbs, Quadrangle was an early investor in the transformation of Tysons, Virginia, from an auto-oriented office and regional mall location into an active, mixed-use district with all the attributes of a true downtown for Fairfax County.

“Quadrangle is a company that excels in dealing with complexity. They can take on very complicated projects and entitlements and recognize the value that can be created for the company, its partners, investors, and end-users. I have immense respect for the company from top to bottom. It’s a firm with the highest integrity. They go about doing business the right way.”
Norm Jenkins, President, Capstone Development
“We have had an extraordinary collaboration with Quadrangle – I can’t say enough good things. A company tends to reflect the senior leadership in terms of its culture and its values, and that is certainly the case at Quadrangle.”
Charles C. (Sandy) Wilkes, Chairman, The Wilkes Company
“Quadrangle has a solid platform with expertise across all relevant disciplines. Over the past 8 years of our relationship, I have worked closely with employees throughout the Quadrangle organization and found everyone to be professional, disciplined, collaborative, open-minded, and of the highest integrity.”
Carolyn Abbey, Vice President, US Operations, Oxford Properties Group
