We are delighted to announce that our groundbreaking 6+ acre project, The Stacks, in Washington, DC, has won NAIOP DC's Best Real Transaction award for deals over $25 million. Congratulations to all involved in this transformative endeavor.

Project Milestone: The Stacks, our 2 million square foot, multi-phased development in DC, has bottomed out with the excavation of 220,000 cubic yards (or 19,000 truckloads!) of dirt and the pouring of the mat foundation. Now the building begins!

Meet our bike-enthusiast, Director of Construction Management, Bill. Bill oversees all construction activity on our projects and sets our high standards for delivering projects on time and on budget.

Fun fact: all of our multifamily and hospitality projects are furry friend friendly.

Vision in Action: The key to East Market was creating a special place in the Philadelphia community defined by active, pedestrian-oriented walkways and street life, resulting in a dynamic twenty-four-hour hub of activity.

A team favorite for happy hour and oysters, the outdoor patio at The Wayward within our East Market development has been named one of the best in the city.

Meet our newest Construction Manager, Daniel. Keeping our projects in motion, Daniel manages all stages of the daily construction-related activities from inception to completion.

Earlier this year, we kicked off the construction of The Stacks in D.C. with a ceremonial "Stacking Ceremony." Years in the making, this landmark development exemplifies our commitment to complex, challenging, and multifaceted projects that transform communities.

Vision in Action: We prioritize human-scale activations and the creation of connections. #TheBlocLA

From large celebrations with music, food trucks, and vendors to semiprivate tenant events and outdoor fitness classes, the dynamic streetscape of our East Market development was created with the goal of being a walkable, livable, and desirable area for the community.

No two of our buildings or projects are alike, yet they all adhere to an established set of design principles that prioritize human-scale activation and the creation of connections.

We use art as a form of connection and community. In partnership with Mural Arts of Philadelphia, we transform empty window space at our East Market development into dynamic, bright splashes of color by local Philadelphia artists.

We are a forward-thinking team of developers and architects, engineers, and analysts with a variety of backgrounds and experiences. Our varied backgrounds and interests influence the vision for the dynamic communities we develop.

Located in the historic 1896-built Stephen Girard Building, our team partnered with Avroko and the TaTar Art Projects to ensure the recently renovated, Canopy by Hilton Center City Philadelphia hotel pays homage to the area's art-focused roots.

Before and After - 1100 Ludlow is our 200,000 SF redevelopment project that transformed a one-hundred-year-old warehouse structure into a unique loft-style Class-A office building catering to Philadelphia’s creative, tech, and co-working industries.

Last month, we topped off the Jefferson Health Specialty Care Pavilion, marking the final piece in our @EastMarketPhl development project vision. Thank you for sharing, @phillymag and Sandy Smith. Read more: phillymag.com/property/2022/…
