BETHESDA, MD — August 26, 2026 — The Meridian Group (“TMG”) and Harrison Street Asset Management (“HSAM”), a leading alternative global investment management firm with approximately $109 billion in assets under management, in partnership with HLM Associates, announced the acquisition of the Stoneleigh and Newbrook campuses, a five-building, 431,000-square-foot office portfolio in Chantilly, Virginia.
The acquisition represents a significant investment in one of Northern Virginia’s most important national security and defense corridors and advances TMG and HSAM’s conviction in the growing demand for modern, mission-critical facilities serving the US defense and intelligence communities.
Located in the heart of the Westfields submarket, the portfolio is home to a concentration of defense and intelligence-focused companies. The joint venture plans to invest additional capital in the portfolio to expand its secure-facility capabilities, modernize existing infrastructure and create an environment designed to address the evolving needs of companies supporting national security missions.
“Westfields is an ideal first investment for the platform we have been building,” said Gary Block, CIO at TMG. “We have developed significant expertise around secure facilities and the unique real estate requirements of the defense and intelligence communities. Our goal is to become a landlord of choice for both traditional government contractors and the growing universe of nontraditional defense and technology companies in the markets we serve.”
“National security real estate aligns closely with our strategy of investing in specialized assets where durable mission-driven demand and significant barriers-to-entry create compelling long-term fundamentals,” said Greg Borofsky, Managing Director at Harrison Street Asset Management. “We are pleased to partner with TMG and HLM to enhance this portfolio and position it to meet the evolving needs of defense and intelligence users.”
HSAM and TMG, in partnership with HLM Associates, are pursuing a strategy that benefits from their combined institutional real estate investment and operating expertise with specialized knowledge of secure facilities, government contracting and the requirements of the US intelligence and defense communities.
“Secure facilities are not simply traditional office space with additional construction,” added Colin Madden, VP of Acquisitions at TMG. “We have seen that they require specialized knowledge of accreditation, physical and technical security, construction, operations and the missions of the tenants occupying them. We believe combining that expertise with an institutional real estate platform creates a differentiated offering for the customers we serve.”
