Stream Realty Partners Drives Leasing Momentum at Addison Office Property
DALLAS – July 1, 2026 – Stream Realty Partners, a national commercial real estate firm offering an integrated platform of services, announces the successful repositioning of One Hanover, a 196,656-square-foot office building located at 16633 North Dallas Parkway in Addison, Texas. Following a comprehensive multi-million-dollar investment in the property, occupancy has increased from approximately 40% to nearly 70%.
Since acquiring the property in the fourth quarter of 2023, New York Life Investment Management has invested more than $4.4 million in improvements designed to enhance the tenant experience and better align the asset with evolving occupier preferences. New York Life worked together with Stream to deliver upgrades to the common areas, new on-site amenities, and multiple floors of move-in-ready office suites.
Within 12 months of delivering the initial speculative office suites, all available spaces were leased, and more than 60% of a future phase of flexible spec suites on the fifth floor was preleased. Stream has completed more than 56,000 square feet of new leases at the property, including commitments from Plutus Health, a healthcare revenue cycle management company, which leased 6,865 square feet; AvalonBay Communities, a publicly traded multifamily REIT, which leased 6,587 square feet; Gurian PLLC, a Dallas-based CPA and advisory firm, which leased 6,718 square feet; Reliance Standard Life Insurance, a provider of insurance and financial protection products, which leased 7,345 square feet; 1847 Financial, a financial planning and wealth management firm affiliated with Penn Mutual, which leased 4,444 square feet; JLK Rosenberger, LLP, a certified public accounting firm, which leased 4,423 square feet; and Rolfson Oil, North America’s largest oilfield-only fueling solutions provider, which leased 19,781 square feet.
“The office market remains highly selective, but tenants continue to respond to properties that offer a reimagined experience with high-quality spaces that can accommodate near-term move-in dates,” said Chase Lopez, Senior Vice President at Stream. “At One Hanover, ownership made a meaningful investment in the asset, and the leasing activity we’ve seen reflects both the quality of those improvements and the continued strength of the Lower Tollway submarket.”
Following the recent leasing success at One Hanover, New York Life Investment Management has elected to bring the building to the market for sale. The capital markets team at Newmark has been hired to solicit interest from office investors.
Stream Senior Vice Presidents Marissa Parkin and Chase Lopez oversee leasing on behalf of ownership.
