March 18, 2019

Washington – Transwestern today announced it has completed a lease negotiation for 11,629 square feet at 1899 L Street in the heart of Washington, D.C.’s Central Business District. Transwestern Executive Vice Presidents Pete Prominski and George Vogelei represented the landlord in this transaction that brings building occupancy to 91%. Cushman & Wakefield’s Malcolm Marshall represented the tenant.

“This building offers a new state-of-the-art chilled beam HVAC system and first-class property management in a fantastic location,” said Vogelei. The long-term institutional owner of the building provides onsite property management, a tenant-only conference center, and new mechanical systems and restrooms.  The building has easy access to Metro and offers abundant dining and retail amenities nearby.  An Energy Star LEED Gold building, it is also equipped with a secured bike room.    

“This is exactly what the tenant was looking for,” said Prominski. “Designed for them, with easy access to the conference and fitness centers and other amenities, their Washington home is a bonus for employees, as well.”

The 10th floor in the building, 12,640 square feet, recently became available and is an excellent opportunity for a new tenant looking for a straightforward deal structure, excellent amenities, and flexible lease terms.
