Stream Realty Partners has been awarded office leasing, property management, and construction management for The Sinclair, a $300 million redevelopment in Downtown Dallas.  

Located at 401 N. Ervay St., The Sinclair is a 429,000-square-foot office tower that anchors a mixed-use project featuring 293 luxury multifamily units.

Stream’s JJ Leonard, Patrick Cruz, and  Sam Basswill lead the leasing efforts for the office tower.   

Originally completed in 1983 and designed by I.M. Pei & Partners, the tower—formerly Energy Plaza—served as offices for ARCO Oil & Gas, Oncor, and the FDIC. In 2022, Todd Interests embarked on a $300 million redevelopment of the largely vacant building alongside architect HKS and contractor Brasfield & Gorrie. The tower reopened in early 2024 as The Sinclair.  

Amenities include three patio terraces, a fitness center with a cold plunge, sauna and steam room, a tenant lounge and bar, extensive conference and training facilities, a golf simulator, and a landscaped garden courtyard lounge. Additionally, an on-site restaurant and coffee bar are planned for delivery in 2026.
