DALLAS – September 15, 2025 – Stream Realty Partners, a national commercial real estate firm offering an integrated platform of services, has been awarded the 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, best-in-class amenities, and premier signage opportunities overlooking Klyde Warren Park. The building was redeveloped by Todd Interests, the acclaimed Dallas developer behind East Quarter and The National.
Stream Executive Vice President & Partner JJ Leonard, Senior Associate Patrick Cruz, and Associate Sam Bass will lead the leasing efforts for the office tower.
“The Sinclair embodies the very best of Dallas—innovative design, modern amenities, and unmatched location—and this mandate represents a rare opportunity for our team to reintroduce a landmark Dallas tower to a new generation of office tenants,” said Leonard. “While the property currently offers a unique, 430,000 square foot block of space, we are also planning to create bespoke, flexible, high-end spec suites to offer to smaller and mid-sized users as well. These advantages, when combined with a strong, creative ownership team, present a very unique offering for office users in the heart of the city.”
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, redefining what a mixed-use project in Dallas’s urban core can be.
Office tenants at The Sinclair will benefit from incredible skyline views, a contiguous 16-floor block of space, and three unique patio terraces on every floor. Amenities include ample parking, a state-of-the-art 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. With a Walk Score of 94, the property offers immediate access to hotels, restaurants, transit, and cultural attractions.
