Sullivan & Cromwell is muscling into Houston, readying its first office in the city with temporary space in downtown’s Texas Tower and at least one partner set to land in the middle of Houston’s high‑octane legal scene. The Wall Street stalwart is the latest heavyweight to join the growing pack of national firms chasing energy, infrastructure and digital‑infrastructure deals, a sign that Houston is still a prime command center for lawyers handling energy and compute finance work.
As reported by the Houston Business Journal on Tuesday, the firm has started prepping space in Texas Tower for a full build‑out and intends the new outpost to serve regional clients. The report notes that this will be Sullivan & Cromwell’s first Houston office and that temporary quarters are already in place while the firm works through longer‑term plans.
Partner Hire And Temporary Space
In January, Bloomberg Law reported that Sullivan & Cromwell had hired Patrick Lingwall from Kirkland & Ellis and secured temporary offices in Texas Tower as it prepares a permanent Houston setup. Lingwall’s practice centers on acquisitions, divestitures and joint ventures in upstream and midstream energy, a résumé that lines up neatly with Houston’s client base. Bloomberg also noted that the firm had not publicly committed to how fast or how big it might build a local team.
Texas Tower: Where They’ll Land
Texas Tower is a 47‑story, roughly 1.23 million‑square‑foot Class‑A office tower at 845 Texas Ave that opened in late 2021, and its amenities and central location have already turned it into a magnet for national tenants, according to developer Hines. The building’s hospitality‑style lobby, outdoor terraces and flexible floor plates are designed to lure premium office users, which helps explain why multiple big firms and major tenants have clustered there. For Sullivan & Cromwell, the temporary space provides an immediate downtown foothold while the firm weighs how expansive a full build‑out should be.
Digital Infrastructure Strategy
Sullivan & Cromwell formalized a Digital Infrastructure Practice in December 2025 to handle energy project development, GPU and system financing, hyperscale data‑center deals and related joint ventures. “Digital infrastructure is among today’s most consequential business sectors,” the firm’s co‑chairs said in the announcement on S&C’s site, which frames markets like Houston as natural bases for that work. Sullivan & Cromwell described the initiative as a cross‑practice effort to provide integrated legal counsel on complex tech‑and‑energy transactions.
What This Means For The Market
According to Texas Lawbook, recent partner promotions and lateral moves have deepened Houston’s bench of transactional lawyers, a trend that has drawn national firms into the market in recent seasons. That growing pool of talent, combined with Houston’s steady stream of energy and infrastructure deals, helps explain why firms like Sullivan & Cromwell are planting flags in the city. The new office follows other national expansions aimed at keeping lawyers physically closer to regional clients, major projects and capital.
It remains unclear when Sullivan & Cromwell will finish a full build‑out in Texas Tower or whether it will quickly ramp up a large local headcount, Bloomberg Law reported. For now, the temporary downtown perch gives S&C a strategic Houston address as it courts regional clients and positions its digital‑infrastructure capabilities squarely in the market.
