# DLA Piper and Ascot Expand Footprints at Mitsui's Midtown Trophy Tower
DLA Piper and Ascot Insurance Group have committed to major lease expansions at 1251 Avenue of the Americas, the Mitsui Fudosan America-owned trophy office tower in Midtown Manhattan. The moves signal sustained corporate tenant appetite in a primary market tower despite broader office sector headwinds.
DLA Piper, the international law firm, expanded by 41,600 square feet on the entire 29th floor with an 8.5-year lease term. The expansion brings DLA Piper's total footprint at the building to 210,000 square feet. The firm now occupies multiple floors at the 50-story, 2.8-million-square-foot building between 47th and 48th Streets on Avenue of the Americas.
Ascot Insurance Group simultaneously inked a separate lease expansion at the same address, though specific square footage and lease terms remain undisclosed. Both tenants represent flight-to-quality decisions in favor of a Class A property in Manhattan's core business district.
The deals underscore the resilience of prime Manhattan office real estate. Trophy buildings with strong management, modern infrastructure, and prestigious tenant rosters continue to attract and retain long-term occupants even as secondary and tertiary office assets struggle with elevated vacancy and downward rent pressure. Mitsui Fudosan America owns and operates the property, maintaining the building's status as a destination for major corporate and professional services clients.
DLA Piper operates as one of the world's largest law firms by headcount and revenue. The firm's expansion reflects confidence in the firm's growth trajectory and its commitment to maintaining substantial New York presence. Law firms historically occupy multiple floors and full floors at premier Manhattan addresses to house practice groups, conference facilities, and partner offices. DLA Piper's move to occupy an entire floor signals the firm's expanding operations in Manhattan.
Ascot Insurance Group's parallel expansion suggests similar growth momentum. Insurance and financial services firms value Avenue of the Americas locations for client visibility and access to the Financial District and Midtown business ecosystem.
The 1251 Avenue of the Americas building houses major multinational tenants across financial services, law, consulting, and corporate headquarters functions. The property commands premium rents justified by its location, building systems, and tenant quality. Mitsui Fudosan America's ownership ensures professional management and capital investment in the asset's ongoing competitiveness.
These lease transactions offer landlords and institutional investors a data point on the trajectory of Class A Manhattan office. Trophy properties with institutional ownership, prime locations, and strong tenant profiles continue to capture demand from expanding or relocating tenants willing to pay premium rents. The deals suggest that the divergence between prime and secondary Manhattan office will persist, with capital and corporate tenants clustering around the best-positioned assets and locations.
For tenants considering Midtown office expansion, the DLA Piper and Ascot transactions represent available floor plates and expansion opportunities at one of Manhattan's most established trophy addresses. Landlords of secondary office stock face continued pressure to upgrade infrastructure, reduce operating costs, or accept lower rents to compete for tenant commitment.
