AmTrustRE secures 5,754 s/f lease with GKV Architects at 360 Lexington Avenue

Manhattan, NY AmTrustRE has executed a 5,754 s/f lease at its premier boutique Midtown East office tower, 360 Lexington Ave., with longtime partner GKV Architects. The award-winning firm will occupy a portion of the 14^th floor.

“GKV Architects has been a trusted partner to AmTrustRE for over two decades, playing an integral role in shaping and elevating several of our largest assets and tenants,” said Jonathan Bennett, president of AmTrustRE. “Bringing the firm into 360 Lexington as a tenant reflects both the strength of that relationship and the continued momentum we’re seeing at this incredible property.”

AmTrustRE’s relationship with GKV Architects dates back more than 25 years, when the firm was first engaged to lead lobby renovations at 250 Bdwy., a 648,000 s/f, 31-story office tower in lower Manhattan. Building on that initial engagement, AmTrustRE has since partnered with GKV Architects across its portfolio, collectively contributing to more than 900,000 s/f of renovations. This includes extensive tenant buildouts for major companies such as WeWork and Rose & Rose, as well as numerous public-sector and government-related assignments that have been integral to advancing AmTrustRE’s relationships with the city and state of New York.

“GKV Architects has worked alongside AmTrustRE across a number of projects over the years, particularly in tenant spaces where their design expertise has been instrumental,” said Anne Holker,

Managing director of leasing and acquisitions at AmTrustRE. “We’re thrilled to now have them in-house at 360 Lexington and look forward to collaborating on future opportunities within our portfolio and the building.”

“We are thrilled to make our new home at 360 Lexington Avenue,” said Randy Gerner, a founding principal of the GKV office. “Nothing gives us more comfort than to know that we are housed in a building managed by such a caring landlord that doesn’t see us as ‘just another tenant,’ but rather a valued customer.”

360 Lexington Ave. is a 24-story, 268,000 s/f office building located within the Grand Central submarket. Centrally located in a bustling area, the property is steps from Grand Central Terminal, offering convenient access to New York City transit as well as commuter rail service to the greater New York area and Connecticut. Since acquiring the property in 2024, AmTrustRE has made improvements to the building and is in the final stages of a comprehensive transformation, which will include a redesigned lobby, modernized elevators, refreshed common areas, a new façade and an amenity center on the eighth floor featuring a lounge, pantry, bar and 20-plus-seat conference room.
