Mott MacDonald Leases Entire 25,372-Square-Foot Floor in New Empire State Building Deal
Empire State Realty Trust, Inc. , a prominent real estate investment trust known for its iconic and sustainable office properties, has announced the signing of a significant lease agreement with Mott MacDonald NY Inc., a global engineering, development, and management consultancy. The new lease encompasses an entire floor totaling 25,372 square feet at the legendary Empire State Building in Midtown Manhattan.
This new lease marks a strategic expansion for Mott MacDonald’s North American operations and signals the firm’s long-term commitment to maintaining a high-profile presence in New York City. In addition to the new full-floor lease, Mott MacDonald will continue to operate from its existing 18,434 square foot office at another ESRT property, 1400 Broadway. This dual-location approach within ESRT’s portfolio aligns with Mott MacDonald’s focus on flexibility, innovation, and a collaborative workplace culture.
A Strategic Move for Growth and Sustainability
Mott MacDonald has designated the Empire State Building as its new North American Headquarters. The decision reflects the company’s commitment to providing its employees with a world-class working environment that promotes innovation, sustainability, and collaboration.
“We look forward to welcoming colleagues to our new North America Headquarters at the Empire State Building, with its unmatched location, modern office space, and premier amenities,” stated Dean Radeloff, President and CEO of Mott MacDonald North America. “It supports our commitment to bringing people together in an environment that inspires, encourages collaboration, and advances our sustainability goals.”
The Empire State Building, one of the most recognized and celebrated architectural icons in the world, has undergone a massive transformation in recent years to become a model for sustainable and modern office spaces. The building is fully modernized and boasts exceptional indoor environmental quality, green building certifications, and high-performance design—all of which align with Mott MacDonald’s sustainability-driven values.
Anne Nolan, Regional Facilities and Real Estate Manager at Mott MacDonald North America, emphasized the high standard of service and professionalism offered by ESRT during the transaction process. “ESRT’s proactive and committed service provided a seamless experience as we sought a new high-profile space,” Nolan remarked. “Their understanding of our needs and dedication to quality made this an ideal match for our long-term vision.”
A Modernized Icon in the Heart of Midtown Manhattan
Owned and operated by Empire State Realty Trust, the Empire State Building is far more than a historic landmark—it is a forward-looking commercial hub that provides tenants with best-in-class workspaces and unparalleled amenities. It has been carefully modernized to support the needs of today’s companies while maintaining its architectural grandeur and historic significance.
Among its notable features, the Empire State Building offers more than 65,000 square feet of high-end amenities specifically designed to enhance the employee experience. These amenities include:
- Eight in-building dining options, ranging from casual cafés to fine dining.
- A tenant-exclusive fitness center with state-of-the-art equipment.
- A large, well-appointed conference center suitable for business meetings and corporate events.
- The Empire Lounge, which includes a 400-person all-hands meeting space, comfortable seating areas, private phone booths, a full-sized basketball/pickleball court, and two high-tech golf simulators known as “ESRTees.”
These offerings are complemented by robust transit connectivity, proximity to key transportation hubs including Penn Station and Grand Central Terminal, and panoramic city views that create an inspiring work environment.
The building is also a pioneer in sustainability practices, having achieved significant reductions in carbon emissions and energy consumption over the last decade. ESRT has implemented measures such as upgraded HVAC systems, improved insulation, LED lighting, and air purification technology—making the building one of the healthiest and most energy-efficient commercial spaces in New York City.
A Long-Term Partnership Strengthened
The lease signing further cements the longstanding relationship between Mott MacDonald and Empire State Realty Trust. Mott MacDonald’s decision to remain within the ESRT portfolio and expand into the Empire State Building reflects their satisfaction with ESRT’s property management, space quality, and commitment to sustainability.
“Mott MacDonald is familiar with our turn-key office spaces, top-tier amenities, sustainability leadership, and ESRT’s high-end service,” commented Thomas P. Durels, Executive Vice President of Real Estate at ESRT. “We are pleased that Mott MacDonald will continue their partnership with us and expand into the ‘World’s Most Famous Building.’ Their presence further reinforces the building’s status as a premier destination for forward-thinking companies.”
Durels noted that ESRT continues to attract leading firms seeking modern, flexible, and environmentally responsible office space in Manhattan’s most prestigious buildings. The Empire State Building remains a flagship property within the firm’s growing portfolio and an enduring symbol of innovation in the commercial real estate landscape.
Real Estate Professionals Behind the Deal
The lease transaction was facilitated by leading professionals from both sides. Mott MacDonald was represented by Sheena Gohil, Jack Senske, and Teresa DeLeo of Colliers International, a global real estate advisory firm known for its strategic tenant representation services.
On behalf of Empire State Realty Trust, the lease was negotiated by Shanae Ursini, along with a team from Newmark that included Scott J. Klau, Erik Harris, Neil Rubin, Brent Ozarowski, Zachary Weil, and Cole Gendels. The successful collaboration between these experienced brokerage teams ensured a smooth and mutually beneficial outcome for both landlord and tenant.
As Mott MacDonald prepares to transition into its new headquarters, the company continues to reinforce its role as a leader in engineering and consultancy services throughout North America. The relocation and expansion not only support operational growth but also serve as a testament to the company’s commitment to workplace excellence and sustainability.
The move also underscores the enduring appeal of the Empire State Building as a magnet for top-tier tenants. With its blend of historical prestige, modern amenities, and eco-conscious design, the building offers a compelling proposition for companies looking to elevate their brand and enhance employee satisfaction in one of the most dynamic business districts in the world.
As the commercial real estate market evolves, this latest lease deal between Mott MacDonald and ESRT reflects a broader trend: companies are increasingly prioritizing quality of space, location, sustainability, and employee well-being in their office decisions. The Empire State Building, with its unmatched combination of legacy and innovation, continues to meet and exceed these evolving demands.
