Mott MacDonald moves North America headquarters to the Empire State Building

Relocation reflects continued investment in clients, communities, and talent across North America

We’re proud to announce we have relocated our North America headquarters to the iconic Empire State Building, marking a significant milestone in our continued growth and investment across the continent.

Located in the heart of Midtown Manhattan, the new office provides a modern, collaborative workplace that strengthens connections with clients, partners, and colleagues while supporting our continued growth in the region, including the New York Metropolitan area. The move reflects our long-term commitment to serving our buildings, federal and defense, energy, transportation, and water markets through integrated expertise and innovative solutions.

As one of the world's most recognizable landmarks, the Empire State Building represents ambition, innovation, and resilience, values that align closely with our purpose of creating the essential infrastructure needed for a more inclusive and resilient society.

To commemorate the occasion, our leaders joined Empire State Building representatives for a lighting ceremony. The tower was illuminated in the company's signature colors, highlighting the significance of the move and our company’s growing impact across the region. The celebration brought together colleagues from around the world to mark this new chapter for the business.

Mellanie Bennett-Monclova, New York City portfolio manager, said, "Relocating to the Empire State Building places us at the heart of one of the world's most dynamic business communities and creates an environment where our teams can collaborate, innovate, and continue delivering exceptional outcomes for our clients. For many of us, New York City is not only where we work but also where we live. Celebrating this moment with the Empire State Building illuminated in our colors is especially meaningful."

We have helped shape infrastructure across the New York metropolitan area for more than 80 years. Working alongside public and private sector clients throughout New York and New Jersey, our team has contributed to projects spanning transportation, water, aviation, energy, and underground infrastructure, helping communities connect, grow, and thrive. From our new location in the Empire State Building, we will continue to bring together global expertise and local insight to support the region’s evolving infrastructure needs and long-term resilience.

Dean Radeloff, executive board director and CEO and president, North America, said, "Our continued growth across North America is rooted in our commitment to our clients, our people, and the communities we serve. The Empire State Building provides a world-class workplace that supports collaboration, attracts top talent, and strengthens our ability to deliver complex projects for clients across the region. This move is a reflection of the momentum we've built and the opportunities that lie ahead."

The new office has been designed to encourage connection, collaboration, and flexibility, providing an environment that supports both high performance and wellbeing. The space reflects our ongoing commitment to fostering a culture where people can thrive and deliver their best for clients and communities.
