Three decades, one location – global consultancy strengthens Oxfordshire presence
Milton Park has revealed Tetra Tech, a global consultancy and engineering firm, has relocated one of its primary UK client hubs into a 9,500 sq. ft space on 101 Park Drive.
As one of Milton Park’s longest-standing occupiers, the move follows Tetra Tech’s 2023 acquisition of RPS, a consultancy founded in 1970, which has a 30-year history at the Park dating back to 1995.
Accommodating 120 high end consulting and engineering service professionals Leading with Science® to solve our clients’ complex problems, the fit-out of the new Grade A workspace is designed to deliver greater collaboration between teams, with spaces for hot desking, co-working and meeting facilities.
With 30,000 employees, Tetra Tech is a global leader in water, environment and sustainable infrastructure, providing high-end consulting and engineering services for projects worldwide.
Joe Ellis, Managing Director for Planning at RPS, A Tetra Tech Company, said: “Following RPS’ acquisition, 2025 is shaping up to be a really exciting year for our team based at Milton Park.
“You don’t often see 30-year relationships in real estate, however, with high-spec amenities in our new space, the move to 101 Park Drive highlights our continued investment in the region and long-standing relationship with the Milton Park team.
“Our teams are ideally situated to benefit from the government’s plans for growth, with our new client hub offering a welcoming environment for all who visit.”
Philip Campbell, Commercial Director at MEPC Milton Park, said: “At Milton Park, we take a long-term view to giving our occupiers flexible space to grow, as we’ve seen throughout the 30-year relationship with RPS a Tetra Tech Company.
“Tetra Tech’s renewed commitment demonstrates the Park’s ability to meet the needs of dynamic, forward-thinking organisations, who benefit from our single-ownership and ten-day simplified planning model. We’re delighted to support the team in the next phase of their impressive journey.”
