Founded in 1926 by Cecil Pell, the firm later partnered with Wilem Frischmann to become a multi‑disciplinary consultancy.
Headquartered in London, it has expanded globally with offices across the UK, Middle East, India, Turkey, and Romania.
It architects bold solutions for iconic structures—from the Centre Point tower to Liverpool One and Oxford’s new Bodleian Library.
The firm delivers across sectors including buildings, transport infrastructure, water systems, power networks, and environmental processes.
It has pioneered “firsts” in engineering, notably the tallest building in Europe and the UK’s first PFI road.
After a 2015 stake acquisition by German foundation RAG‑Stiftung, it gained a stable, long‑term ownership structure.
Subsidiaries like Frischmann Prabhu and Conseco extend its influence in Asia‑Pacific and the Middle East.
