The London-based partners of Kohn Pedersen Fox (KPF) are looking to split from the firm's U.S. founders and have offered a proposal to buy full ownership of the U.K. business, the Financial Times reported on July 20.

The plan involves the U.K. partners swapping shares in return for full ownership of the U.K. business, along with an undisclosed sum. The London group is headed by Lee Polisano, president of KPF, and is working on projects with a total construction cost of $8 billion.

A spokesperson in KPF's New York City office declined comment on this report.
