In their words

“Founded in 2009 as Polisano Leventhal Partners by Lee Polisano (American, ex-KPF) and David Leventhal, PLP Architecture grew out of three decades of prior collaboration on major international commercial projects.”

Founded in 2009 as Polisano Leventhal Partners by Lee Polisano (American, ex-KPF) and David Leventhal, PLP Architecture grew out of three decades of prior collaboration on major international commercial projects. The studio operates with the assurance of a long-established practice while maintaining a culture of curiosity and continuous research.

In 2015 PLP Labs was launched as an integrated research and strategy arm, examining emerging technologies, human behaviour and environmental challenges and translating insight into practical guidance for client projects. Today PLP runs permanent studios in London, Singapore and Tokyo, with a new Partner announced in Saudi Arabia in February 2026.

The London HQ at The White Chapel Building in Whitechapel was redesigned in 2025 as a working model for circular fit-out, with 92 per cent of materials reused or donated and 175.78 tonnes of CO2 diverted from landfill.

Co-founder David Leventhal stepped back from the board in July 2023, leaving Lee Polisano as sole active director and majority owner. The practice has been an AJ100 fixture for 14 consecutive years (2011-2024), peaking at rank 15 in 2018, with current rank 45 reflecting a post-pandemic compression in the commercial sector.
