Since joining Grimshaw in 1998 Jolyon has fulfilled several senior leadership roles, including a period as the practice’s Chief Executive from 2011 to 2015. His architectural portfolio is defined by its diversity, covering a broad range of sectors and scales.

His expertise in large-scale super-efficient enclosures is typified by his work on the Eden Project Biomes →. He has gone on to design schemes for Eden Project destinations in China and Australia, and is leading the concepts for the Heathrow Expansion →.

Jolyon has led the design of other large infrastructure projects through complex planning processes, including Stansted Airport’s expansion and Sizewell C – a new nuclear power station - both of which involve building design and master planning. His skills in these areas have led to his involvement in an urban extension north of Harlow and a number of regeneration master plans centred around railway infrastructure, including Euston’s HS2 project.

Jolyon’s building designs skilfully combine a wide range of influences. The efficiency of natural forms has inspired a number of buildings for Eden Project and NIRAH. His skill for carefully integrating projects with their contexts is evident in the Rolls-Royce Motor Cars Headquarters →, where the building forms part of a sustainable ‘ecosystem’. Jolyon’s enjoyment of collaboration is demonstrated by his work on The Core at Eden Project and The Laboratory at Dulwich College →, on which he collaborated with the sculptor Peter Randall-Page RA.

A passion for enquiry has led to Jolyon’s involvement in various research initiatives, ranging from the Aerogenerator → wind turbine, Grimshaw’s carbon-neutral Ecorainforest project, and his influential paper London: Hub City →.
