The designer is one of 12 new Royal Designers for Industry to be recognised for their outstanding contribution to design and society at an award ceremony to be held at the Royal Society of Arts (RSA) in London today (14th November).
Also recognised this year is Andrew Grant, principal of Grant Associates for his pioneering work in sustainable and ecological landscape architecture.
They are only the second and third British landscape designers to receive the award since it was introduced in 1936. The first was Kim Wilkie in 2009.
On Friday landscape designer Pearson won the Grand Award, the highest accolade, at the inaugural Society of Garden Designers Awards for The Tokachi Millennium Forest, in Hokkaido, northern Japan.
Other notable projects in his career include the Althorp House, the Millennium Dome, Roppongi Hills and the London Maggie’s Centre, as well as a large number of private commissions in Britain and overseas.
The distinction Royal Designer for Industry (RDI) was established by the RSA in 1936 to enhance the status of designers in industry and to encourage a high standard of industrial design. It is widely regarded as the highest accolade for designers in the UK, given to practising designers who have shown sustained design excellence, work of aesthetic value and significant benefit to society.
The other recipients of this year's award include Brian Eno for his ground-breaking use of sound in technology and media and long term sustainable thinking, Mark Fisher for his influential contribution to production design and British popular culture, Mark Major for his innovative use of light to create positive public spaces.
RSA chief executive Matthew Taylor said: "The RSA has vigorously championed design excellence since its foundation when the design profession was in its infancy. We remain committed to encouraging and recognising outstanding designers who strive to make the world a better place. The work of these 12 fantastic practitioners has made a significant benefit to society and I’m delighted to welcome them to the faculty."
