Landscaping & Landscaping Design
![]()
Randle Siddeley is behind many prestigious and widely renowned commercial, leisure, and private landscaping projects in America, Europe, Africa, the Middle East and the Far East.
Over the last 36 years, he has led a team of internationally recognised landscape architects, spearheading a large number of assignments from award-winning public developments to the creation of private gardens for a host of celebrities, dignitaries and Heads of State.
Renowned for his distinctive, inspired approach to landscaping design, he is frequently called upon by industry leaders and the media for unique insight and expertise. Earlier this year, British publishing house Frances Lincoln released ‘Garden’, the critically acclaimed book showcasing a selection of Randle’s most exquisite designs.
Son of celebrated international interior designer John Siddeley, Randle has inherited his father’s creative genes as well as his title: The Lord Kenilworth. He is an Honorary Member of the British Institute of Interior Designers and a Member of the British Association of Landscape Industries.
A lifelong sustainability advocate, Randle used his tenure in the House of Lords to raise awareness on key environmental issues – long before such concerns became fashionable – and has also worked on several Private Members’ Bills to that effect. He is also a Founding Member of Sustain Worldwide – a not-for-profit, pioneering organisation that brings together and promotes global developers who are mindful of their impact on the environment and committed to enriching their local communities.
Randle founded his landscaping business in 1975 and now heads up two distinct companies: Randle Siddeley Associates (RSA) – which focuses on commercial, leisure and residential landscaping projects; and Siddeley Landscape Designs (SLD) – which provides architectural design and project management services for private commissions.
Randle Siddeley Associates is a registered practice with the Landscape Institute, operating throughout the United Kingdom and overseas, and are an Equal Opportunity Employer.
