Randle Siddeley
No space too small or too large for a beautiful garden

Randle began his professional life working for his father, interior designer John Siddeley. He quickly realised that designing a garden was very different to renovating a home. ‘With interior design, you can see fairly instantly whether a particular paint colour or piece of furniture works,’ says Randle. ‘But with gardens you have to wait months, years, to see the fruits of one’s aspirations. Rooms stay static but gardens are everchanging with Mother Nature very much in control.’


Just over 40 years ago, Randle Siddeley formed his landscape construction company, which quickly grew into a full-service landscape architecture practice with a contracting division offering a full turn-key service, from initial sketches to ongoing maintenance. Today he works globally with a team of 80 with offices in London, Hong Kong and New York, transforming everything from tiny backyards to vast fields into magical green oases. His designs are classic and timeless but contemporary, often excitingly innovative and always respectful of the heritage of their surroundings.

His philosophy remains rooted in a refusal to compromise, working with some of the most talented craftspeople in their fields to ensure every detail, from bespoke trelliswork to stonework, is finished to the highest standard. Randle’s firm belief is that any space, whatever size or scope, can be transformed. He is practical at all times, whether he is creating the perfect spot for a swimming pool or choosing plants that require little maintenance to survive and flourish.


Randle seeks out the best artisans and artists to provide eye-catching features and talking points. Specialist Andrew Moore made a decorative glass wall, renowned sculptor David Harber has provided beautiful water features and last summer Gaze Burvill created an extraordinary piece of garden furniture, the Meander Loveseat – a threeseater bench crafted from prime grade oak. With his focus ever on practicality as well as design, Randle might even supply an Ooni Koda portable gas-powered pizza oven. ‘I always love to see good, innovative design paired with functionality,’ he says.


Since the start of lockdown, the garden has become increasingly important as people have looked to it as a valuable extra room. ‘It has made people more appreciative of outdoor space than ever before’, says Randle. ‘It’s an extraordinary time to be in outdoor design.’ This year the team has been designing a garden in north London with a new swimming pool, working closely with the client to ‘bring the inside outside’ adding a generous dining and entertainment space, an outdoor kitchen, a snug, a fireplace and integrated heating so the space could be used year-round.

A future plan of Randle Siddeley is to embrace 3D design so that clients may see realistic CGI models of their future gardens and envision Randle’s signature transformation.

Randle considers his designs to be constantly evolving as he adapts to his clients’ changing needs. ‘As someone passionate about the beauty of nature, it is a privilege to help our clients design their perfect garden spaces,’ he says. ‘A garden is both an intensely personal project and very public. Creating a space that is both beautiful and usable is the most satisfying challenge we face.’
