Randle Siddeley has always had a strong eye for design – having grown up with the influence of his prominent interior designer father, John Siddeley – but his focus has always been directed towards the outdoors. As Randle explains, ‘The beauty of garden design is that, unlike interior design, a garden is always evolving. Rooms remain static while gardens are forever changing.’

He established his landscape design business over 40 years ago, and it thrives today with a team of 80 landscape architects, garden designers, landscapers and horticulturalists.

Though the company aesthetic could be described as classic but contemporary (following the golden rules, but with a nod to progressive design), Randle says he would never impose the company’s signature style on a garden. So many other factors come into play – in particular the individual tastes of the clients and, of course, the character of the property and its local area.

From re-contouring the mountain tops on a Canadian estate of tens of thousands of acres to closing half of London’s Holland Park in order to crane in mature trees, Randle Siddeley has always gone the extra mile to achieve the desired result. The company works with top craftspeople and artists to deliver impeccable finishes – especially crucial when designing and constructing a new town garden. Akin to fitting out a yacht, says Randle, this can require anything from bespoke joinery for outdoor kitchens, pergolas and trelliswork to the most intricate of metalwork for railings, and stone masonry for paving, cladding and copings.

This is not to say that Randle Siddeley will only take on large-scale projects. The business finds equal satisfaction in remodelling roof terraces, courtyards and tricky lightwells. The smallest improvements can have the most dramatic impact.

Furthermore, Randle Siddeley also offers a turn-key construction service, as well as working with other landscape architects. In addition, there is a dedicated maintenance division, which is able to tend the gardens for many years after their completion, ensuring that each garden always looks like it has only just been finished. In the case of a new garden, skilled horticulturalists ensure that the planting appears established, as if it has been there forever.

It is this attention to detail and careful sourcing that has secured these landscape architects work at stately homes across Britain, and at some of the most prestigious London addresses.

At any one time, Randle Siddeley’s client list might include heads of state, royalty and those who feature high on the annual rich lists. In some areas of London and Surrey, the company’s green-fingered influence is so prevalent that it has almost landscaped whole streets – though no one at Randle Siddeley would ever be so indiscreet as to let slip which ones.

With their passion for design and ‘nothing is impossible’ attitude, Randle Siddeley and his team have garnered a loyal following for over 40 years, one that will see the company continue to develop and deliver its clients’ outdoor aspirations for many years to come.
