What services do you provide?

Landscape Design, Construction and Maintenance

How would you describe your style?

"Our design style is most aptly articulated as 'classic, yet contemporary'. We apply all of the golden rules of garden design but execute them with a modern twist and a nod to the heritage of the locale, building or project. In this way, our designs are clearly up-to-date, but we like to feel that they are timeless as well."

"Our portfolio of images demonstrates the variety of gardens and spaces that Randle Siddeley will go the extra mile to achieve the desired result. Roof terraces, courtyards, town gardens, country estates, public spaces and even tricky lightwells are all projects that we pride ourselves on being able to deliver with meticulous design and attention to detail.  

As people who are passionate about the outdoors and the beauty of nature, it is a privilege to be able to help our clients to design their perfect garden spaces.  A garden is both an intensely personal project and often a very public one at the same time. Striking the balance between an attractive and a 'useable' space is the most satisfying challenge we face."
