Meet Julian

Garden designer, landscaper and plantsman with over 30 years experience.

I’ve spent more than three decades designing, building and planting gardens, combining creative ideas with the practical experience to know how they can actually be built.

For me, a successful garden starts with listening. I want to understand how you live, what you love and what you want your garden to become — then bring the design, landscaping, bespoke construction and planting together into one clear vision.

From first ideas to finished garden

Every garden starts with understanding what you want from the space. I’ll guide you through the process from the first conversation to the finished garden.

01
Initial Enquiry

Tell me about your garden and what you'd like to achieve. I'll review your enquiry personally and discuss the possibilities and next steps with you.

02
Design & Planning

Where detailed design, measurements or planning are required, I'll agree the scope and fee with you before work begins.

03
Build & Planting

Once everything is agreed, I'll bring your garden to life through skilled construction, careful planting and personal project management.
