Jen DonnellyGarden Design

About

A second career, and a much better one.

My name is Jen Donnelly, and I design gardens from home in Chalfont St Peter. Before this I spent more than twenty years in strategy, consulting and customer insight, with a long stretch of work on diversity and mental health along the way. It was a good career. It was not this one.

I retrained properly rather than drifting into it, taking the diploma at the London College of Garden Design and graduating with Distinction. What I brought with me from the first career turns out to matter more than I expected: listening to what someone actually needs rather than what they first ask for, structuring a project so nobody is surprised by a cost, and writing things down clearly enough that everyone is building the same garden.

The practice is just me. That is a deliberate choice, not a stage on the way to something bigger. The person who walks your garden at the consultation is the person drawing the layout, choosing every plant on the planting plan, reading the contractors' quotes with you and standing on site when it goes in. No handovers, no juniors, nothing lost in translation.

What I care about is whether a garden gets used. Gardens that look immaculate and sit empty are a failure of design, not of the owner. So I start from how you want to spend time out there — eating, talking, sitting quietly, watching children or watching bees — and design backwards from that. I call it designing social spaces, and it is the thread through everything, from a suburban back garden to a hospital courtyard.

Credentials

Two things worth checking.

Garden design is an unregulated profession — anyone can print a card. These are the two credentials I have, and both can be verified independently.

RHS Chelsea Flower Show 2025 — Gold Medal

For the Room to Breathe Hospital Garden for the TSA, in the Container Gardens category, co-designed with Catherine Gibbon.

London College of Garden Design — Diploma

Graduated with Distinction. The LCGD diploma is the full professional training in design, construction, planting design and practice — not a short course.

No trade body memberships or contractor certifications are claimed here, because I am a designer rather than a contractor — the building is done by landscape contractors carrying their own accreditations and insurance.

Where I work

Based in Chalfont St Peter, working across three counties.

Home is Chalfont St Peter, and most of my projects are within easy reach of it — Gerrards Cross, Chalfont St Giles, Amersham, Beaconsfield and the surrounding villages. I also work more widely across Buckinghamshire, Berkshire and Hertfordshire. If you're not sure whether you're in reach, just ask.

Jenny transformed our front and back gardens… The landscaping and planting is such high quality that it feels magazine worthy. And the driveway no longer floods!!

Jenny was fantastic from start to finish and really cared about the design of our garden, coming up with some great ideas, spending the time needed to make sure we were happy with the design before proceeding.

Great experience working with Jen, extremely thorough and very positive attitude! … Jen produced some amazing CAD type designs to help us decide the best approach and worked with our builders on site.
