A show garden in bloom at the Chelsea Flower Show

A flower show just became ground zero for the AI garden design fight

September 04, 2026

Most garden news does not come with a professional guild in open revolt. This one did.

At the 2026 RHS Chelsea Flower Show, award-winning designer Matt Keightley unveiled three full-size gardens designed with an AI app instead of a human working the plan by hand, according to Gardens Illustrated. The gardens themselves were real: a compact urban terrace, a restorative rural retreat, and a nature-led woodland garden. What they represent is the part that matters for the rest of us.

What the app actually does

Keightley built the app, called Spacelift, and used Chelsea to launch it. Here is how it works, per Gardens Illustrated's reporting:

You scan your outdoor space.
You describe what you want and what you can spend.
Within minutes, you get a photorealistic, buildable plan, plus planting recommendations, material suggestions, and shop-the-look links.
If you want more, the app connects you to a local tradesperson.

It already had 9,000 people on its waitlist before launch, according to the company, cited in Gardens Illustrated's coverage.

That is not a toy. It is a product built around a real gap: the cost of hiring a professional garden designer, which puts the service out of reach for a lot of households who would otherwise want one.

The designers are not laughing

The Society of Garden and Landscape Designers, the professional body representing UK garden and landscape designers, pushed back hard. Its chair, Andrew Duff, put the objection plainly: good garden design "is an art form based on creativity, working together and human connection," and technology "cannot replicate the insight, empathy and personal engagement that comes from working with a skilled garden designer," per Eastern Eye's reporting.

Individual designers were sharper. Yvonne Price, who has shown work at RHS Hampton Court, called Chelsea's decision to include the AI garden "a betrayal." Designer Nadine Mansfield asked, sarcastically, what time the job centre opens. Tom Massey, a Chelsea gold medal winner who has used AI himself for tracking soil and growth data, drew a clear line between that and full automated design: "I don't think many people would like the idea of robot designers."

All three are quoted via Eastern Eye's reporting, which attributes the remarks to The Guardian. That is a specific fear, not a vague one: a client who can get a photorealistic plan in minutes for an app subscription might simply stop calling a human.

The other side of the argument

Keightley's response is worth hearing straight, because it is not "AI is better." Told The Guardian, quoted via Eastern Eye: "We're used to using technology to design every part of our homes except our gardens. Spacelift changes that."

His pitch is about access, not superiority: people who cannot pay for a designer at all get a starting point they would not otherwise have.

Spacelift's head of partnerships, Alexandra Davison, went further, arguing the tool could help designers rather than replace them. A homeowner with a clearer plan and more realistic expectations, she argued, is an easier client to work with, not a lost one.

We are not going to tell you who is right. A working guild is defending a craft that took years to learn. A founder is betting access matters more than exclusivity. This fight will not stay in the UK flower show circuit: every paid garden service is a candidate for the same argument within a few years.

Bottom line

Chelsea 2026 featured the first AI-designed show gardens, built with an app called Spacelift, per Gardens Illustrated.
The UK's Society of Garden and Landscape Designers publicly objected, arguing technology cannot replace human insight and empathy, per Eastern Eye.
Spacelift's pitch is access for people priced out of hiring a designer, not a claim that it designs better, per the same Eastern Eye reporting.
A scanned photo and a budget number cannot know your yard's drainage, shade, or your real maintenance time, the gap a human designer still fills.
