Granular Chelsea
The Asthma and Lung UK Breathing Space Garden

Designed by
Angus Thompson

Built by
Dan Flynn

Sponsored by
Project Giving Back

Follow our journey to create a Main Avenue garden for the RHS Chelsea Flower Show 2026. A serene woodland-edge garden designed as a restorative ‘breathing space’ for people living with lung conditions, featuring accessible paths, therapeutic planting, and a tranquil platform for breath-focused practices.

 

“Designing for Chelsea for Asthma and Lung UK and with the Rotherham relocation and rebuild gave us the opportunity to step outside residential design constraints. This is a hugely personal project for myself and the design team and my wife Kate works in supportive and palliative care with people with lung conditions.” 
— Angus Thompson

Final day at Chelsea ‘26

Thursday of show week brought some very special visitors to our garden. We hosted an after hours event as an opportunity to thank all the people involved in the Breathing space garden. From metal workers to biochar producers; structural engineers to concrete producers; contractors to plant helpers, family and friends the list goes on.

The Planting Team

Our planting team are nearing completion of the Breathing Space garden ahead of assessment and judging over the weekend … and what a team! Working with great specialists has been a theme running through this whole project, and the planting is no different.

The Humble Path

Using the same material in different ways has always appealed to me. Be it different unit sizes or textured finishes, it can help create a unified whole, whilst adding interest and detail to a design.

Artist

This was a new one on me. An artist who works - in amongst other things - in restoring stone boulders to their rightful beauty.

Construction Team

You lose all sense of time when you're immersed in the mad dash that is Chelsea. Barely six days in and most of the major hard landscaping is already in place — no small feat given the scale of what's here.

Charred Boundary

Our first task on site was to construct  our boundary. Made from sustainably sourced charred timber, this will be re-used at our relocation site at Rotherham Breathing Space to form a new potting shed/tea hut.

Structural Engineering

One of the joys of a project like the Chelsea Flower Show is the chance to collaborate with a true mix of specialists, each bringing their craft to a wider team that turns a garden from idea into built reality.

The Boulders

And so to Cadeby quarry in Yorkshire; a quarry close to our final Rotherham garden rebuild with a view to sourcing 3 or 4 feature sandstones to embody the gnarled ‘existing landscape’ narrative of our Chelsea garden. Measuring over 2m in some cases, these pieces have an aged patina to them. In their raw state they exhibit strong red/ lilac hints which soften with age.

Breathe

Behind our Breathing Space garden for Asthma + Lung UK sits a body of scientific research and clinical practice showing that for many people with lung conditions, “just breathing” is anything but simple. From childhood asthma to later-life lung and heart disease, breathlessness can bring tension, anxiety and isolation, constricting people’s ability to thrive.
