St. Pancras backs bogs – The Composer’s Cabin at RHS Chelsea Flower Show 2026

London St. Pancras Highspeed is sponsoring The Composer’s Cabin, by award-winning garden designer Martha Krempel, at the RHS Chelsea Flower Show 2026 to spotlight the importance of peatland conservation and sustainable gardening.

The Composer’s Cabin combines horticulture, music and environmental storytelling to create an immersive visitor experience inspired by the beauty and ecological significance of peatlands. Following its debut at this years’ RHS Chelsea Flower Show, an adapted version of the garden will travel to St. Pancras International, bringing the message of peat-free gardening and environmental stewardship to millions of travellers.

Supporting sustainability at RHS Chelsea Flower Show 2026

As the world’s most famous flower show officially goes peat-free, we’re supporting important conversations about sustainability, biodiversity and climate awareness.

Located within the Houseplant Studios area at the RHS Chelsea Flower Show, The Composer’s Cabin explores the hidden beauty and impact of peatlands through immersive planting, natural textures and sound. Visitors will be invited to step into the garden, engage with the landscape and reflect on the role peatlands play in protecting the environment.

The design also celebrates our long-standing connection with music and culture through the inclusion of a Steinway Spirio self-playing piano, creating opportunities for reflection and spontaneous performance throughout the show.

Bringing The Composer’s Cabin to St. Pancras International

Visitors can experience The Composer’s Cabin at the RHS Chelsea Flower Show 2026 from 19 – 23 May 2026 within the Houseplant Studios area sponsored by Malvern Garden Buildings.

From 1 June 2026, an adapted version of the garden will then be displayed at St. Pancras International, giving passengers and visitors alike the chance to experience the garden beyond the show.

Inspired by peatlands and peat-free gardening, the space encourages visitors to pause, explore and spend time with the garden as part of their journey through the station.

Reusing the garden and planting after the show also supports the RHS’s wider sustainability approach, helping the installation and important message it carries to reach new audiences beyond Chelsea.

Why do Peatlands matter?

Peatlands are among the planet’s most important natural carbon stores, consuming more carbon than all the world’s forests combined, despite covering only a small proportion of the Earth’s surface.

However, many UK peatlands are currently damaged, releasing stored carbon back into the atmosphere and contributing to climate change. Protecting and restoring peatlands plays an important role in regenerating this carbon ecosystem, and also supports biodiversity, flood mitigation and the preservation of important ecological history.

Through The Composer’s Cabin, we hope to encourage greater awareness of peat-free gardening and the simple everyday choices that can help protect these vital ecosystems.

Supporting peatland conservation is part of London St. Pancras Highspeed’s wider sustainability strategy and long-term environmental commitments.

Sam Sage, Sustainability and Environmental Manager for London St. Pancras Highspeed, said: “Sponsoring The Composer’s Cabin reflects our focus on supporting sustainability issues that have real, practical relevance to people’s everyday lives. The move towards peat-free gardening is an important step, and raising awareness of peatlands is a key part of that. This isn’t the first time we’ve brought peatlands into the station, and that’s deliberate – they’re hugely important but often overlooked, so continuing to raise their profile really matters. As the UK’s only high-speed rail link to mainland Europe, we see greener travel and environmental stewardship as part of the same story. Through installations like this, we’re using the station as a platform to bring those messages to a wider audience. We’re looking forward to passengers experiencing The Composer’s Cabin and engaging with the story behind it as they travel”.
