St. Pancras backs bogs – RHS Chelsea Flower Show garden, The Composer’s Cabin

The Composer’s Cabin arrives at St. Pancras International

Visitors to St. Pancras International can now experience The Composer’s Cabin, an immersive garden installation inspired by the beauty and ecological importance of peatlands.

Created by award-winning garden designer Martha Krempel and Malvern Garden Buildings, The Composer’s Cabin first debuted at the RHS Chelsea Flower Show 2026, where it spotlighted the importance of peatland conservation, peat-free gardening and sustainable horticulture. Following its appearance at Chelsea, an adapted version of the garden has been reimagined for St. Pancras International, bringing its environmental message to the millions of passengers and visitors who pass through the station each year.

Bringing nature, music and peatlands to St. Pancras International

Through a combination of carefully considered planting, natural materials and musical elements, The Composer’s Cabin creates a distinctive space for reflection and discovery.

At the heart of the installation is a wood-clad cabin filled with lush houseplants, creating a calm and intimate retreat within one of Europe’s busiest transport hubs. Surrounding planting draws inspiration from peatland and bog environments, featuring mosses, grasses and heathland species that reflect these important landscapes.

Visitors are invited to pause during their journey, explore the space and reflect on the relationship between creativity, nature and the environments that inspire both. The installation also celebrates London St. Pancras Highspeed’s long-standing connection with music through the inclusion of a Steinway Spirio self-playing piano, creating moments of reflection and spontaneous performance throughout the day.

From RHS Chelsea Flower Show to St. Pancras International

The Composer’s Cabin was originally created for the RHS Chelsea Flower Show 2026, where London St. Pancras Highspeed sponsored the installation as part of its commitment to sustainability and environmental awareness.

The garden was showcased within the Malvern Garden Buildings Houseplant Studios area and aligned with the RHS’s landmark move to a peat-free Chelsea Flower Show. Through immersive planting, natural materials and sound, the garden encouraged visitors to explore the hidden beauty and environmental significance of peatlands.

Its relocation to St. Pancras International allows the installation and its message to reach a wider audience beyond Chelsea, while supporting the reuse of planting and materials in line with our sustainability objectives.

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”.
