Designed around life

Feel protected in the Subaru Cocoon Garden

RHS Hampton Court Palace Garden Festival

1 - 6 July 2025

A space to preserve and protect

The Subaru Cocoon Garden is a beautiful showcase for regenerative design. Centred around Britain’s temperate rainforest - which used to cover 20% of the land and is now just 1% - it shines a light on our need to preserve a delicate ecosystem and give back to nature.

In lieu of a traditional walled garden door, a reflective water threshold - a symbolic cleansing - leads into a cool, immersive landscape of texture and shadow

We are proud to support Mike McMahon and Jewlsy Matthews, of Mike McMahon Studio, in bringing this immersive experience to life at the prestigious RHS Hampton Court Palace Garden Festival.

The Subaru Cocoon captures the spirit of Britain’s temperate rainforests, blending naturalistic planting with a modern twist on the traditional walled garden.
At its heart is a sweeping curved jali wall - a perforated screen inspired by Indian architecture, reimagined here as a contemporary lattice that honours co-designer Jewlsy Mathews’ South Indian heritage. The wall filters dappled light, offers glimpses inward, and invites plants to spill through and beyond its patterned openings.

Made from 4,500 Kenoteq K-Briqs, an innovative brick composed of recycled construction waste and carrying just 5% of the embodied carbon of standard bricks, the wall reflects the garden’s commitment to sustainability. Its built-in cavities double as insect hotels, offering shelter for pollinators, while a planted trough above boosts biodiversity.

RHS Hampton Court Palace Subaru Cocoon Show Garden

Temperate Rainforest Sanctuary

A reflective water feature reimagines the traditional garden entrance, guiding visitors to an elevated walkway that invites new viewpoints. Plants weave through the wall’s openings, softening its structure and echoing the wild, layered beauty of a rainforest. A minimalist seating area, with furniture crafted by Mike and Jewlsy from recycled paper, offers a tranquil space for reflection. Throughout, a vibrant mix of flowering plants attracts pollinators and supports local wildlife, reinforcing the garden’s ecological harmony.
The garden will feature in the RHS Hampton Court Palace Garden Festival’s Show Garden category situated on the Main Avenue from 1st - 6th July 2025.
