Millboard at RHS Chelsea Flower Show 2026

19–23 May 2026 | Royal Hospital Chelsea, London

RHS Chelsea Flower Show is the world’s most prestigious horticultural event, and this year Millboard has a presence across several design-led spaces at the showground. From Main Avenue to the food zone, visitors will be able to see our decking and cladding products in use across a range of beautiful outdoor settings.

At Millboard, we believe that the best outdoor spaces are born from genuine collaboration between the brands, designers and the people behind them. Chelsea is one of the finest stages for that, and this year we are proud to be working alongside some of the most respected names in the industry, including long-standing partners and some exciting new additions.

Garden House Design

We are delighted to be returning as product partner on the Garden House Design stand for the third consecutive year. Founded in 1996 by Rod and Debs Winrow, Garden House Design has built a well-earned reputation for creating exceptional outdoor living spaces, combining beautifully designed canopies, outdoor kitchens and considered garden environments. Their stand at Chelsea has consistently been one of the most admired commercial displays at the show, and 2026 promises to be their strongest year yet.

Located on Main Avenue at Stand 337, the stand features an expanded Millboard product footprint following the success of previous years.

Visitors to the stand will be able to see:

• Modello Linear and Enhanced Grain decking in Coppered Oak (including Bullnose and Square Edge Flexi)
• Shadow Line+ cladding in Coppered Oak, featured throughout additional areas of the design
• Shadow Line+ cladding in Burnt Cedar, used as a striking feature wall behind glass and set against a living mint wall

Cubic Outdoor Living – Garden House Design Stand

Also on the Garden House Design stand, we are excited to introduce a brand new partnership with Cubic Outdoor Living. Cubic are specialists in premium outdoor kitchens, bringing together exceptional craftsmanship and considered design to create outdoor cooking and entertaining spaces that are built to last. This year marks the first time Millboard and Cubic have come together at Chelsea, in a three-way collaboration with Garden House Design that feels like a natural fit for all three brands.

Millboard’s Board & Batten cladding in Burnt Cedar has been used to finish a Cubic outdoor kitchen on the stand, demonstrating how our cladding range performs in a functional, premium outdoor living context and proving its versatility beyond its normal usage.

BALI – British Association of Landscape Industries

Millboard is a proud member of BALI, the British Association of Landscape Industries and the UK’s leading trade body for professional landscapers and grounds care specialists. BALI exists to raise standards across the industry, and that mission aligns closely with our own. As a manufacturer, we recognise that the quality of our products is only part of the story; the skill and expertise of the landscapers, designers and installers who specify and fit them is what ultimately brings an outdoor space to life. BALI membership connects us to that community in a meaningful way, through shared standards, industry events and a collective ambition to raise the bar across the sector.

Supporting professional landscaping at Chelsea

Our collaboration at Chelsea is one expression of that relationship, but the partnership runs throughout the year. Whether through CPD opportunities, trade support or simply being part of conversations that shape the future of professional landscaping in the UK, Millboard is committed to being an active and supportive presence within the BALI network.

The 2026 BALI stand has been designed by Matt Evans of The Garden Room Living & Landscape Studio and installed by Frosts Landscapes. Matt is no stranger to Millboard, having previously specified our products on The Beacon Garden at BBC Gardeners’ World Live, so when he came on board to design the BALI stand at Chelsea this year, it felt like a natural next step in a relationship built on genuine trust in the product.

The contemporary design features a 2x3m Morvelle louvred pergola in Harvest Ochre, a Sky Garden living wall, Ca Pietra hexagonal cotto tiling, Wychwood Limestone edging stone and Furnitubes planters and seating throughout.

The stand showcases our recently launched Shadow Line+ in Ashwood, a colour that Matt was immediately drawn to. His enthusiasm for both the product and the Ashwood colourway was clear from the outset, and its warm, natural tone has informed the overall aesthetic direction of the stand design.

Shadow Line+ in Ashwood takes centre stage on the BALI stand

Shadow Line+ in Ashwood clads all boundary and feature walls, running vertically with reveal boards and corner trims. A crittall-style mirror window, framed within a Millboard and stud surround, adds a considered finishing detail to the rear wall. It is a compelling demonstration of how Millboard cladding can anchor a professional, award-standard landscape design.

Colicci – Food Zone

Millboard’s Enhanced Grain decking in Smoked Oak also features in the show’s food zone, where Colicci are creating a culinary experience for visitors. It is a fitting setting for a product that combines the natural warmth of timber aesthetics with the performance and durability demanded by busy, high-footfall environments.

the Glasshouse Collective at the Killik Barn

This year also sees The Glasshouse Collective make its debut at Chelsea, in partnership with Killik & Co. Killik are sponsoring a show garden designed by Baz Grainger of Landform, and for the first time are also taking their own trade stand at the show, known as the Killik Barn, where The Glasshouse Collective will be exhibiting throughout the week.

As a partner of The Glasshouse Collective, we are delighted to see them represented at Chelsea for the first time. The Collective will be championing the full breadth of its membership and promoting Millboard throughout the event.

Spacelift – AI-Assisted Garden Design

Millboard is also delighted to have a presence within the Spacelift debut at Chelsea 2026. Co-founded by award-winning landscape designer Matt Keightley, Spacelift is an AI-powered garden design platform making its public debut at the show across three full-scale gardens. Millboard’s Board & Batten+ cladding in Burnt Cedar features within the installation, a natural choice for designs that balance warmth and character with lasting outdoor performance.

About RHS Chelsea 2026

The show runs from Tuesday 19 to Saturday 23 May 2026 at the Royal Hospital Chelsea, with press day on Monday 18 May. RHS members have exclusive access on Tuesday and Wednesday, with the show opening to the general public from Thursday 21 May.

2026 Show Gardens

Show gardens remain the centrepiece of Chelsea, and 2026 looks set to be a particularly strong year. The Saatchi Gallery returns with a garden created in collaboration with kinetic artist Lucy Gregory and designer Naomi Ferrett-Cohen. Gregory’s sculptures, inspired by Matisse’s The Dance, respond to movement and invite visitors to interact with the space, bringing a compelling contemporary art dimension to the showground.

Project Giving Back marks its final year at Chelsea with a Feature Garden by James Basson of Scape Design. Drawing on the dramatic ochre landscape of Roussillon in Provence, the design is a fitting tribute to five years of funding charity-led gardens, many of which have since found permanent homes in communities across the UK.

The King’s Foundation Curious Garden, designed by Frances Tophill and championed by King Charles III, Sir David Beckham and Alan Titchmarsh, aims to inspire a new generation of gardeners. At its heart is an oak building representing a museum of curiosities, surrounded by seven raised beds (a nod to Beckham’s iconic number 7), alongside delphiniums, cut flower beds and planting that celebrates biodiversity. David Austin Roses is also expected to unveil a new rose named in Sir David’s honour at the show.

On Main Avenue, the Lady Garden Foundation’s Silent No More garden, designed by Darren Hawkes, carries an important message about women’s health advocacy.

Inside the Great Pavilion

Inside the Great Pavilion, specialist growers from across the UK and beyond return with botanical displays and rare plant collections. GreenSTEM returns with displays exploring biodiversity, climate-resilient planting and horticultural research, and visitors can view shortlisted entries for the RHS Chelsea Sustainable Excellence Awards, recognising exhibitors taking a more responsible approach to materials and production.

Inspiration for all

Whether you are visiting as a homeowner looking for outdoor living inspiration or a trade professional keeping pace with the latest in landscape design, there is plenty to see beyond our partner stands.
