100% Design 2026 is a trade fair in London, United Kingdom.
100% Design is the UK's largest contemporary design trade show, held each September at Olympia London as an anchor of the London Design Festival. The 2026 edition, its 22nd, runs 21-24 September 2026 under the theme "Experience Design". Organised by Media 10, it presents national and international exhibitors across sections including Interiors, Workplace, Kitchens & Bathrooms, Design & Build and Emerging Brands, drawing more than 26,000 visitors over four days.
100% Design is a design-led trade show judged on presentation, so its stands lean toward the considered, high-finish end. Exhibitors present furniture, lighting, surfaces and interior products in curated settings with careful lighting and material palettes, because the audience of architects, designers and specifiers assesses on aesthetics and quality. The Emerging Brands section favours smaller, design-forward booths, while established exhibitors build more substantial branded environments; across both, finish and lighting carry the stand.
The show occupies Olympia London, a historic venue with its own architectural character and a mix of hall levels, so stand placement and how a build works within the space affect footfall and impression. Olympia's central London location eases access but constrains load-in through a compact urban site, and the venue's rules apply. Given the finish standards and the venue's characteristics, exhibitors confirm stand design and placement well ahead.
For companies exhibiting at 100% Design, a builder with London and Olympia experience is a genuine advantage: design-grade stands need specialist finishing and lighting, and local knowledge of the venue's logistics, urban load-in and approved contractors reduces risk during London Design Festival, one of the busiest design weeks in the calendar.
