Global launch of Zoffany x Michael S. Smith Indoor Outdoor Fabrics Collection

Sanderson Design Group PLC (AIM: SDG), the luxury interior design and furnishings group, announces the global launch of its Zoffany x Michael S. Smith Indoor Outdoor Fabrics collection. This is an innovative collaboration with Michael S. Smith, the celebrated American interior designer renowned for his timeless aesthetic and work on prestigious projects including the White House during the Obama administration.

The Zoffany x Michael S. Smith Indoor Outdoor Fabrics collection introduces 55 brand-new designs which Michael has hand-selected from Zoffany's extensive archives. Fabrics are printed to last and woven from performance-led materials which have been specially selected to so they can be used in both indoor and outdoor schemes.

The collaboration addresses a gap in the market identified by Zoffany and Michael, combining technical innovation with the aesthetic appeal of vintage fabrics. The fabrics, which will be launched in May 2026, will be available through the Company's global distribution network.

This collection reinforces Zoffany's positioning as a luxury, interior designer-led brand while supporting continued growth in key geographies globally, particularly in North America.

Lisa Montague, Chief Executive Officer of Sanderson Design Group, said: "We are thrilled to collaborate with Michael S. Smith on this collection. Michael's exceptional eye for design has resulted in a collection that redefines outdoor decor. We are confident this collection will set a new standard for indoor-outdoor living and look forward to its success in the global market."

Michael S. Smith commented: "This collection combines two things that I love: technical design and the ability to print indoor and outdoor fabric in a way that recalls vintage fabric, has a sense of history to it, but also endures. Coordination is everything. In interiors, you want an aesthetic that's grounded and is reflective of the surroundings. The palette was important. We used colours that sit beautifully inside and look beautiful in outdoor light, anywhere in the world."
