About Us

We’re a team of designers with decades of experience, and a real passion for everything we do.

In 2000, Lumsden was invited to design the bookshop for the new Tate Modern, a remarkable project led by the Swiss firm Herzog & de Meuron, which converted the then-redundant Bankside Power Station into one of the most recognised art museums. Since then, we have been designing amazing spaces for museums and attractions worldwide, from MoMA NY to the Warner Bros. Harry Potter Studio Tour in Tokyo.

After 30 years’ working in the experience and retail design sector, in 2023, Callum Lumsden transitioned from his original role as a founder. A new structure and MBO have been led by Lumsden’s design director, James Dwyer, who becomes owner and Creative Director of the company.

James Dwyer, a founding member of the Lumsden team, has 16 years of experience in retail, hospitality, and exhibition projects. As Creative Director, he ensures compelling creative direction for clients’ target audiences. His blend of creative thinking and practical solutions is key to our success. In 2023, James became the sole owner of Lumsden following the founding members’ retirement.

Simon Clark co-founded Lumsden Design with Callum in 2010. He began his career in a family shopfitting business, expanding it significantly over 15 years.

Simon oversees business processes, prioritising client value while preserving design integrity.

Callum Lumsden, who led Lumsden until 2023, and his team excelled in innovative retail designs for museums, galleries, and visitor attractions worldwide. Specialising in retail strategy, interior architecture, and branding, he was committed to both experiential and commercial success. With a track record including Tate Modern, MoMA, and V&A, Callum brought authoritative insight to projects for worldwide clients.
