Interior Design Magazine features Creative Director Rebecca Kelly in its “Ask the Designer” series, exploring her go-to surface materials for creating considered, cohesive indoor and outdoor spaces.

Interior Designer is the UK’s longest-running trade title for professional interior designers, and each issue includes “Ask the Designer,” a regular feature in which the magazine puts a single question to a handful of leading names in the industry.

The September 2026 issue poses the question of which surface materials designers turn to when creating a seamless indoor-outdoor space.

Four designers offer their perspectives: Rebecca Kelly of Jasper Sanders + Partners, Eugenio Laponte of Eutopiarch, Katharine Pooley of her eponymous studio, and Juliette Byrne.

Across the four responses, a clear consensus emerges: successful indoor-outdoor spaces depend on materials that can perform in both settings without breaking visual continuity, whether that’s porcelain, natural stone, timber or concrete. Several designers point to the way a single material, used consistently across a threshold, can dissolve the boundary between architecture and landscape altogether.

Rebecca’s contribution centres on restraint and continuity.
