Viaduct is an independent, Clerkenwell-based retailer of contemporary lighting and furniture. It was founded in 1989 by interior architect James Mair as a celebration of his love of contemporary design.

Viaduct was designed as, and continues to be, a destination for design lovers to find unique pieces for their home or projects. Each piece in the store is a celebration of timeless design, and celebrates quality, purity, visual lightness and fun.
