David Mellor (1930-2009), the renowned metalworker and designer, is responsible for some of the most iconic pieces of design that still surround us today. From traffic lights to post boxes, most of us will likely pass - often unknowingly - pieces of his work several times a week. It was at Park Lane, his house and studio in Sheffield, that he conceived many of these designs; indeed, all of his designs, limited editions and prototypes between 1960 and 1972 were created here.

This slightly smaller house is situated on a plot of land that was separated from the original house and workshop in the 1960s. It was designed by Mellor in collaboration with architect Patrick Guest on a one-acre plot of land previously given over to an orchard, and given to Mellor for free by one of his many neighbouring admirers. The land was quickly identified as the perfect location for a house, which was intended to house Mellor and his growing family as his burgeoning design business swelled to fill the original house and workshop.

The newer, smaller house feels like a natural continuation of the now Grade II-listed workshop, exhibiting many of the same approaches to materials, space and light. Formed largely of glass and timber, the house was inspired by space-saving mid-century Scandinavian homes which influenced much of Mellor's approach to interior design.

After his time at Park Lane, Mellor moved to Broom Hall - another live-work home - and then to the Round Building in Hathersage, designed by Hopkins Architects, which remains the HQ of his family-run design business.
