The Mossop name has been continuously associated with the South Australian building industry since 1946 when Bert Mossop undertook general building work following his return from World War II.

In the 1950's he created a niche business building caravans for South Australian families who were increasingly looking for low-cost holidays to share with their young families.

The '60's credit squeeze put enormous pressure on Broadway Caravan construction business, but again he identified another niche and built a successful ceilings operation.

By the late 1970's his three sons, Ray, John, and Neil had served their apprenticeships in the building industry as carpenters and joiners and established their own careers in one of Adelaide's largest building companies.

In 1979 the brothers established Mossop Group Pty Ltd as a building/interior specialist and the family business has grown to become a significant South Australian based commercial construction and interiors company.

Mossop Construction + Interiors is based at 155 Port Road, Hindmarsh in the iconic Brompton Wesleyan Methodist Church originally constructed in 1875.
