50 Years, Three Generations
Founded in 1976 as Clark & Son, we've grown from a local building company into a principal contractor trusted with some of the region's most demanding projects. From transforming the historic 1926 Reptile House at London Zoo, to boarding house projects at St Albans High School for Girls and Berkhamsted School, residential development schemes, accessibility projects, heritage listed building and insurance works across London and the Home Counties.
The family name on the vans hasn't changed in fifty years.
