In September 2018 a Level II historic building record was made of an early 20th century mansion house on the northern periphery of Kettering town, Northamptonshire, prior to its conversion of the building to residential care apartments. The historic significance of the building in relation to Kettering's industrial heritage was identified by the county council's Archaeological Advisor. Formerly known as Avenue House, the historic building originated as villa in the late 1890s, when it was purposefully-built in relative proximity to Kettering Furnaces, by the Kettering Coal and Iron Company, for the company's managing director and his family. Essentially, the historic account explores the raison d'être of the building's construction and its social-political context within late 19th and early 20th century Kettering; predominantly by means of primary sources. The report provides a comprehensive descriptive and illustrative account of the building in its present 'as found' state by means of photography and scaled elevations and plans. In addition, the main phases of the building's historic development are identified.
