SNN114631 - Conversion of Stables Outbuilding to Domestic Annexe at Upton Mill House, Upton Lane, West Northamptonshire NN5 4UY: Historic Building Impact Assessment

The Assessment concerns the proposed conversion of a former late Victorian stables range and carriage house to a domestic dwelling. The brick-built range with contemporary enclosed stable yard is situated within the curtilage of Upton Mill, Northampton. The former mill, presently a private house, is a Grade II Listed Building located on the south-western periphery of Northampton town. The range of stabling outbuildings was a part of a working farm throughout the 20th century, specialising in livestock grazing and, as such, underwent various alterations to adapt to needs. The buildings have been redundant as farm units for many years. At least two major phases of alterations have been identified in the assessment, including the conversion of the carriage house to form extra stabling. Late 20th century renovations included re-roofing, replacement of doors and door frames and up-grading most of the original brick floors with concrete. The Assessment first looks at the historic context of the building and ascertains the chronological sequence of historical alterations. It then identifies the historic significance of different components of the building and, subsequently, considers the potential effects of the proposed alterations on that significance. The assessment has identified some aspects of the proposed internal and external alterations which may adversely affect significant components of the building’s historic fabric. These aspects will require design re-consideration or construction solutions in order to avoid or alleviate impact on the historic building. Essentially, the Assessment is impartial, analytical and interpretative, and follows an informed staged approach. It combines first-hand observations with historical research data in order to assess the significance of various facets of the heritage asset. Its aim is to identify any negative impacts on the heritage asset that may be caused by the proposals, in accord with national and local planning policies. This, in turn, will allow the local planning authority (LPA) to make informed decisions with regard to the planning proposals.
