historic building impact assessments

Historic Buildings Impact Assessments are used to inform decisions regarding any alterations to a historic building by examining the physical and visual impact of specific proposals on a listed building and where appropriate advising on measures of mitigation to minimise any adverse impacts.

TRIGPOINT Conservation & Planning has successfully undertaken a number of impact assessments covering a broad range of buildings and proposals. The assessment typically combines an understanding of the building’s history and chronological development with a detailed visual survey of the existing building, providing an understanding of its form, function and fabric and identifying features of particular architectural significance.

historic building impact assessments - case studies

		24 Castlegate, Newark (in association with Anthony Aspbury Associates) No. 24 Castlegate, Newark is a Grade II listed building. To support proposals to convert the property from offices to a restaurant along with internal alterations, the local planning authority asked for an historic building impact assessment to provide an understanding of the building and to assess the impact of the works. The impact assessment prepared by TRIGPOINT Conservation & Planning traced the development of the existing buildings on the site and provided an analysis of the surviving layout and fabric of the building. It was clearly evident that these buildings had been altered in the past but the report was able to identify the most significant surviving features and to propose a strategy to implement the proposed change of use without adversely affecting these features. The report also identified those features that could be altered or removed without harm to the building’s character. The final impact assessment was submitted in support of the applications and planning permission and listed building consent were subsequently granted by Newark & Sherwood District Council.

		Constitution Hill, Birmingham No. 60-62 Constitution Hill, Birmingham is a Grade II listed building within the Jewellery Quarter Conservation Area. Having been used as a warehouse for a number of years, proposals were brought forward to convert the property to flats, a restaurant and offices. The impact assessment was able to trace the chronological development of the existing buildings on the site, identifying the original buildings that had been built in the early nineteenth century as offices and workshops from buildings added at the end of the nineteenth century when the building was in use as a foundry. The impact assessment was used to inform the proposed development and was able to show that the proposals offered a significant opportunity to secure an economically viable new use for the building without significantly harming its special architectural and historic interest.

		Albert Terrace, High Street, Loughborough The properties at Albert Terrace, whilst unlisted, represented a rare group of surviving Victorian residential courts that were once common in the centre of Loughborough. On receipt of proposals to convert the surviving buildings to four new residential units, the local planning authority asked for an historic building impact assessment to consider the impact of these changes on the existing buildings. The impact assessment traced the chronological development of the existing buildings on the site, but it was evident from the site visit that these buildings had been substantially altered with the loss of original fabric and details. The proposed development was therefore unlikely to cause any further damage to important historic fabric but it did offer an opportunity to restore the external appearance of these units and offer a viable long-term economic future to a group of buildings that were of some local historic interest and worthy of retention. historic interest and worthy of retention.
