Historical reports

Local authorities usually ask owners of listed structures to demonstrate a good understanding of their building before making any changes. This is a reasonable, conservative approach which minimises the risk of losing architecturally significant or historically important fabric.

Can you be sure that the roof is not medieval? That those stained glass windows were designed by Powells? That the nineteenth century extension is worthy of restoration? An investigation of historic sources usually provides objective proof of age or evidence of previous alterations. It can also provide comparative evidence about the rarity value of a building type or historic feature.

A good historical report should chart the early history of the building, provide a comprehensive account of its development and subsequent alterations, and assess its significance using comparative examples and primary and secondary evidence.
