72-80 Leather Lane is within the Hatton Garden Conservation Area, a place that represents a significant example of planning in the old City of London. The area was established in the 13th century by the Ely estate and continually expanded through to the mid-19th century, leaving a legacy of jewellery shops, warehouses, old brewing works and churches to mark its distinctive character. Our desk based and site work assessed the significance of this building to the Conservation Area. 

We identified ways in which the local historical context and the rise of  of an industrial quarter based on the development of variously sized buildings is a relevant factor in design. We carefully evaluated the impact of the proposals on the setting of adjacent designated assets. Our report stated that the proposed one storey extension responded well to the architectural integrity of surrounding buildings at roof level. Due to its subtlety in scale and appearance, it blended well with the interesting skyline started at the Prudential Assurance building at the southern end of the street and ending at the Bourne Estate on the north side.
