Planning assessments

The development consists of the demolition of the existing buildings to construct a 12-storey mixed use building comprising of commercial kitchens and public spaces at lower ground/ground floor levels to contain commercial and retail units alongside a food hall.

Herrington Consulting were requested to undertake a Daylight and Sunlight Assessment Report for the impact on neighbouring properties alongside the impact on recently consented schemes. We also undertook an initial transient overshadowing assessment and façade analysis.

The initial results indicated that majority of the neighbouring properties were compliant with the BRE criteria, but there were some properties experiencing reductions beyond the BRE thresholds. Consequently, we assessed the scheme against alternative targets using a previously approved scheme from 2021 on the development site as a baseline.

Concerns were also raised regarding the impact to a neighbouring scheme that had recently obtained outline planning and therefore did not have confirmed window and room layouts. We therefore suggested undertaking a façade analysis.
