Where the area thresholds given in the Scope section of the manual are exceeded, but new-build areas are integral to and inseparable from the refurbishment, separate assessments or a bespoke RFO/NC assessment may not be appropriate.
This typically refers to new build areas scattered around the floor plans, as in the example, rather than horizontal or vertical extensions linked to a specific part of the existing building.
In such cases, please submit comprehensive plans, clearly identifying the new-build spaces, along with a description of the project, to BRE for review.
