Part new-build, part refurbishment projects – ‘original building area’

In the Scope section of the technical manual, under the heading ‘Part new-build, part refurbishment projects’, limits are set out for the proportion of new-build floor area which can be assessed as part of a refurbishment scheme.
For the purposes of this guidance, ‘original building area’ refers to the area of the original building which is retained and refurbished as part of the assessment. It therefore excludes any part of the original building which is to be demolished or not part of the refurbishment scheme.

The aim of these limits is to ensure that the vast majority of theĀ developmentĀ is certified against the appropriate scheme, whilst allowing a degree of flexibility to account for such mixed-scope projects.
