Change of existing materials in a conservation area

We were granted planning permission on a residential apartment scheme to allow the client to change their existing timber windows for upvc, whilst in a conservation area. The client was actively seeking to change the windows to uPVC, for better insulation and maintenance reasons, however due to the local nature of the conservation area they needed planning permission to allow them to do so. We were commissioned to conduct a site survey and drew the plans and elevations which lead to granted permission.
