An Inspector appointed by the Welsh Ministers has dismissed an appeal on a retrospective application for external insulation on an unlisted cottage on the basis that ‘the installation of the insulation has significantly adversely affected the distinctive appearance and architectural integrity of the terrace’.
The Inspector also noted that:
‘Photographs show that prior to the insulation being installed the appeal property had an exposed stonework wall finish and traditional window cills. These features would have contributed significantly to the building’s traditional vernacular character. In contrast, because of its thickness, it is now apparent that a non-traditional external wall treatment has been applied. As the traditional cills have either been removed or covered by the thickness of the insulation the vernacular appearance of the window openings has been lost. Whilst the cream colour does not look out of place, the self-coloured render is smooth and modern in appearance.’
The Inspector went on to observe:
‘Neighbours’ concerns about the effect of the insulation on the breathability of the traditional stone walls are supported to an extent by Welsh Office Circular 61/96: Planning and the Historic Environment: Historic Buildings and Conservation Areas, the Appendix to Annex D of which advises that non-porous coatings can form a barrier which prevents moisture trapped within walls from evaporating, leading to problems arising from damp. However, the performance and suitability of the particular system installed in this instance is a matter principally for the installer. It is therefore not a consideration that has influenced my decision.’
