Internal alterations to include replacement of first floor rear sash windows, removal of modern block partitions and boiler to lower ground floor. Reinstatement of staircase link to lower ground floor. Repositioning of kitchen. Replacement of bathroom fittings and redecoration.
It is proposed to replace the existing single pane timber sash windows across the rear elevation with multi-pane sashes. The age of the existing windows has not been indicated as part of this application, but it can be assumed that these are not original to the building due to their fenestration type. BPT is therefore supportive of the principle to reinstate the traditional sash form and profile with heritage gain to the special architectural interest of a listed building and the group value of a Grade I terrace.
However, we strongly maintain that appropriate details and drawings should be supplied as part of this application to fully assess the suitability of the proposed interventions, including existing and proposed elevations, and proposed sections and details to ensure that an acceptable glazing bar profile and thickness are selected.
Considering the reduced visibility across the rear of the townhouse, there could be an opportunity to consider thermal improvements such as secondary glazing or slimlite double glazing, as part of a whole home approach to energy efficiency. However, this would be highly dependent on an appropriate assessment of potential heritage impact and harm, the public benefit of whole home carbon savings and the appropriateness of the glazing profile and finish.
