Officer report

Heritage impact

The heat pumps would cause a low level of less than substantial harm to the listed building, but the scheme would improve sustainability.

“The ASHPs previously approved as part of application ref 22/00388/FUL were more industrial in scale and form. The current scheme proposes four smaller ASHPs which are of a more domestic scale and as such there will be no requirement for acoustic enclosures. The units would cause some harm to the setting of the listed building and its bow window which overlooks this space.”

“The identified minor level of less than substantial harm to the listed building arising from the ASHPs and associated works is outweighed by the public benefits in the form the removing reliance upon non-renewable gas supplies and the decarbonisation and improved efficiency and sustainability of building stock.”

Officer report

Specialist advice

The Conservation Officer was satisfied that the internal plant, pipework, electrical supplies and additional radiators would not cause adverse heritage impacts.

“The scheme will involve the installation of associated plant equipment within the basement which is accessed via the courtyard. The necessary associated pipework will require two new 100mm diameter penetrations through the fabric of the building to allow for flow and return pipework to reach the plantroom and the electrical supplies for the ASHPs. This will be supplied from the new Molded Case Circuit Breaker (MCCB) panel board in the basement switch room.”
