Edinburgh New Town law firm — listed building 95 kWp install
Edinburgh New Town law firm — listed building 95 kWp install
A long-established Edinburgh law firm occupying a Grade II* listed Georgian townhouse in the New Town World Heritage Site needed to address looming MEES regulations and growing client Scope 2 disclosure demands. The building footprint was small (1,800 sqm net internal area) and obviously heritage-sensitive. We designed a 95 kWp install split across concealed rear-roof areas and a single-storey rear extension, with full Heritage Impact Assessment and pre-application consultation with Edinburgh City Council heritage officers.

What the customer said
“We feared planning would be impossible on a Grade II* listed building. The concealed rear-roof design got Listed Building Consent in 11 weeks. The system has been completely invisible from any public viewpoint.”
