Low-carbon listed-building works at Council Offices, London Road, Saffron Walden

“PROPOSAL: Replacement of existing gas boiler with air source heat pump system and modifications to the existing distribution system. Insulation of solar PV system. Installation of loft insulation and secondary glazing…”

“The site comprises the Council Offices on London Road, Saffron Walden – a large Grade II listed building dating from the 19th century, constructed in brick with slate roofing, and set within landscaped grounds. The site lies within the development limits of Saffron Walden and within the Saffron Walden Conservation Area. The surrounding area is largely residential.”

“The works include an air source heat pump system, solar PV panels, secondary glazing, and loft insulation. These interventions have been carefully designed to respect the building’s fabric and appearance, with all works fully reversible where feasible.”

“The proposals would preserve the special architectural and historic interest of the listed building and deliver meaningful sustainability benefits.”

“The external works, including the installation of the ASHP units and PV panels, would be positioned on discreet roof slopes and within service areas at the rear of the building, minimising their visual impact. The internal works, including secondary glazing and insulation, would be reversible and would not involve the loss or concealment of any historic fabric or features of interest.”

“The Councils Conservation Officer concluded that the internal works within the historic part of the building are expected to result in a very low level of harm to its significance, due to minor interventions to the historic fabric. However, the proposed alterations will not affect the building’s character and are considered proportionate and necessary to support the decarbonisation objectives.”

“The overall proposals are considered acceptable. The application provides evidence of a rationalised scheme that considers the historic fabric, and the impact of external elements on the character and appearance of the conservation area.”

However, the proposed alterations will not affect the building’s character and are considered proportionate and necessary to support the decarbonisation objectives.”

“A site notice was displayed on site; the application was advertised in the local press and notifications letters were sent to nearby properties. One objection has been received raising concerns in regard to noise. This is dealt with within the associated full application.”

“Councillor Emanuel proposed approval of the application. This was seconded by Councillor Church.”

“RESOLVED that the Strategic Director of Planning be authorised to grant permission for the development subject to the conditions set out in section 17 of the report.”
