We've started work on an extensive upgrade of a listed building in Oxford’s historic city centre: 19-21 St Johns Street, three late Georgian Grade II listed buildings used for student accommodation for nearby St John’s College. The £4.6m project is set to significantly boost energy performance.
To achieve high energy performance standards, Beard is upgrading the external fabric of the building to drastically reduce heat loss. It is also installing high performance woodfibre insulation to the internal face of the building. This will greatly increase energy performance at the same time as allowing traditional stonework to breathe. The works include replacing gas boiler systems with air source heat pumps to provide heating and hot water.

To improve air tightness and soundproofing, we're also upgrading the windows with sensitively designed, secondary internal glazing. The design team has carefully pursued this approach to minimise the impact on the external appearance of the listed buildings. We're working to protect and retain the building’s special historic features, including existing floors and stonework.
