On site in Suffolk – the conversion of an existing barn in the curtilage of a Grade II Listed house, to provide annexe accommodation for the client’s parent. Progress is being made with repairs to the historic timber frame, which will be left exposed on the inside of the building. The frame is being retained as much as possible, with localised replacement timbers being installed where necessary. Once the frame is repaired, insulation will be added, using a combination of blown hemp insulation between the frame and woodfibre boards over the outside face.

Above, the existing roof will also have Pavaflex woodfibre insulation fitted between the rafters, with woodfibre boards below. These natural, sustainable insulations will provide a significant improvement in the thermal performance of the building. They are fully breathable, naturally regulating moisture levels and reducing the risk of internal condensation, damp and mould – thereby providing a healthy living environment. Pavaflex also has high levels of thermal mass, meaning the roof will be insulated against summertime overheating. Internal finishes will be in lime plaster, which is both breathable and beautiful.

Works are being carried out by John Cowling Builders. Watch this space as we follow the progress of the project on site!
