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. New conservation style rooflights have been installed for natural light, and new triple glazed Velfac windows have now been supplied and fitted by okoHaus. These sit outside the historic timber frame and have been carefully positioned to work around the key timbers, sitting in new timber lined openings formed on site.

New natural insulations have been added to the previously uninsulated barn, with wood wool board fitted to the outside of the timber frame walls, and blown hemp installed between the frame, filling in all the gaps between the wonky historic timbers. Above, the refurbished roof has had 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.

Supporting structure has been installed for the new cantilever staircase up to the mezzanine floor, which will be finished in bespoke oak treads. The floor is now ready for new screed to be poured, after which we can look forward to seeing the floor finishes, kitchen, and bathroom installations.

Lime plaster, which is both breathable and beautiful, has been applied over the internal insulation and will be decorated with a breathable clay paint. The internal spaces have a fantastic warm, soft feel to them and the barn is really beginning to feel like a home despite being unfinished.

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