Tarka is in the garage with the hood up and the side screen panels open. I'm fortunate that condensation isn't a problem as the garage was built so that an owner could convert it to rooms, if wished, so the walls are either shared with the house or insulated cavity walls, The window is double glazed and the roller shutter is also insulated. It has never dropped below 5c and is normally at 10 to 12c in winter.
