We had an extension built last year. But the utility room is freezing in winter (gets down to 10 degrees some days), despite having an adequate size radiator (room is 2 x 2.5m). This part of the extension is flat roof and adjoins the main living area and has a door onto the garage. There is a brand new glazed door to the garden but no separate window. As part of the building regs we had to have an extractor fan installed (diameter approx 15cm). I can feel cold air coming through what is effectively a hole in the wall. The garage door is a fire door.
When we mentioned to the builder he said there was nothing to do. I can't understand how a new building that had to meet building regs is so cold? What if we were going to use it as a playroom or similar - it would be uninhabitable.
Can anyone give me any advice?
Thanks
