The rear windows to the garage and original dining room store have been removed in blocked up. The dining room store was outside of the thermal envelope of the house, completely uninsulated floor, roof and walls – a real cold spot. The final house will not be short of storage space, but we decided that it would be useful to have some utility storage accessed from the garage. This decision also helps with awkward thermal detailing – i.e. we don’t need to incorporate the store within our thermal envelope. That said, and having just noticed on the photo as I am posting this, I realise that we haven’t incorporated the external wall insulation between this block infil and the existing house walls. A thermal bridge to deal with – any ideas? Ruairi?
