I saw this property in another thread and was really surprised by the roof trusses in the loft/bedroom. My first thought is that this roof is an illegal conversion to living space though that may not be the case. I'm wondering what the cut-outs are in the trusses? Maybe it was wood recycled from some other place & it already had the cut-outs? I'd be interested if anyone has any knowledge.
