There was nothing wrong with the window in the 'new' house which we made into our office. It didn't really need to be replaced. But: 1) It was made from aluminium = it was pretty ugly in an old house. 2) it was a sliding window = you could only open it halfway. And 3) It was frosted, so you couldn't see out of it. At the end it had to go. But it didn't go to waste, because once it was out and put in the back it varnished - so no need to feel bad. Right?
Besides, I've seen an old photo of our facade at Rafae'ls house. And it showed a wooden window frame. Much smaller though, but they all were in the old days. They hade no glass in them. I'll ask him to borrow the photo again so I can scan in and put it up here-
