Modernization of the terrace and bathroom - costs

Please upload the photos here, I don’t click on links. Do you mean a window by Glasfront? And how big was the bathroom again? Between 8 and 12 there are 4 sqm.

Yes, but what does the terrace front look like in winter? I would assume that with an older model, the cold would already penetrate all the way into the living room, right? : By glass front, it means what apokolok already said :) Sorry, I saw the function too late. My girlfriend thinks 10 m2 would already be a large bathroom.

Well, either you have the money and replace the windows right away or you just watch it for one winter. I also have a conservatory from the 80s, but made from some kind of tropical wood, quite high quality, and sure, it’s a bit cooler in winter, but you can still have breakfast in it at -5°C outside temperature. The carpenter I trust said definitely don’t replace them, they would be priceless today, maybe just replace some seals here and there.
