Which company built this house - is there any more information?

Oh dear, thanks for the hint, we feared that. With electric blinds over all surfaces, right? That will surely be expensive.

Only the year of construction 1996 and the floor plan are available as information, and that it is a timber frame construction (if I am reporting that correctly).

Then show what plans you have. Several people can read such things here.

The location is in Baden-Württemberg, the specific house is the second from the left in a row of five houses. And we are aware that not-so-new houses in this type of construction can have their pitfalls - hence the question. [...] But besides a "finite" life expectancy of the house, we also fear hot summers because of the glass facade.

In a row of five there are four neighbors in the same situation, you can ask them. The houses will be individually designed. A timber house builder is usually only selected (or even active himself) in developer projects if he is based in the area. Even after 1996 there were still bankruptcies and mergers, so the manufacturer may no longer exist as such. I know the industry but don’t recognize the style of any of these here. If your actual "question" is rather the concern that these houses would prove to be cheap rubbish after twenty years, you can be sure: this is unfounded. Nothing more can be said on the narrow basis of your current information.

Which directions are we talking about? I mean… and this very explicitly: this is about a mid-terrace house!!! where you’re usually just glad to get any sun into the house at all! I think starting with that is the wrong approach here. I wouldn’t know either why someone would be so overly cautious with a building year 1996. Expertise is clear… but you don’t have to exaggerate with the anxiety now.

Thank you, I see more clearly now. And I gladly accept the offer with the plans.

The upper floor is missing... For a "retirement home," there would probably be too many stairs for me. There isn't particularly much on one floor...

Yes, one must not become frail there. And somehow I can't find a north arrow on the plans. Which cardinal direction are the glass fronts facing? Are there large trees or neighboring buildings that shade them? Terraced house and overheating unfortunately do not necessarily exclude each other. You can also easily simulate the sun's position, just enter it in the search engine of your choice.
