Don't get me wrong: If I were swimming in money, I would be the first to build a basement. But our budget is limited at some point.
We are building such a large cabin because we regularly get visits from 3 part-time children (from my husband's first marriage). So two more children's rooms. But since the older ones are already 16, 14, and 12 years old, it is foreseeable that the two children's rooms will eventually be converted into an office and/or "storage rooms."
We now have 120 sqm with an additional basement room. With another 85 sqm of basement space, we would have so much space that we don't even need. And it also has to be kept clean (sorry, housewife thinking...).
But OK, I will now wait for the offer and if necessary talk to my husband again.
@ Der Da Yes, we need to talk and honestly, I am not willing to put more money into the house construction and have to restrict myself for life.
