Hello

I currently live in a Hultsfred house built in 1969, single story + basement.
We plan to build a new house in 3-4 years and will then sell the one we live in today.
Currently, there are no moisture problems (we have a dehumidifier and thus a relative humidity of about 50%).
The floors and walls in the two large rooms are of so-called risk construction (according to the inspection report when I bought the house in 1996), meaning walls and floors with wooden frames and Masonite/chipboard, as well as insulation directly against the concrete wall. I don't know exactly how the constructions look, but I don't think there is any built-in ventilation.
Now, to the question…what should I do with the basement??
When the neighbor was going to sell their house, they had big problems (nobody dared to buy) because the inspection report stated ”risk construction”.
The floor is relatively easy to address; I can just tear up the existing floor and lay tiles instead (I live close to the ferry to Poland, so one trip with a big trailer…). The same goes for the toilet and laundry room, where I can put up tiles.
I plan to tear down all the wood on the exterior walls (which are concrete) as well as on the interior walls (which are lightweight concrete and concrete).
After that, the interior walls will be covered with plasterboard on thin wooden frames and wallpapered with fiberglass weave that will be painted.
The big question is, however, what to do with the exterior walls…is there anyone who has good suggestions for a wall construction that is not a so-called ”risk construction”?

If you must have separated walls at all costs, build with steel studs, not wood. Otherwise, I think the best way to handle old basements is to remove the separated walls including the insulation, plaster the walls and insulate on the outside instead (isodrän or similar).

But if you spend money on this, will you really get it back when selling? And is it really that hard to sell otherwise? How many houses older than twenty years don't have the word "risk construction" somewhere in the inspection report?
 
It is precisely this balance that is difficult... how much does it pay off to do (= will you get back at sale - tax) in relation to cost... my assessment is that I at least need to remove what can be seen as a risk, as it is more negative than positive. How much is then worthwhile to restore... hmmm maybe tiles on the floor and plastered+painted walls??

Now you have the answer, :)

The only thing that unfortunately happens is that energy consumption goes up a bit, but that's the next person's problem, one might cynically say. Otherwise, it is right with plaster and insulation on the outside.
 
Don't really know, but which feels worse, "riskkonstruktion" vs "unfinished basement"?

I thought that an alternative might be to just tear it out, clean up, but not build anything. Give prospective buyers the opportunity to see the potential in the room and build it up the way they want. Maybe requires the "right" buyer to a greater extent (=young couple where the guy dreams of a home theater room)?
 
How is the drainage? If it must be done anyway?... Newly drained is something that increases the price... as previously mentioned! all insulation and protection on the outside... nice plastered walls inside... increases ;)

Best regards
