So far I used SweetHome3D, Onshape and Qelectrotech (for electrical) for the renovation of my house.
However if you are planning to do some heavy renovations in your house I would advise you to get an architect to do a proper blueprint of your house and a blueprint of what your house would look like after renovation.
It’s not necessary, it might feel like it’s extra money up front that you don’t use directly for renovation but in a big project you save so much in the long term. This is what we did and there is so many (expensive) mistakes that we avoided because we had an expert eye at the beginning of the project.
Not pirated but my local cooperative ISP is offering to split the fiber connection with neighbors and give advice on how to do so.
We can even have two bills, two completely separated intense accesses on one fiber connection and they will split the bill in two, or three, or four (plus add a few euros for administrative fees)
