New single-family house in southern Germany

People with basements and corresponding storage and shelter potential (see among others "War of the Worlds" and "10 Cloverfield Lane") will triumph!

I once had a craftsman in the basement. He just said: "You will definitely survive the 3rd World War." You don't joke about something like that, but basically my basement is a small supermarket, and the neighborhood appreciates that too.

Future party room in the new house. A foosball table and a pool table will go in there, along with the foldable ping pong table.

Above ground, with real windows certainly great. . . . . I would also paint the bay window :p

Don't forget the bar and the appropriately large screen - possibly for football etc. - :D

... I would also remove the bay window :p

Remove (take away) or paint (color)?

Won't be removed, will be wallpapered :p.

Cancel (remove) or cancel ("paint over")?

Remove. It's too old-fashioned for me. Maybe turn it into a wall cabinet and disguise it ;)
