Janina, I had the same problem with our frosted glass bathroom window; my solution was to put a large plant on the windowsill - privacy restored!
My main regret is not installing a fan in our basement utility room; it gets very humid when the dryer is on.
Buying two 'stylish, trendy, contemporary basin taps' that make an awful noise when used.
Also, as other have mentioned, not checking electricians' work - we ended up with far too many awkward placed sockets in some rooms and not enough in some other. Plus, we have twelve, 12! light switches in the kitchen; only seven of them working...
