House Design Flaws

Having just moved into a new place, we're getting a fresh view of "how not to design a house."

1.  If you plan on renting your house, NO BUILT-INS.  Seriously, we have our own furniture.  It's nicer than your built-in.
1a.  If you do have a built-in entertainment unit, make sure that the cord pass-throughs are big enough to pass a cord through.  Just sayin'.
1b.  If you must have built-ins, make sure they are built IN, not OUT.  If it's built IN, I can at least put something better in front of it.
2.  Light switches should be the closest switch to a doorway.  Not the fan switch.
3.  There should be a fire alarm in the kitchen.  If there is not, there should at least be one closer than half the house away.  I get as annoyed as the next person when the fire alarm goes off while I'm cooking dinner, but I get much more annoyed when my house burns down.
4.  Think very hard about where you put such useful items as outlets, cable and phone hook-ups.  Hint: hiding the cable jack inside the closet is not very useful.
