From my stud - 50 studs. That's what he bought me. I'd told him all I wanted for Valentine's was for him to start tearing something out.
So he did.
#1 most of the grandkids fit between the rails that were there, and it's 15 feet DOWN to ceramic tile.
#2 the previous owners used the room to play pool. We wanted to really, really use it, but it was virtually impossible - the open walls showed backs of tables, electrical cords, etc. fully viewable from the first floor. Not the look I was really going for.
#3 the home office was crammed in there too, sitting a whole foot from the TV.
#4 if, say, someone wanted to read in bed and someone else wanted to listen to late night TV it was impossible to shield the noise from the open room.
Enclosing it into a separate 'bonus' room as they call them here in the south will give us a true, separate room that won't let any grandkids fall through; will hide the backs of furniture etc. He's putting in a separate office nook for us, with the computer viewable from the hall, rather than in a closed room. Much better as grandkids start growing up. And I can break up with Jay Leno for good. Eventually it'll have four walls and a door that closes so it'll be a great place for grandkids to flop on sleeping bags or the sofa as they get older.
Sexiest valentine's gift E.V.E.R. Thanks stud-muffin. You sure know the way to a girl's heart.
