Stairs help anyone?

I'm revamping the European Townhouse and I deleted the stairs that you can see on the first floor. The stairs only seem to be 3 squares long, and now when i try to change the stairs it says cant reserve space above stairs since it requires 4 open spots. When I look at the connecting stairs pop up it says click and drag for finer control but it doesn't work; possibly these stairs are only meant for outside? But if they were then how did they put them in the house in the first place, tricky tricky people they are. Does anyone have any idea on how to make a three square long staircase using the normal connecting stairs? [ sorry for the long description]

Whenever the tooltip for the modular stairs say "can't reserve the space above stairs" just delete the wall in front of the third space, place stairs, then replace the wall. That works for me.
