welcome to or welcome in

"Welcome to my house" or "Welcome in my house" ?
Despite the previous threads I'm still confused .

Hello Tina,

it is always "welcome to" when it is used as an exclamation, so only your first sentence is correct.

As to "welcome in/at," these previous two threads might help you:
Welcome to my house/You're welcome in my house.
welcome to - welcome in
