Length of a wall in the middle of a wall?

Hello,

probably this is a noob question but I can't figure it out.

In my case I try to create a room and then add the walls.

The room has the length 276cm x 307,5 cm.

But when I try to extend the walls the room shrinks. [:(]


I see that the walls extends in both directions but I don't see an option to change this.

Thanks in advance.

Thomas
