Since i think the wyvern doesn't count as a worm mob (correct me if I am wrong) you could try a house with lave surrounding it, then the wyvern will fly through (if I remember correctly then it can go through walls) the lava and kill itself, or at least do a bit of damage to it.

If you don't want to bother with that then just go ahead and make a house that isn't high enough to spawn wyverns/harpies but still high enough that it is easier to get to space from there (about halfway, before you start hearing the space music theme)
