Ok here I am posting some thoughts on what you said earlier:
In entry
#81 I did the "underline" just a little bit so that you would see not only the roof, but the floor for the house. In entry
#80 I extended the line all the way to the beginning of the word just to make the whole thing look more "closed".
In
#84 and
#85 I added a hammer in negative space to the H in "chig"
I must say though that to me these elements crowd the design a little bit; if you would ask me, I would still go with my entry
#45 because it looks cleaner and more simple. It still has the house element to it, but it highlights more the "communication" part, which is at the end what I think the user will be looking for. "Successful communication between me and the home builder".
