OK, I'm not sure that this is very successful, but I had to start playing with this concept once I thought of it. I would really love to have your feedback on my designs. Thanks so much for your consideration!
OK, here's one more idea. I'm really just trying to flesh out some lettermark ideas, though it may not be your preference. Though a lettermark is a very good way to nail down a fresh and unique logo. This one in particular makes me think of a bird's eye view of the roads in a development, with a cul de sac or roundabout included. Thanks!
I really like entry #4 but I'm wondering if you can try something out for me. Our main focus is on Commercial & Institutional buildings - instead of a house could you put an office building or some other type of commercial building in between the G and the 3? It might not turn out great but I thought it was worth a chance of trying it out.
