I made the hugest mistake of buying an Allen Edwin home. When it was being built, I requested 16 on center for the floor joists. When the home was built, they did their usual contruction of 24 on center. I was mad. They didnt listen to a thing I said. When I called them, Allen Edwin acted as if it wasnt their fault. I got a stream of lame excuses and half hearted apologies and even got accused of it being my fault for not clearly explaining what I wanted. How much clearer did I have to be with them? It was in the blue prints. They do a standard 24 on center floor joists to cut corners and save money for themselves. I wonder what other shoddy construction they do to save money??? I have this terrible feeling I am going to have many problems with this house. Allen Edwin stinks, do not ever use them!
