The home our architect drew up for us was literally an intricate puzzle to frame...multileveled roofing, angles, jut-outs, a walkway ceiling that appears to be floating, etc....gratefully, the O'Conner Construction crew was up to the task! Their careful work resulted in a structure that we feel confident and comfortable to live in. The crew was friendly and they were all very skilled workers. A bonus was that the job site was kept neat and clean. We definitely recommend this company!
