I signed a contract for a zero step patio home. Here are change orders: Added a 1/2 bathroom in place of a closet. Added 3 small transoms in 2 bedrooms Added shower instead of tub in hallway bathroom Here are some issues: There’s a step leading out to backyard from back door of garage. Plan called for all drawer stacks in kitchen lower cabinets—builder unable to do since cabinets he ordered and installed came in 39 inches and drawers only come in 36 inches which leaves 1 ½ inch spacers on both sides…not cosmetically appealing. Plan called for 8ft arched garage doors. He installed 7ft straight doors. After some haggling he changed doors to 8 ft but still no arch. Plan called for 15 ft vaulted ceiling in entry way. He installed 10 ft ceiling. After blaming sub-contractor and more haggling he changed it. Plan called for upgraded granite counter tops. He installed builder grade. Plan called for stone over garage. He said plan is generic and just a guide.
