make sure the kitchen maker has the dimensions of your appliances. make sure the kitchen maker knows where your water and gas are and need to be. moved or not moved. window finishings.make sure you can open fridge, oven, dishwasher and cabinet doors with enough room to walk through.
i ahve a galley kitchen and it is narrow. every inch counted. my cabinets for food are floor to ceiling and i love them. abover the counters i went up to the ceilings as well. make sure to request the molding be included too. i did not want 8-10 inches of space from the ceiling to the top of the cabinet for dust collection. thats all i can think of right now. good luck!
