Carefully detailing the floor plan will minimize any potential guess work for contractors and designers who will be working on project. Knowing the tools you have to work with to help you design the layout is important and will save you money and time. CAD software is costly with a high level of difficulty, especially if you are not computer savvy. Hiring a architectural firm might be expensive, but will ensure the most accurate design results.
