No two remodels are alike. And there are many variables that will play into the cost of your project. There are two basic ways to budget for a project. The first is to design to a specific budget. You first determine what your budget is going to be and then base your space design and product selections on that budget. The second way is to design the project and assume "it costs what it costs". You may decide you want to do a complete remodel of your exterior all at one time. Either way works. It's all a matter of what you're most comfortable and allows you to meet your goals.
