An architect is usually hired to plan, design and manage a remodeling project from start to finish. You probably will not need an architect if you are doing a simple remodel and you are not enlarging the area or adding a large amount of weight. If you are enlarging the area, moving the kitchen to another part of the house (the garage, for example), moving or removing load-bearing walls or creating a professional kitchen, you need an architect. If the structure of the house can or will be affected by weight, by changes in the way the weight of the house will be carried to the foundation, or if you are making major structural changes, you are well advised to engage an architect.
