Answer : What does your home design project include? If you only want a designer to come into your current space to assess what can be done with it, then the cost should be much lower. However, if you want a designer to redesign your entire space from scratch, then the costs will probably rise substantially. This is because the design will have to take everything into account and figure out how all of these factors can work together to facilitate a desirable flow. To give you an idea of price variations, a baseline renovation might cost about $50-80 per hour for labor for admin time alone.
