In most cases, you do not need an architect to design a kitchen. An interior designer or a kitchen designer may be better suited for this task, as they specialize in creating functional and aesthetically pleasing living spaces, including kitchens. However, if your kitchen renovation involves significant structural changes, such as removing walls or installing new windows, an architect may be required to ensure that the changes are made safely and in compliance with building codes. It's always a good idea to consult with a professional to determine the best approach for your specific situation.
