Architecture focuses on the structure and exterior of buildings. Interior design deals with space planning, finishes, and interiors. Architects design the building; designers enhance the inside experience.

Hire them early during planning or renovation stages. Early involvement ensures efficient space use and cohesive design. It also prevents costly changes later.

Costs vary based on project size, materials, and design complexity. Designers may charge hourly, per room, or a percentage of project value. Basic consultations are more affordable.
