Floor plans help potential buyers envision how they would use the space and assess its suitability for their needs, such as determining if the rooms are the right size or if the layout aligns with their lifestyle. Floor plans also make it easier to identify the flow of the space, the relationship between different areas, and how functional the design is. Additionally, they help with the decision-making process, as some buyers may prioritize open-concept living, a home office, or ample storage.
