Gross Square Foot
Definition
The Gross Square Foot (GSF) is a unit of measurement for the total area of a building. It includes the entire footprint of the building, calculated from the exterior walls. This measurement encompasses all enclosed spaces such as interior and exterior walls, hallways, closets, and structural elements like columns.
Examples
-
Example 1: An office building that measures 100 feet by 100 feet from the outside walls would have a Gross Square Footage of 10,000 square feet.
-
Example 2: A commercial retail space with dimensions of 50 feet by 80 feet would have a Gross Square Footage of 4,000 square feet, covering all interior and exterior walls, common areas, and structural components.
Frequently Asked Questions (FAQs)
What is the difference between Gross Square Foot and Usable Square Foot?
Gross Square Foot includes all spaces within a building, measured from the outside walls, while Usable Square Foot refers only to areas that can be used by tenants, excluding structural and common areas.
Why is Gross Square Foot important?
GSF is vital for evaluating the overall size of a building and comparing it with other properties. It helps in determining the total space available, construction costs, and potential rental income calculations.
How is Gross Square Foot used in real estate?
In real estate transactions, GSF helps in the assessment of property value and potential leasing rates. It’s often used in the planning and design phases, regulatory compliance, and for achieving specific architectural goals.
What is the Efficiency Ratio?
The Efficiency Ratio is the ratio of Usable Square Footage to Gross Square Footage. This ratio helps to determine the effectiveness of the space utilization in a building.
Related Terms
