Large occupiers are more efficiently using warehouse and distribution space, resulting in increased building clearance heights. This has made measurement of cubic feet, or the "third dimension," more important.
Taller warehouses exponentially increase the total volume of inventory available to occupiers. Since 2010, there was 10 billion cubic feet added to the warehouse inventory of the top 10 markets. Taller warehouses can also provide better value by offering more space to store goods for each square foot of rent paid.
