What distinguishes modern strip malls built from the 1970s to present?

The distinguishing feature of modern strip malls built from the 1970s to the present is the use of lightweight truss assemblies and common attic space. This design approach allows for efficient construction, improved flexibility within the interior layouts, and often results in lower building costs. Lightweight trusses, typically made from engineered wood products or metal, provide adequate support while reducing the overall weight of the structure. The incorporation of a common attic space helps in accommodating mechanical systems and facilitates easier access and maintenance.

In contrast, heavy timber frame structures are not a hallmark of modern strip malls, which tend to favor lighter materials for cost and efficiency reasons. While some modern strip malls may be single-story, they often include attic space for various purposes rather than being explicitly designed without it. Finally, while reinforced concrete is used in construction, it is typically not the sole material used; a combination of materials is common in modern designs, making this option less representative of the overall characteristics of these shopping centers.
