Pre-engineered structures are perfect for office buildings. Clear span allows you to break the office layout anyway you want and allows you to offer suites. Many add masonry fronts and storefront glass for curb appeal while getting the cost savings of a pre-engineered structure.
One of the beautiful reasons to choose a pre-engineered metal building for an office/retail space is the color options. You can even get stucco embossed panels that give the building a stucco look but withstands the elements.
