Architects FAQs, answered by experts

The primary reason homes have crawl spaces is so the foundation can reach down below the frost line to avoid dangerous soil movement and structural damage when the ground freezes. They’re more popular in colder climates where the ground freezes down to a few feet, and slabs are most popular in warmer areas where there is no frost line. Crawl spaces also provide a space for utility lines to run where they’re at less of a risk of freezing.

Blueprints are generally available for houses built after the early 1900s. Before then, detailed building schematics like blueprints were rarely used and even more rarely saved. If you have an older house and need blueprints, you can have a new set drawn up by an architect or draftsperson.

An architect is usually involved in the process of determining the layout and structural features and requirements of the home itself, taking into account the local codes, climate, and materials needed to make the home structurally sound. Architects may communicate more with contractors and subcontractors throughout the building process. In comparison to architects, interior designers typically focus on the aesthetics of a home interior and possibly exterior, helping the homeowner decide on color schemes, textures, and materials to incorporate into the design. 

Building designers charge between $2,000 and $50,000, depending on project scope, complexity, and customization.

Greek Revival architecture was popularized in America in the early- to mid-1800s, around the time when archaeologists were discovering buried ancient Greek buildings. As a means of celebrating the democratic government in ancient Greece, American architects borrowed from those newly discovered buildings as a way to emphasize that America would remain a democratic country in the wake of the American Revolution.
