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.

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. 

Cathedral ceilings make a statement in your home, but at the cost of your attic space. Normal attics are wide open, which allows warm air to move around and exit your home. Because of this, cathedral ceilings make your home less energy efficient and put your ceiling at risk of venting issues if you’re not careful. They also reduce your attic storage space, potentially cause an echo, and even make it harder to change a light bulb.

The architect you choose to work with should have experience with the type of design you’re interested in, a portfolio of similar projects they’ve completed, and a process and work style that aligns with your expectations. A seasoned architect will be able to provide you with all that information so you can ensure they’re a good fit.
