Subcontractors FAQs, answered by experts

Yes, custom designs match existing structural and aesthetic themes.

The country's most famous Neoclassical architecture appears in major government buildings and college campuses. The White House is unmistakably the most famous example, though the Capitol Building and Thomas Jefferson's Monticello are also iconic uses of the design.

Make sure you’re getting the right size to meet your space needs, including enough space both side to side and vertically to accommodate your RV’s features and allow you to safely move it in and out of the garage. 

If you’re building an attached and enclosed garage for your RV, you’ll also want to give some thought to whether you’d like to add workspace, water or electricity, or additional storage. If so, you’ll need a garage with larger dimensions.

While it’s never too early to start planning for a major home improvement project like a home addition, give yourself at least a month or two to plan and design your addition, find a contractor, and get the permits in order. For larger projects like a second-story addition that require designing with an architect, plan on three to four months of preparation.

Yes, professionals can offer design advice and material selections that complement existing architecture.
