"Remodel went extremely well even with material delays (not ordered through Rowe construction.) They were able to pivot and work on different areas of this extensive remodel. This crew showed up every day and notified us if they were not going to come or if they were delayed.They also pointed out and/or were able to troubleshoot areas of design that wouldn’t look aesthetically pleasing. In addition, they cleaned up the interior each day and regularly picked up construction waste placed in the garage during this process."

Addition to existing structure building services FAQs

How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.

Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
