"Mike and the people he works with are great. Very professional work. Provided most thorough proposal with pictures and explanation of costs, got started quickly, and worked around our schedule. Didn't skimp on quality materials. A few instances of not receiving information and project stalled a bit towards end. Some was supply chain, some was probably focus on other projects. Overall, very happy with basement remodel. Transformed and looks great!"

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.
