"We now have a beautiful kitchen. This price tag was on the high end, but that may have been due to either the high price of lumber at the time (Canadian wildfires) or the customer cabinetry that we needed or both. There were a few instances where I was glad we were on sight as I don’t know if the errors we saw would have been caught prior to them being installed. The upfront design and visualization is top notch, as is the quality of the material. The labor used to install was three star at best."

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.
