Roomsmith™ opens the possibilities of your house - we are the market leader in room additions and basement conversions, providing fast, high-quality installations with a seamless process.

"Roomsmith displayed a complete lack of professionalism throughout the entire project, from poor communication and constant delays to shoddy workmanship and a blatant disregard for trash left on our property. They failed to return calls/texts promptly and sometimes we didn’t hear back from them for weeks. We experienced frequent delays, ignored concerns, and not taking responsibility for issues like ordering the wrong window (and their professed ability to obtain this exact window is one of the reasons we chose them). They also completely overlooked part of our project (a small closet turned into a pantry) by not ordering any shelves even after the cabinet company told them multiple times that they never measured for them. They overlooked details like the floor transition not being flush and part of our old door frame wall is still there and shouldn’t be. Our project didn’t seem like a priority, more like an afterthought that they didn’t care about. They did not adhere to project timel"

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.
