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"

Five Star Bath Solutions of Minnesota is a full service bathroom remodeler specializing in bath and shower remodeling and installations. We offer leading solutions for bath and shower remodeling, including custom bath-wall systems, new bathtubs or tub to shower conversion, walk-in bathtubs, vanities, flooring and much more. We provide quality bath and shower remodeling at an affordable price.

"Bathroom wet space (tub) remodel with Five Star Baths went smoothly for the most part! The transformation is stunning! The quality of the work is exceptional—everything looks polished and feels durable. Communication was somewhat challenging. It was difficult to find a suitable time to connect and discuss the project in detail within my work hours and the hours they have available. Additionally, the final inspection took longer than expected to schedule. I had to personally reach out to coordinate a time that would work and had the expectation that someone would reach out within the next few weeks after the renovations. While this added some extra steps to the process, once the inspection was arranged, the team was efficient in completing it. Overall, I’m thrilled with the end result and would still recommend their services!"

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.
