"Platinum General Construction LLC was contacted after two initially hired contractors were incompetent in providing the remodeling services needed for our bathroom remodel in Dec/Jan 2025. Platinum stepped in and completed the work on time and as quoted. David was our primary contact. He was great as respects communication, working through issues, and coordinating with subcontractors. The remodel included heated tile floors, a curbless shower, toilet install, and beautiful tile work. We were pleased that Platinum got our project back on track and finished after dealing with the mis-steps of our original contractors."

"New Home Solutions is a Design+build firm and since we were unsure of the choices we needed to make for our kitchen remodel, we engaged New Home Solutions' design services. Marybeth was handling the design aspects and she did an excellent job with her recommendations. She helped us pick out our counter-tops, our back-splash tile, figure out our cabinet layout. She also worked with multiple vendors to give us an detailed breakdown of the estimates. She was responsive on email and made multiple store/home visits to ensure she understood and translated our needs to the estimate. Unfortunately due to vacation timing, we couldn't proceed with New Home Solutions' Build eventhough we were happy with the designs and the final estimate. Would totally recommend Marybeth's 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.
