Arcanna Homes, Inc., is a family run home construction company that's been in business since 1989. From stick built to panelized structures, we use the fastest, highest quality home construction method available and can supply all necessary design, accounting, project management and professional labor. A new home or home addition built with Panelized Construction Technology can easily be customized, weather tight and secure in days and exceeds today's rigid construction financing terms! Panelized structures use cutting-edge automation and are built in factory-perfect conditions. Complete exterior and interior wall panels are pre-engineered and shipped to the building site for final assembly, offering substantial time and cost savings. WATCH THE VIDEO: https://youtu.be/7k81cF7p2rM

"I would recommend Arcanna Homes in a heartbeat. I had a kitchen renovation done (and I have a very small house) and we were treated like we were building a brand new home. Ralph answered all my calls (even when he was away) and even met with us over the weekend to help us pick out cabinets. His workers were all efficient and great (even through the hot July weather)."

We carefully select quality products, and use proper installation procedures to ensure timeless results. Specializing in kitchen and bathroom remodeling, our company also offers a wide range of interior and exterior improvements: drywall, painting, replacement windows, doors, carpentry, flooring, and more.

"We have a smaller upstairs bathroom that had not been touched since 1975. The shower had been unusable for over a decade due to leakage. The space had to be completely gutted down to the studs and completely redone. The contractor we had used several times over the years retired, so we needed someone new who we could trust. Radical Renovations (Angelo) was recommended to us by N & S Supply in Kingston and I'm SO happy we hired him! He's professional, responsive, patient and finds solutions to all issues that invariably come up when you're dealing with old homes. Plus, the crew who he brought in to work with him was also pleasant and professional. I would absolutely hire Angelo again...in fact I already am!"

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.
