With several years experience, we work hard to bring each customer the best possible service and quality available. We look forward to working with you on your next project. We welcome your questions and thank you for your interest.

"I can't say enough good things about Justin and Affinity Construction! Our project went from a wood frame RV carport 20x45 to an enclosed garage. Justin came out several times as we worked through the build plan. Affinity was covering all the bases from foundation to paint color. Justin is great to work with and goes the extra mile to ensure the customer gets what they want. Unfortunately, the city had easement issues on the build site and wouldn't allow a structure to be built. We had no other suitable location for the garage, so the project was scrapped. This is when I decided Affinity Construction would always have my business. Justin returned my deposit, and went further introducing me to other professionals he trusts to bid on the smaller side projects we were going to do while the garage was being built. The true measure of a quality company is how they react when things turn sideways and how they treat their customers when money is no longer changing hands. 10 stars!!"

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.
