"I hired this company to lay wood flooring throughout the house, to refinish the stairs and to replace all banisters and railings. I couldn't be more please with how this project came out. The people that worked here were professional and did a phenomenal. Hands down, some of the best people I've worked with. They showed up on time, the quality of the work was fantastic and they left my house cleaner than when they started. I was so pleased with everything and everyone related to this job that I called them back to renovate my kitchen. They are the only company I will use going forward. I was lucky to find them. "

"Bob and his crew are the best. This was a major renovation and complete re-do of a split level house that we converted to a more traditional house. 95% of our house was redone. Bob is meticulous and his subcontractors are fantastic at their crafts and very loyal to Bob for good reason. He was pretty instantaneous in his communication with me even on weekends, which we rarely bothered him in. This was a mid 6 figure job that Bob said would take 4 1/2 to 6 months. They finished in 5 1/2 months which is pretty amazing during a pandemic with major supply chain issues. Bobs bid wasnâ t the lowest, but it wasnâ t the highest of the 5 bids we received. They were pretty much on budget except for material price increases, especially lumber which was not his or the lumber yards fault. If youâ re thinking of hiring MZ Development you will not go wrong if you hire them to do whatever size project you are thinking about."

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.
