I founded American Pioneer Construction in July 1993 to give my customers top quality design and installation in a timely manner and at a fair and competitive price. Our goal is to help you create your dreams.We are fully licensed in Westchester and Putnam counties in New York. We have a multi million dollar insurance policy which has never been used in 30 years. The reason is that cleanliness and safety are our top priorities. We are on site every day until the job is completed. We have massive experience in indoor and outdoor renovations for your home. Indoors includes kitchens, bathrooms, basements, doors, windows, moldings, additions, and custom cabinet and shelving units of any size. Also, outdoors we build decks, covered porches, walkways, patios, and fire pits. We have built over 300 Koi ponds that have been featured in international magazines and huge pond tours. We also frame/build garages,sheds, and outdoor bars. Give us a call so you can find out how we can help you.

"American Pioneer has renovated 90% of my home over the past 10 years and has always done a great job. The price for the work has always been reasonable and the price quote at the start of the job is the price paid at completion. They show up when they say they will be there and stay until the job is finished. The work product is always top quality which is why we’ve used them to renovate almost every aspect of our home. I would highly recommend their services."

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)."

FAQs for addition to existing structure building service projects in Cornwall, NY

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
