"Artie & Mike are simply the best. I used them to: 1) Build a LARGE extension to my house and redo my entire kitchen and dining room. The job was completed on time and on budget. Throughout the process Artie was transparent & professional. EVERY person who has stepped into my house has complimented at the detailed perfection. 3) Artie built us a custom walk in pantry 2) Built 2 large decks in the backyard as well as an outdoor shower. This project was completed on time, on budget while exceeding all expectations. If you are looking for a contractor and crew that is responsible, responsive, polite, creative and delivers the HIGHEST LEVEL of quality - Artie is the one."

Barndominium Builders FAQs, answered by experts

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

Complex plumbing is tricky and expensive in an off-the-ground dwelling like this. By considering options like composting toilets, rainwater collection, and gray-water sinks, you save money and help the environment. 

Prefab sheds can be worth it, depending on your needs and goals. If you want to build the shed yourself or have a quick project turnaround, then a prefab shed will likely be worth it. If you want something more customized, then starting from scratch may help you achieve your goals better than a prefab could.

Yes, barn doors can be too heavy, although the limitation is usually imposed by the mounting hardware you buy and not your home’s framing, unless you’re building an unusually wide door. To keep the weight down, you can opt for 1-by material rather than 2-by material, and choose a softwood like pine rather than a hardwood like maple or oak. Check the weight limits on your mounting hardware, and always attach your door track to studs rather than to drywall anchors.

Building a barndominium means converting a barn into a house. Barndominiums are becoming popular as spacious and stylish alternatives to typical housing structures. Old barns that become houses traditionally consist of wooden construction. However, newer structures, such as pole barns, often contain metal exteriors and roofs. Converting a metal outbuilding into a house presents an excellent opportunity to create a barndominium from metal.
