"Wonderful communication from day 1. Very pleasant to work with and Very professional. My wood deck was in bad shape and needed to be repaired, power washed, stained and sealed. The job was done with care and knowledge and done very well. The deck looks great! I highly recommend Star Dynasty and will use them again when I need work done on my home."

"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."

"I am incredibly thankful to Ray LaManna and Tri Build Construction for my new roof. I had major structural damage to my roof due to improperly installed solar panels. Not only did Tri Build diagnose the leaks before the repair, they fixed it in record time. It was extremely reassuring to know what the cause was and how it would be resolved so that I would not have to worry about my home, my greatest investment. If you have roof damage due to improperly installed solar panels, or if you’re looking for a new roof and need a competent and honest contractor, you need Tri Build Construction, a U.S. Veteran owned company."

Barndominium Builders FAQs, answered by experts

Your foundation contractor will first need to remove the topsoil and any vegetation within 4 feet of the area around the barn. They’ll need to ensure they have clear access to the site to begin excavation, after which they can begin construction.

It may be tempting to DIY the construction of a swing set to save money, but we don’t recommend it. Since children will use the swing set, the entire system must be solid and safe, meaning the cost savings aren’t worth potentially endangering them. Plus, most DIYers will have to build their swing sets out of wood, which won’t last as long as metal or vinyl and introduces the risk of splinters. Instead, hire a local playground equipment installer to ensure the swing set is built safely and efficiently, setting up your kids for fun for years to come.

It is recommended that you check with your local building official on barn building requirements and rules, since size restrictions vary greatly from region to region based on what your property is zoned for. Some cities limit barn construction depending on if your property is residential or commercial. The three main factors your building commission will evaluate are:

  • Height and lot coverage: How tall your barn is and how much of your total property it occupies

  • Setback: Distance between barn and property line

  • Easement: Legal right for another owner to access another’s property

The steep slope of an A-frame roof withstands high winds, heavy rain, and heavy snowfall, making them popular all over the world. A-frames also offer simple, quick construction. Finally, an A-frame typically has large windows on the non-roof sides to let in a maximum amount of natural light. Consequently, they are often an affordable building solution for the right homeowner and location.

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.
