"Finally an honest Solar company!! I went through several companies trying to get quotes for one of my properties, either they were ridiculously expensive or they didn't return my calls. A friend of mine referred me to Mega Sun and I have to say I am very pleased. Within a couple days from the initial phone call I already had an estimate and once i decided to go with them the installation was completed in one week. Its been a little over a month since they completed the install and everything is working smoothly.

I was amazed at just how great the customer service was. I just want to say thank you to the whole team who helped out, I really appreciate all your hard work. Now I know you guys are the ones to call for all future jobs."

Barndominium Builders FAQs, answered by experts

Whether you buy a prefabricated shed or build one depends on why you need it and where you stay. For instance, if a simple garden shed is what you’re after, it’ll be less expensive to buy one already built. But if you want a shed with windows, plumbing, and electric work, a custom-built unit might be more suited to your needs.

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. 

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.

Skid foundations, deck block foundations, and concrete block foundations are the most affordable shed foundation options. Of these, we recommend deck blocks. Deck blocks are easy to install and level, and they raise your shed up off the ground to prevent rotting from exposure to water and moisture. Keep in mind that deck blocks won’t resist soil movement or frost heave, so they’re not ideal in areas with expansive soil or a deep frost line.

The time it takes to build a shed heavily depends on the type of shed you buy. A prefab shed can be built in 4 to 8 hours, while a custom shed will be built off-site over the span of 2 to 5 days. It then takes a few hours, depending on the location, to move the finished shed to its final location.
