"As a first time home buyer, I was already facing a new and stressful situation all by myself. I was aware when I purchased the home it would require work prior to moving in. I sent request to multiple handyman and larger companies to obtain a quote and estimation of time for being able to complete what I need to be able to move in, and then the remaining work. I received quote and estimate on time from this company faster and prompter than any of the other companies I submitted too. After receiving a quote, they came out to my home after scheduling a time frame. They arrived and followed me through the house, paying attention to the details I requested, took notes on everything I was wanting and requesting, and Kareem was able to understand exactly what I needed done. I asked Kareem and his company to run and replace the wiring in the kitchen, the wiring was so old it was at danger of arching and catching fire, and I needed the basement to be waterproofed by installing a sub pump and the entire drainage and pipe system. I informed Kareem I had to have all of this completed within three days, I had to be moving in on the Fourth day, not only did he complete it within the time frame, he completed on the second day by noon, giving me extra time to move in. I was more than happy with this of course, however, as to rewiring of my kitchen he was able to place plugs above the counter tops in very convenient places for me, making life easier. As to waterproofing my basement, the completed work looks amazing, and I am unable to tell that the concrete floors had been ripped open, and was done perfectly. I would highly recommend Kareem and his Company any day and to any of my friends and or family."

Barndominium Builders FAQs, answered by experts

Concrete blocks are the cheapest way to base a shed. However, the space in between allows critters to go under, burrow, and even damage your shed’s frame. For a more pest-proof option, consider building a shed base with gravel or paver stones. Both options are fairly affordable and easy enough for a DIY project. For gravel, you can build a wooden frame to contain the loose material.

This answer varies based on where you are, but most states require that all homes are greater than 320 square feet. Remember that four walls are not the only requirements—windows, closet space, minimal ceiling heights, and indoor air quality are also factors. Each state and municipality differs, though, and as some don’t consider tiny homes permanent shelters, you’ll need to check to ensure you aren’t violating any local or state laws with your build.

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. 

It’s much less expensive to build a house with wood. This is because wood is relatively inexpensive, strong enough to endure decades or even centuries of weathering and pressure, and is easier to replace if there are issues. The cost of stone houses are incredibly expensive, heavy, time-consuming to build, and difficult to repair. 

While a romantic getaway in a vacation treehouse may sound appealing, building one to live in year-round comes with more challenges. However, a growing number of people are adopting this small-scale living approach to appreciate an off-the-grid, private lifestyle. It allows you to feel closer to nature in a sustainable, customizable, minimalist, and eco-friendly way.
