"We had a pretty big project, removing an old camp roof and building a new roof rotated 90 degrees, and adding a loft area. We were very happy with Andrew and his crew. They really go the extra mile to make sure everything is done right - they don't cut corners and take pride in their work. They installed new windows in the front and even used Windex to wipe off their finger smudges! Price was very good, and they're good, honest guys to work with. Very pleased!"

"Dean has been an amazing help to me and my husband. We have used him twice now for two pretty big issues. One was a tree through our roof into our bedroom. He did an amazing job repairing the roof and redoing the bedroom. It was a super stressful time that he made easier and the work was amazing. We reached out a second time when our tile shower was leaking and needed to be replaced. Again he did an amazing job completely redoing our shower and it turned out beautiful. He makes these stressful times easier as he is very understanding and easy to talk too. I highly recommend Dean and you will be very happy with the results."

"Did a great job. Built mailbox stand with an excellent custom flair. Built for strength. Texted and came right away. The message transition to know who was talking to me was confusing at first. DP was also not sure who it was initially."

Barndominium Builders FAQs, answered by experts

In the U.S., original and converted carriage houses are most often found in New England, New York, and other parts of the Northeast. New construction carriage houses can be found across the country, and are often added to properties with Colonial-style homes for additional living, storage, or work space, although they can be found in many different styles.

The construction stage is almost always the longest part of building a house. Within this stage, framing often takes the most time, lasting anywhere from one week to a couple of months, depending on the home's size, the crew, and the time of year. Other parts of the construction phase include pouring the foundation and installing doors, windows, a roof, siding, drywall, and flooring. The planning and design phase can also be very time-consuming, sometimes taking months or even years, especially for a custom home. The final finishing process, which includes painting and installing trim, is typically shorter than the construction or planning stages.

Building a tiny house is the least complicated way to build, especially if you’re tackling the project as a DIY. The smaller size means less complex plans, more straightforward utility installation, and fewer ways to make costly errors. Tiny homes still need to conform to building codes and often have other applicable regulations, so be sure to get the proper permits and confirm your build is by the book.

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.

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.
