Customers say: Quality work

"We used F and F Construction to help repair and replace boards, spindles, and steps at our Urbandale home on 158th street. Brent and Matt were fantastic in getting the job done quickly and did quality work. We talked for awhile after the job was finished. They are easy to talk with and know what they are doing. I highly recommend them to other home owners in the area. -Winston Morris."

"Starting from scratch to find a reputable contractor to demo and build a custom garage for me in Beaverdale Iowa. Hoss stood out from the dozens of contractors who I connected with as the frontrunner through timely communication, knowledgeable expertise, turn-key options, customer referrals and a tru interest in understanding my needs and working with me to find the best affordable options. His work was on time and delivered as expected. It’s also important to note that Hoss and his crews worked with me virtually to deliver this project remotely as I was away most of the time. Finding reputable trade professionals is increasingly difficult and we consider ourselves fortunate to have found Hoss and his crews. Thank you."

Barndominium Builders FAQs, answered by experts

The best lumber for building will be the strongest and most eco-friendly wood your budget allows. That being said, Douglas fir, pine, oak, and maple are all common building materials. Contractors will use a strong, inexpensive wood to frame a house or other structure and finer woods like mahogany for detail work. 

Ranch and colonial-style homes are often the most affordable to build. They have a common layout with available designs that are easy to adjust in simple ways without having to spend too much on a structural engineer or architect. Both types of homes' symmetry, simple roofs, and often one or two-story plans mean they often fall in the $150 to $200 square-foot range, putting them right around average.

The timeline to build your barn will depend on the barn type and the company you hire. A pole barn may take six weeks or so, while a traditionally framed or steel-framed barn can take four months or longer. Building a barndominium takes the longest because you are essentially building a new home. You can expect barndominiums to take six months or longer to build.

Building a treehouse can vary in difficulty depending on factors such as design complexity, size, and the builder’s woodworking experience. Basic treehouses with simple designs can be manageable for DIYers with some carpentry skills, while more elaborate structures may pose challenges. Adequate planning, research, and careful execution can make the process more manageable, and resources like premade plans or professional assistance are always available for additional support.

While sheds are most certainly helpful for most homeowners, unfortunately, sheds do not add value to a home or property in the traditional sense. However, if the home has limited storage or garage space, having a shed to store things like decorations or lawn equipment can certainly be a positive if you want to sell.
