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."

"I needed my deck stairs repaired. This involved raising the top of the stairs up into place and engineering a beam system to support the. Ethan responded promptly and offered a solution at a reasonable price. Ethan is a hard worker, very efficient, and doesn't stop until the job is done, plus he is a nice guy. He is now on my go-to list for home maintenance."

Barndominium Builders FAQs, answered by experts

Adding an extension or addition to your home costs more than a loft conversion in all but the rarest cases where the home's structural integrity is lacking. Because a home addition requires a new foundation section or significant structural upgrades to handle a cantilevered portion, the cost compared to almost any loft conversion is significantly greater for the same square footage.

The most common slope, or roof pitch, for a shed is 4:12 or four inches of height for every horizontal foot. For areas that experience heavy snow loads, a steeper roof of 6:12 or 9:12 is best. 

Choose a barn door with an extra two to three inches on either side of the frame. The width of the barn door will depend on the type and placement of your track, but in most cases, an additional inch or two will do the trick.

You don’t typically need a permit to build a shed, but it’s best to check with your local city clerk to make sure before you start the project. Every town, city, and municipality can have different rules when it comes to any home improvement project. Homeowners associations sometimes have restrictions on the materials you can use on your property as well.

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.
