"Our garage conversion went off without a hitch, and I credit that entirely to Foster and his team. From day one, he listened to our needs and came up with a design that maximized every square foot. The finished space has a small kitchenette, a bathroom, and a fold-out bed for guests, making it perfect for both short-term visitors and long stays. The build quality is excellent, solid, well insulated, and thoughtfully finished. Foster crew was polite, professional, and kept the work on schedule, something we have never experienced before in a renovation."

"Dean and his crew did a great job, showing up on time and staying on schedule. The work included replacing a window with an exterior door, drywall, trim, new wall with interior door, relocating sockets, etc on my 1950’s two-story home in Northeast Seattle. I will hire them to do additional work."

The two guys who came to my house called first to make sure I was home, since they were done with their last job early and could arrive before I expected them.  They were courteous, professional, respectful and honest.  They cleaned up after themselves, took on all the assorted tasks that I had lined up for them, and put up with my curious kitties who wanted to know what was going on.

Pole Barn Builders FAQs, answered by experts

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 difference between a pole barn and a stick-built barn is in the construction. Large poles in the ground provide support for pole barns. For stick-built barns, 2-by-4 or 2-by-6 lumber (known as sticks) create a frame around load-bearing beams. Stick-built construction is far more popular for residential homes. Pole barns are more cost-effective because they require fewer materials and less labor.

Your foundation contractor will first need to remove the topsoil and any vegetation within 4 feet of the area around the barn. They’ll need to ensure they have clear access to the site to begin excavation, after which they can begin construction.

Average barndominiums last between 50 and 150 years depending on the materials they are made from, how well they are maintained, and the environment they are built in. Barndominiums are very durable and have a much longer lifespan than traditional wood homes. With proper care and maintenance, well-built barndominium homes can last generations. 

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.
