"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

Yes, you can use a storage shed several ways, including as a chicken coop, but you'll need to make some modifications. You will have to add a chicken door, roosts, ventilation near the roof, mesh on the windows, and insulation if you live in a colder climate. Additionally, you’ll want to ensure that the shed is predator-proof so no other animals can harm your chickens. You should also add a run and nest boxes to your shed.

Rather than using a common two-by-four piece of wood for a rafter, you probably will use two-by-six, two-by-eight, two-by-ten, or even two-by-twelve boards. Wider lumber is typically a better choice in a larger building as it provides more sturdiness. Some installers may use wider lumber for rafters near the edges of the roof, where the greatest stress occurs, and save money with narrower lumber toward the middle.

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. 

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. 

You can use a variety of wood to build a barn door, but the most common options include 1-by boards and 2-by boards for the backing and the decorative boards on the front of the door. Softwoods like pine will save you some money and should hold up well, while hardwoods like maple and oak will stand up to more wear and tear. You could also build the backer out of plywood to minimize the cuts you need to make. Whatever you decide on, make sure the width of the wood is compatible with the mounting brackets you buy.
