"(1) Excellent work, neat, clean, efficient, timely done, and we’re very happy with the results. Tim’s friendly personality makes it easy to communicate ideas with and we appreciated his suggestions. We will definitely use Tandem Trades again in the future. (2) Great ideas for interior design, colors and layout. In a matter of days we were presented with a living room floor plan, and ideas and fabric samples for furniture and accessories. We implemented the suggestions which contributed to the quick sale of our home - much sooner than most homes in the area. We will be consulting with them again on our new home,"

"We hired Dana King to build our garage and we were so pleased by the result we hired them to remodel our kitchen. Dana and her team do an excellent job communicating throughout the construction project, keeping to their budget, and their designs are simply beautiful. We couldn't be happier with their work to make our home a place of tranquility."

Hello there! I'm a Saint Charles/Saint Louis native and an experienced carpenter and remodeller of 17 years! Been in my own business since 2022. I love to do beautiful work at reasonable prices. I am focused on design-minded small construction and carpentry--this means that I am not primarily so focused on flashy features and the newest updates, and more focused on how I can create a project with you that makes sense with your specific house and it's architectural design. I love working with wood the most but really love doing most anything on a home and happy to do handyman work here and there as well. Please reach out so we can start a conversation! I'm happy to offer advice on how to navigate the construction industry or send you phone numbers of other great guys if you need other services. I focus on approachability and a down to earth experience. I love doing good work, i'm easy to deal with and show up when I say I will. Would love to work with you!

Customers say: Quick response

"Everyone on this team is fantastic. We originally met with Jacob, who was incredibly detailed in the notes he took. He spent a good amount of time with us at our initial meeting to truly understand what we wanted to accomplish. For the second meeting, we met with Jacob and Brian to go over some more items in detail. This is our first home and we relied on their experience when we weren't sure which direction to head into with some areas. The entire team was patient and respectful throughout the entire process, provided updates throughout our remodel, and gave recommendations when we needed them. Everything turned out how we wanted it to and we couldn't be happier. We'll definitely be using them in the future for other projects."

"I have used Project Arcadia for multiple projects at a few different properties. From emergency plumbing to a full deck build. There is no job these guys can't handle. They are very detailed oriented and professional. Most importantly you can trust them to do what they are contracted for on time and within budget. They really go the extra mile and do quality work."

Barndominium Builders questions, answered by experts

Yes, barndominiums are energy-efficient as long as insulation professionals properly install quality insulation, windows, and doors. Utility bills for barndo living can be up to 50% lower than those for a traditional home.  Make your barndo more energy efficient by working with contractors and HVAC professionals to strategically place windows, doors, and heating/cooling systems. 

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.

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.

The maximum size of a tiny home you can move depends on your state transportation guidelines, but the rule of thumb is a maximum of 400 square feet. However, as long as it falls within the local limits for traveling on public roadways, you should be good to hit the road.

The foundation for a pole barn should be at least 36 inches thick to ensure that the piers won’t shift from frost heave.
