"We needed the window trim, made of wood, on our 2nd story home replaced, patched, caulked & painted. The two arched windows needed the wood replaced & the others repaired. The windows look better than the original one done. The guys did an excellent job, very professional & cleaned up afterwards too. Will definitely use again for other projects around our home."

"So Cal Builders & Design Inc made the entire building process stress-free. They were transparent with costs, delivered work on time, and ensured every design detail was perfect. I couldn’t be happier with the final results."
Completely renovating both the guest and master bathrooms. In the master bathroom, we're installing a spacious walk-in shower featuring dual black-finished shower heads, elegant floating benches, and marble wall tiles. Meanwhile, the guest bathroom will have a sleek built-in tub and stylish hexagon tiles.
This project involved adding a new master bathroom to the existing house. The shower features sleek white subway tiles complemented by striking black fixtures and shower door hardware. The bathroom floor is adorned with elegant white marble tiles, providing a seamless and luxurious finish. A white shaker vanity topped with a white marble countertop completes the space, creating a clean and sophisticated look.

"The KN Remodeling team did an excellent job at our home completely remodeling 3 bathrooms, painting our entire home and rebuilding a huge planter outside. We trusted them in our home while we are out of town almost the entire time. We hired them back to do additional work in our home that they did quickly and expertly. The team was professional, very friendly, worked quickly, quietly, cleanly, and I would highly recommend them."

"Even with all the delays due to Covid Jose finished this project as the materials came in. We had a several month delay due to Covid on getting our fireplace doors and Jose came right after they finally were installed and completed the project in just a few days. We found his name on Home Advisor and I would highly recommend this company. We found his na"

"Jorge, Andy and their team at A1-Builders were knowledgeable, honest, reliable and above all always available to answer any questions we had. They helped build a 2 bed 1 bath 600sqft addition to our home during the lean months over the pandemic. We had multiple projects (pool, patio, retaining wall) going on at the same time with other contractors and the crew from A1-Builders were by far the most professional. They always made sure that they left their work site clean after each dayâ s work. Jorge will definitely be the first person I call for our next home project because I know that even if he does not have the time to do the work, he will always guide me in the right direction. Thank you again to the entire A1-Builder team!"

"Robert and his crew did an outstanding job in a short time frame of one week in which I needed the work done for a house inspection to sell the home.  He taped off everything to reduce the dust created from sanding the drywall.  He left the house cleaner than it was when he started.  He was on time to bid the job and stayed on time to complete the job.  I really recommend him for work that touches several labors.  I had other estimates, but they needed to sub out part of the work because they couldn't do drywall, painting, and electrical.  Robert is the complete handyman that can do just about anything and his prices are very fair. When I have other work, Robert would be my first choice.

"After dealing with frequent roof repairs, we finally decided on a complete replacement for our Livermore home. Avi kept us informed every step of the way, and the finished roof exceeded our expectations. It's made a noticeable difference during hot summer days."

Barndominium Builders FAQs, answered by experts

This answer varies based on where you are, but most states require that all homes are greater than 320 square feet. Remember that four walls are not the only requirements—windows, closet space, minimal ceiling heights, and indoor air quality are also factors. Each state and municipality differs, though, and as some don’t consider tiny homes permanent shelters, you’ll need to check to ensure you aren’t violating any local or state laws with your build.

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.

It can, especially with the rising popularity of treehouses that go beyond the ones designed for kids. Adults can now use them as office spaces, yoga studios, or quiet treetop retreats. That said, a treehouse can appeal to families with children or adults who might want to convert it into a space of their own. Depending on the buyer, they may be willing to pay extra for the unique feature.

Rustic and modern farmhouse styles are currently the most popular. These include rustic and antique furniture, muted colors, clean lines, eclectic decor, and natural materials. Some other popular farmhouse styles include the following:

  • Coastal farmhouse: Creates a lighter, airier feel with soft colors and blue palettes, along with gold

  • Colonial farmhouse: Focuses on real antique furniture and decor

  • French farmhouse: Leans on French country architecture and design by including marble and lighter-colored metals, like zinc

  • Industrial farmhouse: Includes thick, chunky furniture and dark metals

  • Scandinavian farmhouse: Usually includes lighter wood colors and more refined furniture

The steep slope of an A-frame roof withstands high winds, heavy rain, and heavy snowfall, making them popular all over the world. A-frames also offer simple, quick construction. Finally, an A-frame typically has large windows on the non-roof sides to let in a maximum amount of natural light. Consequently, they are often an affordable building solution for the right homeowner and location.
