"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.

"Working with Nathan & KN Remodeling was the best decision we made when undertaking our garage conversion job. Nathan understood exactly what we wanted, knew our budget parameters and provided us with a range of options that helped us stay within what we were seeking to spend. We wanted it to be NICE, but didn't need to over-do any of the finishes and spend needlessly on areas that were going to be used in-frequently. The end result was fantastic. The workmanship was of the highest order, the job was executed efficiently and with constant communication and oversight. The whole job was stress free and delivered on time. I can't recommend KN Remodeling highly enough!"

"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"

"Needed a new lock for the kitchen door. Jaime set a time for an estimate. He arrived within the time frame, gave an estimate to include purchasing the new lock. Purchased the lock and installed it. When he finished, he cleaned up very well. Would definitely use him again when I need a handyman."

"Working with aright builders was an unbelievably satisfying experience …..Jorge and his brother Andy were consummate professionals and they accommodated every request and change order with positivity and good humor and never made me feel like I was asking too much. The finished product was better than I imagined it would be and they got it done in record time to accommodate my granddaughters high school graduation which was no easy feat with the COVID restrictions. I would highly recommend these guys for any home improvement project and if I need something done in the future these would be my guys."

"We bought a house from a smoker. We hired a separate company for the decontamination and Robert coordinated with them to be able to start the restoration after they were done. He had to paint EVERYTHING: ceilings, walls, closets, trim, doors.... We replaced ~80% of the flooring with tile and he was able to put in a beautiful medallion! He replaced a toilet, fixed other plumbing issues, installed ceiling fans on the patio, cleaned up the yard, changed all the doorknobs, repaired the garage door, replaced the keypad remote.... There were so many things, it is difficult to list them all. The property looks BEAUTIFUL and we plan additional projects for him. We highly recommend Robert to care for your home as if it were his own!"

"Our kitchen remodel with McCormick Home Builders went beyond our expectations. Leoni and her team took the time to understand exactly what we wanted. The open layout design changed the way we use the space, and it’s been perfect for family gatherings. They were prompt, courteous, and genuinely invested in making sure we were happy. Really impressed!"

"Ben did some remodeling for our house in 2017. He was clear about the necessary steps and was dependable. He showed up when he said he would, and the work was finished on time and on budget which is very rare for contractors. He also provided thoughtful solutions to an outdoor drainage issue we had in our older home. A couple of years later we also hired him to do flooring at my relative's house, and he again completed the work on time and on budget with his team. We have always loved working with him and would gladly use him as our contractor on future jobs."

Barndominium Builders questions, answered by experts

Tiny houses, often called tiny homes, need between 100 to 400 square feet, with the most common size being between 200 and 300 square feet. Tiny houses more than 400 square feet venture into apartment-size dwellings and may be considered more of a traditional house than a tiny home. The number of occupants, desired lifestyle, and furniture will all be major factors that determine the desired tiny house size.

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 may need a local building permit and written permission from your homeowner’s association to install a shed, especially if you’re doing any substantial land clearing or installing electricity or plumbing. Permit requirements vary between municipalities, so research the local laws before starting your project. If you hire a contractor to build the shed, they can help determine which permits will be necessary.

While building a treehouse isn’t necessarily a death sentence, damaging the trunk is one of the ways to kill a tree. If you’re concerned about the tree, opt for a treehouse support system rather than attaching it directly to the trunk. This may involve using bolts and brackets to affix the structure to the tree's branches or establishing a standalone support system that remains unattached to the tree.

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.
