"We were looking to remodel our kitchen or bath for a few years. We kept getting estimates from different companies and always felt the price was off or the person was not a good fit. Then, finally, we met Shai with Cal Green Remodeling. What a great guy! He is very upfront and honest about what we can expect in terms of cost and work flow. Because of his honest approach, we hired him. We felt he gave us the good and bad and how to resolve the bad as well. In the end, the process was fairly smooth, and the few hick-ups we had, for example, the city and their permit process, were well explained to us at the beginning, so we were ready. Our kitchen or bath looks amazing, and I plan to work with Cal Green Remodeling again. Thanks Shai!"

"I found Build the Bay through Angi’s List and I’m so glad we went with them for our bathroom update/remodel! Working with Eitan and his team was like night and day compared to other contractors I have worked with in the past. Specifically what I appreciated is that he treated me with respect and would take the time to explain in layman’s terms what was needed. (I’m not a construction pro by any means.) Eitan even shared a list of vendors that he has worked with in the past for materials and finishes, as well as a checklist to ensure I ordered all the finishing pieces in time. He would even be willing to review any products I was interested in to let me know if it was good quality. It’s only normal for unexpected issues to come up during construction, and what was also great is how communicative Eitan and his team were with me. They would quickly let me know what the issue was, explain what my options were, the cost for each, and what those options would mean in the long run. Eitan always responded very promptly via email or text if I had any questions or requested any updates. Our project has been done for about a month now and I have to say that I strongly feel like Eitan and his team delivered high quality bathrooms in a timely manner. I would definitely reach out to the Build the Bay team again if we needed to do work on our home again."

Custom home building FAQs
Typically, it’s more affordable to buy an existing home than it is to build a new one. New construction loan interest rates tend to be higher than interest rates for traditional mortgages. Additionally, the cost of materials is likely higher when building a new home than it was when an existing home was built (unless it’s a very new one). You’re also paying for all new appliances, finishes, permits, inspections, and connections for water, gas, and electricity.
One starting point to find a local home builder is to collect suggestions from friends and neighbors. However, it’s still wise to do some more research before you hire a builder. Read reviews to supplement any word-of-mouth recommendations. Check sources like Angi that have standards and criteria in place to screen the pros it lists can also help you find more reputable local home builders.
The average price per square foot to build a house is about $150 per square foot. Overall, the cost to build a house ranges anywhere from $100 to $500 per square foot, depending on where you build. The primary cost factors include location, size, and style of house you build.
The average cost to hire an architect for your home project ranges between $2,200 and $10,500. However, depending on location and project type, you might end up paying as little as $600 or as much as $45,000 or more. For example, the average cost of hiring an architect in North Carolina is between $1,800 and $2,000, but in California, that price tag jumps to $3,600 to $15,200.
The price you pay for your architect also depends on their experience level. For example, a principal architect, the firm's owner, typically charges $150 to $250 per hour. However, an intern architect with three to five years of experience usually only charges $45 per hour.
Knowing if you need an architect for your project can be tricky, especially if you've never worked with one before. In general, small remodeling projects like replacing fixtures typically don't require the expertise of an architect. However, larger projects, like moving walls or adding an addition to your home, should include an architect to ensure the project is structurally sound.
