"Satisfied customers reporting! We're writing this review four months after the completion of our bathroom renovation. We've been thrilled with the final product and the experience of signing with Ouri from day one was a pleasure. This was our first large project and we would undoubtedly hire Ouri again. Project We instinctively knew Ouri was the best fit for us after the on-site consultation. Not only are his reviews overwhelmingly positive, but he's knowledgeable, respectful, patient, and honest, with competitive pricing to boot. He's also a very responsive communicator. We needed some time after signing the contract to shop for materials. Ouri kindly rolled with our uncertain timeline, checking in periodically without any pressure to see where we were at and advising on any questions we had along the way. From the beginning of the project, his crew was respectful, clean, and always checked in with us as any questions came up. The project went smoothly and for one very minor hiccup that came up, Ouri & crew were quick to address without question. And months later, he sent a member of his crew to come troubleshoot something minor, again without any hesitation. It's challenging to keep these brief when you have such a great experience, especially when you read and hear about horror stories from other people. Selfishly, maybe we should keep this to ourselves so he isn't so busy when we need him for another project in the future :) Scope The bathroom was totally gutted save for some sections of drywall. A full tiled shower with a bench was installed (replacing a tiny old corner unit!), along with added lighting & exhaust fan, new floor tile, and all new fixtures/ cabinets/ paint. The plumbing and the shower drain were relocated. An old window was removed and replaced by a new one on an adjacent wall."

Whether you're upgrading an existing structure or building from the ground up, Peter T. Erdelyi & Associates, Inc has the expertise to oversee your project through completion.

Our team of professional engineers, drafters, expeditors and project staff will deliver plans that withstand the test of time.
"The work Erdelyi associates did is great, but communication and timeliness were lacking. I didn’t have a consistent point of contact throughout the project - it just seems my project was handed off from one person to the next with no continuity and I had to proactively reach out for updates."

"Stuff happens, and this business knows how to handle it! We had a stain on the ceiling. Ofri from BTB came over and turned on the water from the upstairs bathtub and then the shower stall. The ceiling became moist after the shower was turned on. Ofri then came back with a plumber. He turned on the upstairs bathtub. After they left, water dripped from the ceiling. Ofri had the plumber immediately send over a team for a service call. They broke open a hole in the ceiling and found that a pipe leading to the bathtub was so rusty it had holes. They took videos showing other pipes leading to the bathtub were also very rusty. While the team was still there, Ofri gave us prices, sent over the paperwork and the pipes were replaced within a of couple hours. Fabulous! Ofri had thought it would take a lot longer to complete the plumbing work. Therefore, her pricing did not align with the actual work performed. She brought in Alon, who substantially reduced the price to our satisfaction. Their responsiveness and reasonableness earned them my highest rating. Thank you Ofri, Alon and the BTB team!"

"I recently had Buildwright Construction remodel my entire home, and I'm thrilled with the new look. They have a laid-back California style that's both cool & caring. There was a small mix-up with the paint in one room, but as soon as I noticed, the project manager took care of it. They came back quickly to repaint the room, making sure it fit perfectly with my home’s vibe. Even with that little hiccup, my home feels fresh, warm, and inviting. I appreciate how Buildwright Construction handled the mistake with care and professionalism. If you're looking for quality work with a genuine, down-to-earth touch, I highly recommend them."

"The remodeling of my guest bath went very smoothly. I had few ideas as to what I wanted, but thanks to Nathan's design help, I was able to select the items that fit my concept. Many reviews talk mainly about the job and the results, but there is one important area that is often neglected: the working crew.

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.
