"We hired McCormick Home Builders to remodel our living room, and we are beyond pleased with the result. The team was professional, worked efficiently, and Aris design ideas made a huge difference. The room feels so much brighter and more spacious. This was the best decision we made for our home, and we were already planning our next remodel with them."

"We had an addition built into our home to accommodate our growing family. We were a little nervous about having contractors in our home as I was pregnant at the time but the guys from RS Construction could not have been more professional. They always made sure things were kept clean and safe around the house as they worked. They did a beautiful job with the addition and the price was very fair. I highly recommend their services."

"OZ-ARI did an excellent job with my recent complete renovation. Quick to respond and great communication. They came highly recommended and provided amazing customer service. I want to give a special shout-out to the construction team because of the attention to detail and care they took with their work. Would definitely work with OZ-ARI again for any future home updates. I couldn't be happier with the results!"

"My wife and I purchased a home built in the ‘70s that was in good condition but in desperate need of a complete remodel. We had a clean, modern style in mind for our growing family and needed an architect to help us turn it into an actual design. That’s where YNG Architects came into play. We selected Yenny Ng and his team for design after interviewing several other firms because during the walk-through (a) he quickly played off and expanded upon our ideas, (b) provided pragmatic insight into the implications to build and construction, and most importantly, (c) had a gentle but confident manner that matched well with our working style. We were not disappointed. Over a period of several months we went through a systematic design process. Yenny and his team listened to our design preferences and took cues from example photos of design elements we admired. He lent his expert opinion and personal perspectives to balance pragmatic build versus splurging where we wanted to splurge (bi-fold doors between the indoor and outdoor space, yay!). He and his team worked well offline where we often exchanged and updated designs by exchanging emails and annotated PDF files—this was very productive as my wife and I both have demanding careers. He and his team also helped us through the city’s permitting process to get the requirements and details done; they were thoughtful and swift in responding to the city’s requests. There were no surprises with the design fees.  In the end, we have a beautiful modern and functional design that fits in well with the neighborhood. Over 65% of the existing home will be remodeled and an additional 30% new living space will be added. My wife and I were very pleased with the outcome and even more excited to see this design come to life for our family. We even have a Phase II project lined up with Yenny and his team to build out the outdoor living space. We would gladly recommend YNG Architects to our friends and family. Now, this also means the construction project will be large and complex and require an experienced general contractor. We did interview other builders but chose Yenny (via YNG Construction) for similar reasons as the design—experience, pragmatism, and working style. We look forward to this next phase of our home remodel."

Custom Home Builders FAQs, answered by experts

Buying a house is easier than building one from scratch. Buying an existing home is almost always faster, even if you need to make renovations once you move in. When you hire the right team to build a home, they will simplify the design and build phases so that there is little guesswork throughout the process, but building new construction will almost always take longer than buying an existing home.

Ultimately, a work warranty is only as reliable as the contractor you’ve hired. That’s why trust and reputation are such important factors, in addition to having a solid contract and confirming appropriate licensing, insurance, and bonding. When looking for a contractor, it’s a good idea to read online reviews and ratings to see what kind of experience past customers have had. Issues with your contractor can make for an unsatisfying renovation process, but a reliable contractor can make the process go as smoothly as possible.

The most significant expense when building a barndominium is constructing the metal shell, which includes the roof, doors, and windows. Additional exterior components impacting the overall cost include metal siding and the concrete foundation.

Custom homes can take an average of 18 months to build, mainly due to the lengthy design process, and most projects take somewhere between 12 and 24 months. When you work with the right custom home builders near you, they can help you map the road ahead and understand what can speed up or delay the timeline. Choosing locally available materials, for example, can speed things up without losing that customized touch.

Start by researching local contractors with experience in cottage construction. Ask for references, check licensing and insurance, and review completed projects. Compare multiple bids, making sure each includes the same scope of work. A good contractor will communicate clearly, provide a detailed contract, and ensure all work meets code and safety standards.
