"We hired MHI Home Improvements to renovate our entire Kitchen in Bethpage, NY. We are so happy with the work ethics and final product. His staff would sweep every day before they ended for the day and make sure they left everything clean and tart early on time the next day. The entire job was finished timely and we get compliments all the time. My wife and I are more than happy to recommend MHI Home Improvements for any of your home improvments!"

"Gary and the team did a great job. My wife wanted a timber frame look to the front entrance and the guys created an amazing custom look. Gary made some design suggestions along the way, and we think they really enhanced the overall look. This is the 4th or 5th time we have used Kentstruction and I cannot say enough great things about them."

"Malik at Al-Arsh Construction runs a very professional standard. His contracts are accurate, his prices are fair, and his ability to make the scope of the job efficient and cost saving were well communicated. I have utilized him twice for two major projects on my 150 year old home. You open up a wall and discover ten more repairs. But Malik was accurate in his estimates, and any change of orders were for additional work that I requested as I saw the project develop. His suggestions were based on common sense, and I was always comfortable going forward with any change of orders. Malik scheduled the work and came every day, on time and with the same skilled workers. He was on site often, and managed the work and workers' time very efficiently. The projects were done to perfection and detail and to contract. I like contracts. Malik was also very reasonable and was negotiable to labor costs when I wished to purchase materials myself. Like when I wanted to use a certain wallboard and frame. He is very much a Contractors', Contractor. I come from a family of old Italian contractors and they would be proud that I hired Malik to do the work.

"From the first meeting we had with the owner, John we felt completely comfortable in knowing he was honest and knowledgeable in his trade. His team was always there when they were expected and always courteous and respectful of our home. Although we had some bumps along the way which had nothing to do with the company they always took it all in stride and were readily available in person or by phone with suggestions and solutions. They completed the job above our expectations and in the time frame we were promised. We highly recommend 112 Home Improvement and will be using them again for future renovations!"

Custom Home Builders FAQs, answered by experts

The average build timeline for a home is between six and 12 months, with timelines pushing toward the upper end of that range if you’re creating a custom design or need a lot of land preparation before getting started. Hiring a general contractor or a custom homebuilder will help speed up the process, as you’ll see fewer delays between different parts of the build process getting done.

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.

Modular homes can be a great investment, especially for those who find the prices of stick-built real estate too high. Modular homes are usually much more affordable because they’re mass-manufactured and then assembled on-site or delivered mostly assembled. If they’re installed properly and by professionals, they can last for between 50 and 100 years, potentially making them an outstanding investment.

A-frame homes are on the smaller side. While there’s no set square footage amount it has to be, it will usually come in around 1,000 square feet or smaller.

Ranch and colonial-style homes are often the most affordable to build. They have a common layout with available designs that are easy to adjust in simple ways without having to spend too much on a structural engineer or architect. Both types of homes' symmetry, simple roofs, and often one or two-story plans mean they often fall in the $150 to $200 square-foot range, putting them right around average.
