"The best! Keith, Hank, Michael and Grant were a pleasure to work with over the course of several months last year. I have dealt with many contractors, both personally and professionally, and I can tell you that they should be your first call on any project. The work was done on time and on budget. We added some things to the project, but in no way did they push us to add a single additional item. In fact, we added a complete rebuild of the deck after the project had begun and there was no premium on the additional cost as compared to other contractors who know they have a captive audience. They were present at the property nearly every single day of the project, including Saturdays, as opposed to other contractors who simply give the work to subcontractors and check in once or twice a week, at best. In other words, they know what is going on at all times and are able to give guidance and direction to the subs, and us, on site. They are also more than willing to listen and make any adjustments without crushing you with additional costs! And, they actually work and work hard (especially through the brutal, brutal summer heat last year when we lost our air conditioning for a couple of weeks). I have known Keith and the crew for many years and there is nobody else I would trust to complete such an extensive project which included: completely new roof, all new siding, replacement of every single window in the house (which Keith, Hank, Michael and Grant) did personally, new addition (which included replacement of primary first floor structural beam), new primary bath and primary closets, new flooring, whole house painting including ceilings and more. Lastly, they don’t bite off more than they can chew which sets them so far apart from every contractor we have ever dealt with. Personal touch, presence, attentiveness and excellent workmanship. Highly recommend!"

FAQs for custom home building projects in Mahwah, NJ
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.
