"RUN FAR AWAY FROM ALLIED AND TOM. Tom took my money and did not complete the renovations as per our contract. He lied about having a licensed electrician to do electrical work, it was just one of his workers who's not licensed. I paid for a dumpster and when it was delivered by tom it was already half full from another allied job and I was asked to pay the full amount of $950. Tom didn't listen to anything I said regarding the work I requested and he changed my design and did work that was cheaper for him. I was priced for one of my ceiling's to be ripped out and reinstalled with new sheetrock, Tom waited until I was away on business then he installed sheetrock on top of the bad sheetrock and told me he ripped out the old sheetrock and installed the new sheetrock, I found out when my EC cut holes to install lights and we found 2 layers of sheetrock preventing the lights from being able to be installed. Allied construction is a cheap, sneaky company who will steal your money and breach your contract. Do not hire these people Tom is a lair. Tom wore a gun in my house on his hip and told me "I use this to get paid by customer who don't want to pay". Tom left live 120v wires hanging out of the walls and ceiling, he removed a banister and didn't replace it for 3 weeks making my home very unsafe for me and my 9 year old son."

FAQs for custom home building projects in Holtsville, NY
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.
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.
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.
