What Factors Impact a Home Addition Estimate?


Perhaps you’ve been thinking of adding an addition to your home, which is less time-consuming and expensive than moving to an entirely new property. You’ll likely reach out to a number of home construction companies in your geographic area for estimates. Knowing what’s factored into the estimate for home additions can help you narrow down your options and make a well-informed decision.

Project Scope

One of the biggest factors when it comes to pricing estimates is how large of an addition you desire. Besides the overall size of the project, try to narrow down the specific materials and construction type you want. That way, you can receive a more exact estimate.

Have you ever ordered something online only to receive it in the mail and have it look nothing like the images you saw on the website? You may feel your purchase wasn’t worth the money you paid for it. The same applies to home additions. See if the construction companies you’re considering would be willing to come out to your home to take a look at the site. That way, more precise measurements and images can be taken.


Any work on your addition that requires outsourcing is likely to drive up the cost. This is another reason to have a contractor come out to your home. Contractors who use subcontractors may have to factor in additional estimates when compiling your estimate.


Do you know what specific materials you’d like used in your addition? This is something else that has a sizeable impact on your estimate. Not only do you have to factor in the overall cost of the material, but it can also be more expensive to order materials from a supplier who isn’t local.

Once you have a few estimates for home additions, do a careful comparison. Know that the lowest estimate isn’t necessarily the best, nor is the highest. Rather than focus on price, you’re better off turning your attention to the best final results and how your addition will withstand the test of time.
